Updated: 2/12/2026
In Oslo, the pollen season is relatively short due to the cool climate, typically starting in late May and ending in August. The most common pollen types are birch, grass, and mugwort, which can cause allergic reactions for some individuals.
The city's green spaces, such as parks and forests, contribute to the pollen levels. However, the sea breeze from the Oslofjord can help disperse pollen and reduce its concentration in the city center. Overall, being aware of the local pollen forecast is key to managing allergies in Oslo.
