Maple pollen allergy
Maples flower very early — often before their leaves are out, and before most people think of pollen season as having started. Box elder, a maple despite the name, is the one that produces the most allergenic pollen of the group.
Season
February to May, depending on species and latitude.
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 rhinitis and conjunctivitis. Because maple season opens the year in many regions, symptoms can arrive weeks before people expect them.
Where it occurs
Throughout the eastern and central United States, and widely planted as a street tree well outside its native range.
Track it day by day
Respira reports maple 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.
