7-Day Pollen Forecast for Stockholm
Pollen Season in Stockholm
Stockholm's pollen season is compressed into a shorter but often intense window due to the Nordic climate. The city is surrounded by boreal forest dominated by birch, alder, and pine — birch pollen is the primary allergen, typically peaking in early-to-mid May when the entire Swedish birch forest releases simultaneously following winter dormancy. Because the season is brief, counts can reach Very High for several consecutive days during peak bloom. The Stockholm Archipelago and Ekoparken city forest are major source areas. Grass pollen from parks and roadsides follows in June, though counts are generally lower than in Central Europe. The long spring days and cool temperatures extend morning pollen dispersal later than in southern cities. Approximately 25% of Swedes have hay fever, with birch allergy being the most prevalent type in Scandinavia.
- Birch pollen in Stockholm can go from Low to Very High within 48 hours in early May — check forecasts daily during this transition period.
- The Djurgården island and Lidingö have dense birch woodland; sensitive individuals should plan alternative activities during peak birch bloom.
- Cross-reactivity between birch pollen and certain foods (apples, hazelnuts, carrots) can cause oral allergy syndrome — be aware during May.
