Real-time pollen data for Brookhaven — updated daily.
The first significant tree pollen of Brookhaven's year, releasing weeks before oak and well before the visible pine film appears. Both are genuinely allergenic and both are routinely overlooked because they arrive before people expect pollen season to begin. Residents whose symptoms start in February are frequently reacting to elm and maple while attributing it to oak or pine.
Oak is Brookhaven's dominant tree allergen. White oak, red oak, water oak, willow oak, and post oak occur across mature intown neighborhoods and the creek corridor. Oak grains are microscopic and remain airborne for hours, penetrating deep into the airways. Established canopy in older neighborhoods produces substantially more pollen than younger suburban growth.
River birch lines North Fork Peachtree Creek and begins producing early in the season. Sycamore, box elder, green ash, sweetgum, and red maple occupy the corridor alongside it. Birch is highly allergenic. Cedar and juniper open the season in February.
Loblolly and shortleaf pine produce the visible spring yellow film. Sweetgum is abundant and significantly allergenic. Hickory contributes. Pine grains are large and less efficient at reaching deep airways than oak or birch, but volume makes pine a meaningful irritant.
Brookhaven's distinctive mold pattern. Because the Peachtree Creek watershed is heavily paved, storm peaks run far higher and recede far faster than on less-developed streams, with lower flow in between. Mold therefore spikes in the days following heavy rain rather than remaining elevated through the humid season. Cladosporium and Alternaria lead these pulses, peaking overall in late summer and early fall. Aspergillus and Penicillium are common indoors. Red clay drains slowly, holding water against foundations.
Ragweed is the dominant fall allergen, and Brookhaven's eroding creek banks provide unusually good habitat. Repeated scouring flows strip vegetation and expose bare soil, which pioneer weeds colonize readily. Pigweed, lamb's quarters, nettle, and plantain grow along the corridor, greenway margins, and arterial shoulders. Goldenrod blooms conspicuously alongside but is insect-pollinated and produces little airborne pollen.
Bermuda grass dominates lawns, parks, and athletic fields. Fescue and ryegrass are common on shaded intown lots. Johnson grass grows along greenway margins and roadway shoulders. Brookhaven's dense canopy means proportionally less open turf than lower-density communities.
I-85, Peachtree Road, and Buford Highway carry heavy volume through a compact city. Diesel and fine particulate inflame airway linings and amplify biological allergen reactions. Exposure declines sharply with distance from the roadway, making this highly variable block to block rather than uniform across the city.
Dust mites thrive in the humid subtropical climate. Pet dander is significant. Older intown housing stock carries elevated indoor mold and cockroach allergen risk relative to newer construction, particularly in homes near the creek corridor.
Severity: Low. Trees, grasses, and weeds are dormant. Indoor allergens dominate, with dust mites and pet dander peaking under closed-window heating. Older intown housing near the creek carries elevated indoor mold risk. Cedar and juniper may begin by mid-January. Because Brookhaven's season opens in February rather than March, this is the month to establish preventive treatment — later is too late.
Severity: Moderate. Elm and maple release the year's first significant tree pollen, weeks before oak and before any visible sign of spring. River birch begins along North Fork Peachtree Creek. Cedar and juniper continue. Residents who assume pollen season has not started yet are frequently already reacting.
Severity: Severe. Oak, sweetgum, hickory, and pine peak together across Brookhaven's mature intown canopy. The visible yellow pine film coats surfaces. Creek corridor species compound the load. Established neighborhood oaks produce heavily. Dry, windy afternoons spike counts sharply.
Severity: High. Tree pollen declines as Bermuda grass surges on lawns and parks. Summer thunderstorms arrive, and the flashy watershed begins its characteristic pattern — violent flow spikes followed by rapid recession, producing mold pulses in the days after each significant rain rather than steady elevation. Red clay holds water against foundations. Dust mites rise indoors.
Severity: High. Ragweed begins in August and climbs through September, with eroding creek banks and greenway margins offering abundant disturbed-soil habitat. Storm-driven mold pulses reach their strongest of the year as Alternaria and Cladosporium peak. Heat and humidity remain heavy. Grass continues.
Severity: Moderate to High. Ragweed persists into late October, extended by warm autumns. Goldenrod blooms alongside but is not the cause. Heavy leaf fall from mature intown canopy accumulates along the creek corridor, sustaining Cladosporium and Aspergillus as litter decomposes between storm pulses. Counts drop through November toward the winter lull.
