Ostrava, Czechia has a temperate climate with four distinct seasons. Spring, from March to May, is when pollen season starts, with tree pollen being the most prevalent. Summer, from June to August, is generally warm and humid, with grass pollen prevalent.
Autumn, from September to November, is cooler and dryer, with little to no pollen. Winter, from December to February, is cold and snowy, with no pollen activity.
The city's climate is influenced by its location in the industrial region of Moravia-Silesia, with occasional air pollution from nearby industries. However, green spaces, parks, and forests around the city help to improve air quality and provide a refuge for those with allergies.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
