In Andorra, pollen seasons start in March and last until August. Trees like oak, birch, and hazel release pollen, causing allergic reactions.
Grasses release pollen in May and June, making symptoms worse. High pollen levels occur when temperatures rise and humidity is low.
Pollen counts are highest between 5am and 10am. They decrease at night, when temperatures cool and humidity increases.
Andorra's mountainous terrain affects pollen distribution. Pollen concentrations vary across regions, with higher levels in valleys and lower levels at higher elevations.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
