Respira
Oak pollen allergy
Oak is one of the most widespread tree allergens in the United States. It is not the most potent grain by weight, but there is so much of it, over so much of the country, that it dominates spring counts from Georgia to New Jersey — and it is what leaves cars yellow in April.
Season
March to May, earlier in the South.
Pollen seasons shift with latitude and elevation — the same species can start six weeks apart in Texas and Minnesota — so treat these months as the shape of the year rather than a date to plan around. Respira shows the level measured for your own location each day.
Symptoms commonly associated with it
Associated with spring rhinitis and conjunctivitis. Because oak season overlaps with several other trees, it can be hard to tell apart from birch or maple without testing.
Where it occurs
Across the eastern half of the country and much of the West Coast. Especially heavy in the Southeast, the mid-Atlantic and parts of Texas.
Track it day by day
Respira reports oak pollen for your location every day, alongside the other ten species measured across the United States, air quality on the EPA scale, and a symptom diary you can export for your allergist.
