Respira
Elm pollen allergy
Elms pollinate at both ends of the year: American elm in late winter, and several introduced species again in the fall. That second season catches people who associate tree pollen with spring.
Season
February to April, with a second autumn release from some species.
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. The autumn-flowering species can overlap with ragweed, making the two hard to separate by timing alone.
Where it occurs
Across the eastern and central United States, and widely planted in cities.
Track it day by day
Respira reports elm 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.