Peachtree Creek behaves unlike the rivers and wetlands elsewhere in metro Atlanta, and understanding why changes how you manage mold here. Its watershed is among the most heavily paved in Georgia, so rainfall does not soak into the ground — it runs off roofs, roads, and parking lots straight into storm drains and into the creek. Long-term USGS monitoring found that peak flows during the largest storms on Peachtree Creek run roughly 30 to 80 percent higher than on comparable less-developed streams, that the creek recedes markedly faster afterward, and that its baseline flow between storms is 25 to 35 percent lower. The corridor spikes violently, then dries out. Practically, this means mold here arrives in sharp pulses in the days following heavy rain rather than sitting elevated all summer the way it does along a wetland or a slow river. If you track your symptoms against the rain gauge rather than the calendar, the pattern usually becomes obvious.
Brookhaven's tree season opens earlier than most people expect, and the culprits are not the ones that get blamed. Elm and maple are among the first significant pollen producers of the year, releasing in February — weeks before oak begins and well before the visible yellow pine film appears. Residents who start feeling symptoms in mid-February and assume it must be oak or pine are misreading their own calendar, and more importantly they are starting preventive medication too late. Antihistamines and nasal steroid sprays need several days to reach full effect. If your season reliably begins in February, your treatment should be established in January. Blood testing will tell you whether elm and maple are actually among your triggers, which determines how early you need to start.
Brookhaven monitors North Fork Peachtree Creek closely enough that city officials use USGS streamflow data to issue flood alerts and close greenway access during storm events. That is a useful signal for allergy patients too. When the creek is in flood, the corridor is depositing sediment and organic debris along its banks, and as those recede and warm over the following days, fungal activity spikes. If you use the Peachtree Creek Greenway regularly, the two or three days after a significant storm are the ones worth skipping — not because the trail is unpleasant, but because that is when the corridor's mold load peaks.
Flashy urban streams cut into their own banks. Repeated violent flow pulses scour channels deeper and strip vegetation, leaving exposed soil and unstable margins along the creek. Bare disturbed ground is exactly what ragweed, pigweed, and other pioneer weeds colonize — they thrive where established vegetation has been removed and cannot compete under intact canopy. The result is that Brookhaven's creek corridor supports more fall weed growth than a stable, well-vegetated stream would. This is a direct downstream consequence of the paving upstream.
Brookhaven is threaded by major arterials — I-85, Peachtree Road, and Buford Highway all carry heavy volume through a relatively compact city. Unlike a regional pollution pattern that affects everyone equally, corridor exposure drops off sharply with distance: a home two blocks off Buford Highway experiences meaningfully less traffic particulate than one facing it. Diesel and fine particulate inflame airway linings and increase reactivity to pollen already present. If you are choosing where to walk, run, or open windows, moving even a few streets away from the arterials makes a measurable difference.
The Buford Highway corridor through Brookhaven is among the most linguistically diverse stretches in the Southeast, home to substantial Latin American, Korean, Chinese, Vietnamese, and Ethiopian communities. For multi-generational households, arranging specialty care can mean coordinating transportation, work schedules, and interpretation all at once for a fifteen-minute appointment. Telemedicine removes the logistics of getting there, which matters most for the frequent, brief follow-up visits that immunotherapy requires over several years.
Because Peachtree Creek is a flashy urban stream. Its watershed is heavily paved, so rain runs off into storm drains instead of soaking into the ground. USGS monitoring found storm peaks on Peachtree Creek run roughly 30 to 80 percent higher than on comparable less-developed streams, that it recedes much faster, and that its baseline flow is 25 to 35 percent lower. The corridor spikes hard and dries quickly, so mold arrives in sharp pulses in the days after heavy rain rather than staying elevated through the season.
Almost certainly not. Elm and maple are the first significant pollen producers of the year and release in February, weeks before oak begins and well before the visible yellow pine film appears. River birch along the creek starts early too. If your season reliably opens in February, preventive antihistamines and nasal sprays should be established in January — they need several days of lead time, so starting when symptoms appear leaves you behind.
February opens the season with elm, maple, and river birch. Late March through April is the severe stretch, when oak, sweetgum, hickory, and pine peak across mature intown canopy. Grass runs May into September. Ragweed peaks August through October, with eroding creek banks providing extra habitat. Mold spikes in pulses after heavy rain year-round.
Not generally — but time it around storms. Brookhaven officials use USGS streamflow data to issue flood alerts and close greenway access during storm events, and the two or three days afterward are when the corridor's mold load peaks as deposited sediment and organic debris warm and dry. On ordinary days the greenway is fine; immediately after significant rain is the window worth skipping.
