7-Day Pollen Forecast for Madrid
Pollen Season in Madrid
Madrid has one of the most intense grass pollen seasons in Europe, driven by the vast Castilian plateau's cereal crops and grasslands that surround the capital. Rye and other grasses release enormous quantities of pollen from late April through June, frequently pushing counts to Very High for weeks at a stretch. The dry, windy conditions of the Meseta amplify dispersal — southerly winds sweeping across Toledo and Ávila provinces can deliver massive pollen surges to the city. Olive pollen from central Spain adds to the burden in May. Retiro Park and Casa de Campo contain significant birch and oak that contribute to the spring tree pollen load. Madrid's low rainfall during the season means little natural wash-out, prolonging high-count days. The city has one of Europe's highest hay fever prevalence rates, particularly for grass allergy.
- Madrid's grass season is among Europe's most severe — start medication well before the end of April.
- Stay indoors between 12:00 and 17:00 on sunny, breezy days in May and June when grass counts peak.
- Southerly and westerly winds from the Castilian plateau bring the worst surges; check wind forecasts alongside pollen levels.
