UK Pollen Forecast 2025 Reveals Shocking Pollen Surge Across Europe – Are You at Risk?
Pollen Forecast for Europe, Including UK Pollen Forecast, 11–19 March 2025: Recommendations from Allergists and Meteorologists
Europe is experiencing a high level of alder pollen concentration, according to the SILAM (System for Integrated modeLing of Atmospheric coMposition) model forecast for March 2025. The pollen forecast map indicates a significant increase in allergens across central and western Europe, posing a serious challenge for hayfever sufferers. Additionally, data from the UK Met Office provides insights into weather conditions driving pollen spread. Below is an extended hayfever forecast for allergy sufferers from 12 to 19 March 2025.
Analysis of the SILAM Forecast March
High alder pollen concentration (over 500 particles per cubic metre) is observed in Central Europe, including Germany, Poland, Czechia, Slovakia, Austria, and Hungary. In some areas, particularly southern Germany and western Poland, levels reach critical values of up to 1,000 particles/m³.
Moderate levels (50–500 particles/m³) are recorded in the Netherlands, Belgium, France, northern Italy, and eastern Spain.
Low levels (less than 50 particles/m³) are noted in the UK, Scandinavia, the Baltic countries, and southern Italy and Greece.
UK Pollen Forecast and Europe-Wide Outlook for 12–19 March 2025 (Based on UK Met Office Data)
Based on current trends and long-term weather forecasts, the following conditions are expected:
12–13 March: Central Europe maintains warm, dry weather (10–15°C), sustaining high alder pollen levels (500–1,000 particles/m³). The UK and Scandinavia may see rain, reducing pollen concentration to 10–50 particles/m³. Southern Europe (Italy, Spain) will have temperatures of 12–18°C, with moderate pollen levels (50–200 particles/m³).
14–15 March: Weather in Central Europe remains stable (12–16°C), but light rain in some areas (e.g., southern Germany) may temporarily lower pollen to 200–500 particles/m³. The UK will experience heavier rain, dropping pollen levels to minimal values (<10 particles/m³). Southern Europe may see pollen rise to 200–500 particles/m³ due to dry conditions.
16–17 March: Central Europe: temperatures rise to 14–18°C, with alder pollen potentially peaking (up to 1,000 particles/m³) in Poland and Czechia. The UK and Scandinavia: improving weather (8–12°C), with low pollen levels (10–50 particles/m³). Southern Europe: dry weather boosts pollen to 500–1,000 particles/m³ in parts of Spain and Italy.
18–19 March: Central Europe: light rain (15–17°C) may reduce pollen to 100–500 particles/m³. The UK: variable cloud cover, with pollen remaining low (<50 particles/m³). Southern Europe: warm weather (16–20°C) sustains high pollen levels (500–1,000 particles/m³), especially in coastal areas.
Recommendations for Hayfever Sufferers
High alder pollen levels pose a significant risk to those with hayfever. Follow these tips for 12–19 March:
Limit outdoor time, especially during morning hours (5:00–10:00), when pollen peaks. This is particularly important on 16–17 March in Central and Southern Europe.
Use protective measures: Wear sunglasses and a mask, and rinse your nose and eyes with saline solution after returning home.
Take medication: Start or continue antihistamines or nasal sprays. During peak levels (16–17 March), consult a doctor for stronger treatment if needed.
Keep windows closed in homes and cars, especially in Central and Southern Europe from 12 to 17 March.
Monitor symptoms: Seek medical help immediately if breathing becomes difficult or hayfever symptoms worsen.
In high-pollen areas (Central and Southern Europe), plan outdoor activities for evenings or rainy days (e.g., 14–15 March).
Check local hayfever forecast updates, as the alder season may vary by region.
Stay vigilant about your health and prepare for potential allergic reactions.
