Respira
Grass pollen allergy
Grass is the most common cause of seasonal allergy worldwide, and the United States is no exception. It covers hundreds of species — lawn grasses, pasture, cereals and roadside weeds — whose pollen is released from late spring into summer, and in the warm South for much of the year.
Season
May to July in most of the country; nearly year-round in the Deep 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 rhinitis, conjunctivitis and, in some people, respiratory symptoms. Intensity generally follows the concentration of pollen in the air.
Where it occurs
Everywhere. The season is longest in the South and shortest in the far North.
Track it day by day
Respira reports grass 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.
