Respira
Ash pollen allergy
Ash flowers in early spring, usually alongside oak and maple. Its pollen is closely related to that of olive and privet, which is why people sensitised to one often react to the others.
Season
March to May.
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. Cross-reactivity within the olive family means a reaction to ash can hint at a reaction to olive in regions where both occur.
Where it occurs
Across most of the country, though the emerald ash borer has removed a great many mature ash trees from the Midwest and Northeast.
Track it day by day
Respira reports ash 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.
