Beyond today’s pollen
What this forecast doesn’t measure, and when to get help.
No mold level
Google’s index covers tree, grass and weed pollen only, so there is no mold level for Durham on this page. The National Allergy Bureau publishes pollen and mold counts measured at its stations. Our guides cover common molds such as Alternaria, Cladosporium and Aspergillus.
No indoor allergens
The forecast doesn’t cover allergens indoors either: dust mites, cockroaches, mice, cats and dogs. Our guides explain each one, starting with dust mites and cats.
Asthma in Durham
An estimated 11.2% of adults in the city of Durham have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 9.8% to 12.6%). It is a statistical estimate from national survey data, not a count.
Allergists in the Durham area
21 allergists enrolled in Medicare practice in the Durham area: 3.36 for every 100,000 people, more than the 1.22 across the US. The count doesn’t show how soon you can get an appointment. See the doctors listed in the Durham area, or how every state and metro compares.

Durham’s pollen seasons
The geography, climate and plants behind each season here, with a source for every fact.
The Duke Forest covers more than 7,000 acres in Durham, Orange and Alamance counties.2 Pine is its most prevalent cover type, and loblolly, shortleaf and Virginia pine are the most common pines there.3 Oak-hickory is the most widespread of its upland hardwood types, with white, northern red, black and scarlet oaks and several hickory species among the most common overstory trees.3
In North Carolina, the tree pollen season typically spans February to May.4 Pines release their pollen between March and April, at the same time as hardwoods such as oaks and hickories.4 Winters at the Raleigh-Durham airport average about 44 °F.1
Common ragweed, native to most of North America, is listed for North Carolina in the state extension service’s plant database.5 Its male flowers release copious amounts of pollen in late summer and fall, and the wind disperses it.5
