June 2025 Allergy Forecast for Europe: Country-by-Country 🌿
June 2025: Grass pollen peaks in Europe’s heat. Humid rains boost mold. Watch June 12–14 for high pollen.
Overview Pollen of June 2025 Allergy Trends
June 2025 in Europe brings warm temperatures (18–30°C) and increasing humidity, creating ideal conditions for pollen and mold, the primary allergy triggers. Grass pollen dominates across the continent, with tree pollen (birch, oak) lingering in northern regions and ragweed emerging in southern areas. Mold spores thrive after rain showers, expected around June 15–17, particularly in humid coastal and river regions.
Dry, sunny spells (June 12–14, 20–22) drive high pollen counts, while warm winds spread allergens further. Northern Europe sees milder temperatures, but humidity amplifies mold risks. Southern Europe faces hotter, drier conditions, intensifying pollen. Stock up on medications and check air filters early to avoid summer travel disruptions. Below is a country-by-country Pollen forecast with high-risk allergens, symptom management tips, and weather-based advice for June. 🌞
