Real-time pollen data for Alpharetta — updated daily.
Microscopic arachnids that feed on shed human skin and colonize mattresses, pillows, upholstered furniture, and carpet. They require relative humidity above roughly fifty percent and are most productive between 68 and 77 degrees — conditions modern climate-controlled homes maintain continuously. Alpharetta's airtight newer construction exchanges little air with the outdoors, trapping indoor humidity and allergen. Unlike pollen, dust mite exposure has no seasonal break, and bedrooms represent the highest-concentration environment because of prolonged nightly contact.
Oak is the dominant outdoor tree allergen. White oak, red oak, water oak, willow oak, and post oak occur across Alpharetta's extensive canopy, which shades more than half the city. Oak grains are microscopic and remain airborne for hours, penetrating deep into the airways.
Both are abundant across Alpharetta's mature hardwood cover and both are significantly allergenic. Sweetgum is especially prevalent along the Big Creek bottomlands. Together with oak they compress into an intense late-March-to-April window rather than staggering.
Loblolly and shortleaf pine occur throughout residential neighborhoods and corridor forest, producing the visible spring yellow film. Grains are large and less efficient at reaching deep airways than oak, but volume makes pine a meaningful irritant for sensitive individuals.
The Big Creek corridor supports river birch, sycamore, box elder, green ash, and red maple beneath dense canopy. Cedar, juniper, elm, and maple open the season in February. Boardwalk sections cross wetland and marsh where humidity remains elevated.
Wills Park's sixty-acre equestrian facility introduces allergens uncommon in suburban settings. Horse dander is a well-established trigger. Hay, straw, and stored feed harbor storage mites — relatives of house dust mites that live in grain and forage and cross-react with them immunologically. Stable environments also carry elevated mold from damp bedding and hay.
Bermuda grass dominates lawns, parks, athletic fields, and corporate campus landscaping. Fescue and ryegrass are common on shaded residential lots. Johnson grass grows along greenway margins and roadway corridors.
Ragweed is the dominant fall allergen, with greenway edges, utility easements, and roadway margins providing habitat. Pigweed, lamb's quarters, nettle, and plantain contribute. Goldenrod blooms conspicuously alongside but is insect-pollinated and produces little airborne pollen.
Big Creek wetlands and bottomland sustain outdoor fungal spore production, with Cladosporium and Alternaria peaking in late summer and early fall. Indoors, Aspergillus and Penicillium persist year-round, and tight building envelopes that trap humidity favor them. Piedmont red clay drains slowly, holding water against foundations after thunderstorms.
GA 400 runs through the city with five exits, and Old Milton Parkway, Windward Parkway, North Point Parkway, and Haynes Bridge Road carry heavy commuter volume. Diesel and fine particulate inflame airway linings and amplify reactions to biological allergens during peak periods.
Severity: Moderate. Outdoor pollen is dormant, but this is when indoor allergens dominate most completely. Closed windows, continuous heating, and airtight construction mean dust mite and pet dander exposure runs at its highest relative share of the year. Residents who assume winter means relief often find symptoms persist — a strong indication that indoor allergens rather than pollen are driving them. Cedar and juniper may begin by mid-January.
Severity: Moderate. Maple, elm, cedar, and juniper lead. River birch and box elder begin along the Big Creek corridor. Oak, hickory, and pine start ramping across Alpharetta's extensive canopy. Indoor dust mite levels remain elevated as heating continues. Counts climb steadily.
Severity: Severe. Oak, sweetgum, hickory, and pine peak together in a compressed window across canopy shading more than half the city. Bottomland species along the greenway compound the load. The visible pine film coats surfaces. Outdoor and indoor exposure overlap at their combined maximum. Dry, windy afternoons spike counts sharply.
Severity: High. Tree pollen declines as Bermuda grass surges on lawns, parks, and corporate campuses. Summer heat and humidity build, and air conditioning season begins in earnest — tight homes now trap warm humid air, pushing dust mite populations toward their annual peak. Big Creek wetlands hold moisture, raising outdoor mold. Thunderstorms begin.
Severity: High. Ragweed begins in August and climbs through September along greenway edges and easements. Indoor dust mite populations reach their annual maximum in the warm humid months. Alternaria and Cladosporium peak outdoors in the Big Creek bottomlands. This is the period when indoor and outdoor allergen loads are simultaneously highest.
Severity: Moderate to High. Ragweed persists into late October, extended by warm autumns. Goldenrod blooms alongside but is not the cause. Heavy leaf fall across the canopy and greenway generates Cladosporium and Aspergillus. As heating begins and windows close, indoor allergen exposure rises again toward its winter share.
Pollen gets the attention because it is seasonal and dramatic. Dust mites get almost none, because they are invisible and constant — and in Alpharetta they are the allergen most likely to be affecting you year-round. Dust mites are microscopic arachnids that feed on shed human skin and live in mattresses, pillows, upholstered furniture, and carpet. They require relative humidity above roughly fifty percent and thrive between about 68 and 77 degrees — which is to say, they thrive in precisely the conditions a well-run modern household maintains twelve months a year. Unlike oak or ragweed, dust mite exposure has no off-season. If your symptoms never fully resolve even in December, or if you wake up congested and improve after a few hours out of the house, dust mites deserve investigation before you attribute everything to trees.
