Pollen allergies affect many people in Heraklion, Greece. This type of allergy occurs when the body reacts to pollen from trees, grasses, and weeds.
Trees produce pollen from February to May in Heraklion. Olive trees, which are common in Crete, release pollen from late March to early May. This is the main tree pollen season in Heraklion.
Grasses and weeds produce pollen from May to September. This is a longer pollen season, but the pollen counts are usually lower than during the tree pollen season. The highest pollen counts are usually in June and July.
Pollen counts are usually highest on hot, dry, and windy days. They are usually lower on cool, rainy, and cloudy days. It's a good idea to check the pollen forecast before planning outdoor activities in Heraklion, especially if you have pollen allergies.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
