In Planá, Czechia, pollen seasons vary by tree and plant type. Birch trees produce pollen from late March to early April. Grasses pollinate from May to July.
Trees like oak, beech, and hornbeam release pollen from late April to early May. Weeds like ragweed and nettle pollinate from July to September.
Pollen counts are usually highest on warm, sunny days. Rain and wind can lower pollen counts. Pollen travels far on windy days, causing issues.
Avoid outdoor activities during peak pollen hours, typically between 5am and 10am. Stay indoors with windows closed to reduce pollen exposure. Use air purifiers to filter pollen.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
