Weekly pollen and fungal spore forecast summary
Forecast to Friday 5th June 2026, for West Midlands forecast region: Pollen: grass pollen moderate to high; Spores: Moderate.
Grass Pollen Count - High
The hot weather prompted some flowering of main season grasses and so there is the risk of high on warm, dry sunny days but the bulk of the grasses have yet to flower and the peak of the season is expected to occur in the middle fortnight of June, weather permitting.
Tree Pollen Count - Low
Tree pollen all very low.
Fungal Spore Levels - High
Cladosporium now at high risk on warm, dry days. Pleospora at a moderate risk, but soon in decline. Leptosphaeria and allies will increase during high humidity and in association with rain.
Weed Pollen Count - High
Nettle pollen is now in flower, along with plantain and dock, giving a moderate to high risk to those affected by weed pollen.