This is counterintuitive and worth knowing. Modern construction is built to be airtight — sealed envelopes, high-performance windows, continuous insulation — because air leakage wastes energy. The trade-off is that tight homes exchange far less air with the outdoors, so whatever is generated inside stays inside: humidity from showers, cooking, and breathing, along with dust mite allergen and pet dander. Older leaky houses were expensive to heat and cool, but they effectively ventilated themselves. Alpharetta's large newer homes in planned neighborhoods, with generous carpet and soft furnishings, combine low air exchange with abundant dust mite habitat. The fix is not to make your house leaky — it is to control humidity deliberately and reduce the reservoirs.
Dust mite control is one of the few areas of allergy management where specific household measures have real effect. Keep indoor relative humidity below fifty percent — buy an inexpensive hygrometer and check it rather than guessing, and run a dehumidifier if your reading is high. Use allergen-proof zippered encasements on mattresses, box springs, and pillows, which physically separate you from the largest reservoir in the house. Wash bedding weekly in hot water. Vacuum with a HEPA-filtered machine, and consider reducing carpet and heavy drapery in bedrooms specifically, since that is where you spend eight uninterrupted hours breathing. Upgrading HVAC filters to MERV 11 or higher helps with circulating particulate.
Alpharetta anchors one of the Southeast's densest concentrations of technology and corporate employment along the GA 400 corridor. For a great many residents that means the day runs from a sealed house to a sealed car to a sealed office building and back. Office environments carry their own load — shared HVAC systems you cannot adjust, wall-to-wall carpet, and filtration decisions made by a building manager rather than by you. If your symptoms are worse on workdays than weekends, or improve markedly on vacation, the building may be contributing. You can control your home; for the office, a personal HEPA unit at your desk and a conversation with facilities about filter schedules are the realistic levers.
Wills Park includes a sixty-acre equestrian show facility, among the finest in the Southeast and genuinely unusual for a city this size. Horses bring allergens that most suburban residents never encounter: horse dander is a well-recognized trigger, and hay, straw, and feed carry storage mites — close relatives of dust mites that live in stored grain and forage and cross-react with them. Stable environments also carry high mold loads from damp bedding and hay. If you ride, work at the facility, or have children in equestrian programs, and your symptoms flare at the barn specifically, that pattern is worth testing for rather than assuming it is just the outdoor pollen.
The Big Creek Greenway runs roughly twelve miles within Alpharetta, with sections of elevated boardwalk crossing wetlands and marsh beneath dense mature hardwood canopy. That canopy delivers heavy oak, sweetgum, and hickory pollen in spring, and the wetland sections sustain fungal spore production through the warm months at levels above the surrounding uplands. It is a genuinely lovely corridor and it concentrates outdoor allergens. Late morning after fog and dew have burned off is generally better than dawn, and after rain is better than a dry breezy afternoon.
That pattern usually points to indoor allergens rather than pollen — most often dust mites. They feed on shed human skin, live in mattresses, pillows, upholstery, and carpet, and need only humidity above about fifty percent and temperatures between roughly 68 and 77 degrees. A climate-controlled home supplies both continuously, so dust mite exposure has no seasonal break. Waking congested and improving after a few hours out of the house is a classic sign.
Sometimes, yes. Modern homes are built airtight to conserve energy, which means they exchange much less air with the outdoors. Humidity generated inside — from showers, cooking, and breathing — accumulates rather than dissipating, and so does dust mite allergen and pet dander. Older leaky homes ventilated themselves inefficiently but constantly. The answer is not a leakier house, but deliberate humidity control and reducing the reservoirs where mites live.
Keep indoor relative humidity below fifty percent — use a hygrometer rather than guessing, and run a dehumidifier if needed. Put allergen-proof zippered encasements on mattresses, box springs, and pillows. Wash bedding weekly in hot water. Vacuum with a HEPA-filtered machine and consider reducing carpet and heavy drapery in bedrooms specifically, since that is where you spend eight uninterrupted hours. Upgrade HVAC filters to MERV 11 or higher.
Office buildings have their own allergen load: centrally managed HVAC you cannot adjust, extensive wall-to-wall carpet, and filtration schedules set by building operators rather than occupants. If symptoms track the workweek and ease on weekends or vacation, the building is worth considering. A personal HEPA unit at your desk and a conversation with facilities about filter maintenance are the practical options.
For people who spend time there, yes. Horse dander is a well-recognized allergen, and hay, straw, and stored feed carry storage mites — relatives of house dust mites that cross-react with them. Stables also carry elevated mold from damp bedding and hay. If your symptoms flare specifically at the barn, that is worth testing for rather than assuming it is outdoor pollen.
Late March through April is worst outdoors, when oak, sweetgum, hickory, and pine peak together across canopy covering more than half the city. Grass runs May into September. Ragweed peaks August through October. Dust mites, however, remain elevated all twelve months — which is why many Alpharetta residents never get a genuine break.
