Respira
Juniper and cedar pollen allergy
Mountain cedar — a juniper, despite the name — is the reason central Texas has a pollen season in December and January, when most of the country has none. Local counts during a cedar event are among the highest recorded for any pollen anywhere in the United States.
Season
December to February for mountain cedar; spring elsewhere.
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 intense rhinitis and conjunctivitis during release events, which can be short and severe rather than a long gentle season.
Where it occurs
Central Texas above all, plus the Southwest, the Great Basin and the Rocky Mountain states. Junipers are also very widely planted as landscaping across the West.
Track it day by day
Respira reports juniper and cedar 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.