Flashy flows scour the channel and strip bank vegetation, leaving exposed unstable soil. Bare disturbed ground is exactly what ragweed and pigweed need — they colonize readily where established vegetation has been removed and cannot compete under intact canopy. So the fall weed load along Brookhaven's creek traces back to upstream paving rather than anything in the corridor itself.

Brookhaven is a city of approximately 60,000 in DeKalb County, immediately northeast of Atlanta at an elevation near 1,050 feet. Voters approved incorporation in July 2012 and municipal operations began that December, making Brookhaven DeKalb County's eleventh city and the second formed during the modern wave of municipal incorporations that followed Dunwoody in 2008. Brookhaven is genuinely intown rather than suburban: dense residential neighborhoods with mature canopy, major arterials running through the middle of it, MARTA rail access, and North Fork Peachtree Creek threading its western edge. That creek, and the watershed feeding it, produces an allergen pattern distinct from anywhere else in the metro.
The Peachtree Creek watershed covers roughly 86.6 square miles across the northeast quadrant of metro Atlanta and is among the most heavily developed drainages in Georgia. Piedmont clay soils already absorb water slowly, and extensive impervious surface — roofs, roads, driveways, parking lots — routes rainfall directly into storm drains rather than into the ground. Long-term USGS monitoring comparing Peachtree Creek with less-urbanized watersheds found that peak flows during the largest storms ran roughly 30 to 80 percent higher, that the creek's storm recession was substantially faster, and that its average low flow was 25 to 35 percent lower, attributed to reduced infiltration and the paving of groundwater recharge areas. The corridor therefore spikes hard and dries quickly. For mold, this produces sharp post-storm pulses rather than the sustained elevation found along wetlands, impoundments, or slower rivers elsewhere in Georgia.
The creek's flashiness is well documented and actively managed. USGS operates a streamflow and precipitation station on North Fork Peachtree Creek at Briarwood Road near Brookhaven, and city officials use that data to issue flood alerts and close Peachtree Creek Greenway access during storm events. The September 2009 flooding pushed Peachtree Creek from roughly three feet at base flow to around twenty feet. Downstream, houses built near the creek in the late 1940s and 1950s were physically raised ten feet in the 1970s after repeated flooding — a striking illustration of how watershed development changed flood behavior over a few decades. Brookhaven has commissioned a Watershed Improvement Plan for the North Fork tied to greenway development along the Buford Highway corridor.
Repeated violent flow pulses scour stream channels and strip bank vegetation, leaving exposed soil and unstable margins. Bare, disturbed ground is precisely the habitat that ragweed, pigweed, and other pioneer weeds require and cannot obtain under intact canopy or stable vegetated banks. Brookhaven's creek corridor consequently supports more fall weed growth than a stable stream would — an allergen consequence traceable directly to upstream paving rather than to anything happening in the corridor itself.
Brookhaven's canopy is dominated by oak, but its season opens with species that receive far less attention. Elm and maple are among the first significant pollen producers of the year, releasing in February — weeks ahead of oak and well before the conspicuous yellow pine film arrives. River birch lines the creek corridor and begins early as well. Because the visible markers of spring arrive later than the actual start of pollen season, residents frequently misattribute February symptoms and begin preventive treatment weeks after they needed to.
Brookhaven's older residential neighborhoods carry substantial mature canopy, with large oaks planted generations ago remaining in place across Historic Brookhaven, Brookhaven Heights, Ashford Park, and Drew Valley. Oglethorpe University's campus adds further mature plantings. Pollen output scales with tree size and age, so established intown canopy generates higher counts than younger suburban growth. Piedmont red clay underlies the uplands, draining slowly and holding water against foundations after heavy thunderstorms.
I-85, Peachtree Road, and Buford Highway all carry heavy traffic through a compact city, and the Buford Highway corridor is among the most linguistically and culturally diverse stretches in the Southeast, home to substantial Latin American, Korean, Chinese, Vietnamese, and Ethiopian communities. Traffic particulate inflames airway linings and amplifies pollen reactions, but exposure falls off sharply with distance from the roadway — making this a block-by-block variable rather than a uniform city-wide condition.
Brookhaven's flashy urban watershed producing sharp post-storm mold pulses rather than sustained seasonal elevation, eroding creek banks supporting heavier fall weed growth than stable streams would, an early-opening tree season led by elm and maple that residents routinely misattribute, mature intown canopy generating high spring counts, and arterial corridors creating sharply localized particulate exposure create an allergy environment distinct from anywhere else in metro Atlanta.
