Groningen, in the Netherlands, has a temperate maritime climate with cool summers and mild winters. Rain is common throughout the year.
Pollen seasons in Groningen are influenced by the local climate and vegetation. Tree pollen is prevalent in spring, grass pollen in late spring and summer, and weed pollen in late summer and early fall.
The Netherlands is known for its flat landscape and high water table, which can lead to a high pollen count, particularly after windy or dry weather. However, the country's maritime climate also means that rain can quickly clear the air of pollen.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
