Windy does not provide actual pollen measurements – for those you need official pollen services. This page puts the weather in context: wind, rain and dry spells affect how much pollen stays in the air. Below you will find the matching maps.

Official pollen data gives load levels by pollen type – we do not have a dedicated map for that. Instead, wind, rain, temperature and humidity radar provide the weather background: wind transports pollen, rain washes it from the air, dry warmth promotes release.
Open the matching maps at the top of this page and zoom to your region. When heat rises after several dry days, pollen load often increases too – especially in early summer with grass pollen.
Strong wind carries pollen over long distances. Light wind leaves it concentrated locally in the air.
After rain the air is often clearer. Dry, sunny days after warm spells promote pollen release.
Many pollen types peak in the morning and midday – then check the wind and rain maps.
Hazel and alder often start in late winter, birch follows in spring. Grass pollen dominates May through July. Ragweed can reach high local values from August in warm summers – especially in the Rhine-Main area and southern Germany.
The map does not replace a pollen monitoring station. It helps you understand why load rises or falls on a given day: often brief relief after thunderstorms, sometimes long-range transport under high pressure and dry wind from other regions.
Keep windows closed in the morning and midday when dry wind blows and no rain is forecast. Plan walks for the evening. Ventilate after rain showers while it stays dry.
Combine the map with weather alerts for thunderstorms and heavy rain: sudden weather changes can briefly improve pollen conditions but also mobilize dust and mold spores.
For load levels by pollen type you need official services: Germany's national weather service publishes pollen forecasts; the NINA warning app also covers severe weather that can change pollen conditions at short notice.
Use our wind and rain maps for weather context – and official sources for concrete pollen values in your region.