Yes. HeyAllergy provides telemedicine appointments with board-certified allergists licensed in Georgia. No waitlist — particularly useful for corridor professionals whose schedules do not accommodate midday clinic visits. Available throughout north Fulton including Alpharetta, Milton, Roswell, Johns Creek, and surrounding communities.
HeyPak® sublingual immunotherapy drops are customized based on allergy blood test results. For Alpharetta residents, this targets local oak, sweetgum, hickory, pine, Bermuda grass, ragweed, mold, and dust mite allergens — dust mites included, which matters given their year-round presence here. Daily drops placed under the tongue retrain your immune system rather than just suppressing symptoms, with improvement typically seen in 3–6 months. Treatment is recommended for 3–5 years for lasting relief. Starting at $47/month.

Alpharetta is a city of approximately 67,000 in north Fulton County, roughly twenty-five miles north of downtown Atlanta along the GA 400 corridor. Founded in the 1850s, it spent most of its history as a small north Georgia town before the arrival of GA 400 and the growth of the technology and corporate corridor transformed it into one of the Southeast's densest concentrations of office employment. More than half the city's total acreage sits beneath tree canopy, and it maintains over thirty parks and 775 acres of green space. That combination — heavy hardwood canopy outdoors and a population that spends most of its waking hours inside sealed modern buildings — gives Alpharetta an allergen profile in which indoor exposure matters unusually much relative to the seasonal pollen that dominates most conversations.
Dust mites are microscopic arachnids that feed on shed human skin and colonize mattresses, pillows, upholstered furniture, and carpet. They require relative humidity above roughly fifty percent and are most productive between about 68 and 77 degrees Fahrenheit — conditions that a climate-controlled home maintains continuously. In Alpharetta's humid subtropical climate, combined with large newer homes built to modern airtightness standards, those conditions persist year-round. Tight building envelopes conserve energy by exchanging very little air with the outdoors, which also means indoor humidity and allergen accumulate rather than dissipating. Older, leakier construction ventilated itself inefficiently but continuously; contemporary construction does not. The practical consequence is an allergen with no season at all, in a city where residents spend the overwhelming majority of their time indoors.
The GA 400 corridor through Alpharetta hosts an exceptional density of technology, financial services, and corporate offices — the reason the area is sometimes called the technology hub of the Southeast. For many residents the daily pattern runs from a sealed home to a sealed vehicle to a sealed office and back again, with minimal outdoor time on weekdays. Office buildings add their own exposure: centrally managed HVAC that occupants cannot adjust, extensive wall-to-wall carpet, and filtration standards set by building operators. Symptoms that track the workweek rather than the pollen calendar frequently point to the building rather than to the season.
Wills Park spans 120 acres and includes a sixty-acre equestrian show facility widely regarded as among the finest in the Southeast — a regional marquee venue that genuinely distinguishes Alpharetta from comparable suburban cities. For allergy purposes this introduces exposures uncommon in suburban settings. Horse dander is a well-established allergen. Hay, straw, and stored feed harbor storage mites, close relatives of house dust mites that live in grain and forage and cross-react with them immunologically. Stable environments also carry elevated mold loads from damp bedding and hay. Riders, facility staff, and families in equestrian programs encounter a genuinely different allergen set than their neighbors.
Roughly twelve miles of the Big Creek Greenway run within Alpharetta, part of a regional trail system extending north into Forsyth County. The paved corridor periodically gives way to elevated wooden boardwalks crossing wetlands and marsh, shaded throughout by dense mature hardwood canopy. Ecologically this is a protected bottomland corridor threading through the city: oak, sweetgum, hickory, river birch, sycamore, and green ash produce concentrated spring pollen, and the wetland sections sustain fungal spore production through the warm months well above surrounding upland levels.
With more than half the city shaded, Alpharetta carries substantial mature hardwood cover across established residential neighborhoods and throughout its park and greenway system. Oak dominates as the region's most potent tree allergen, with sweetgum, hickory, and loblolly pine abundant alongside it. Because these species peak within roughly the same late-March-to-April window, spring arrives abruptly rather than gradually. Piedmont red clay underlies the uplands, draining slowly and holding moisture against foundations after heavy thunderstorms.
Alpharetta's combination of large airtight modern homes and a humid subtropical climate sustaining year-round dust mite populations, a corridor workforce spending nearly all its time across two sealed indoor environments, Wills Park's major equestrian facility introducing horse dander and storage mite exposure uncommon in suburbs, twelve miles of bottomland greenway concentrating spring pollen and wetland mold, and canopy over half the city producing a compressed and severe spring peak create an allergy environment distinct from anywhere else in north metro Atlanta. HeyAllergy connects Alpharetta residents with board-certified allergists through telemedicine. Patients receive allergy blood testing, personalized treatment, and HeyPak® sublingual immunotherapy drops custom-formulated for Piedmont and indoor allergens. Treatment starts at $47/month. No needles, no clinic visits, no waitlist.
