We supply and produce the pollen forecast for the UK in conjunction with the Met Office.

Weekly pollen forecast and summary

Forecast for 26th January to 1st February 2021: Fungal spores moderate to high for penicillium. Hazel and alder pollen starting, low risk generally.

Grass Pollen Count - None

Grass pollen season is now over and will resume again in late Spring 2021. New regional pollen calendars are now available

Tree Pollen Count - Low


Hazel and alder tree pollen are airborne but the general risk will remain low for now as most of the wild trees are only just starting. Ornamental hazel trees are more advanced and may trigger symptoms in susceptible people when very close to these trees.

Fungal Spore Levels - High

Penicillium will continue at a moderate to high risk, the greater risk in milder, damp weather. Leptosphaeria will be airborne in association with wet weather and may trigger symptoms in those susceptible to this type. Visit our fungal spore webpage for more info.

Weed Pollen Count - None

Pollen forecast for weeds with a low green pollen count.

Weed pollen season is now over and will resume again in Spring 2021.

Pollen forecasts are available on a regional basis to cover the whole of the UK including Northern Ireland and the Republic of Ireland. They can also be provided in detail for individual regions.

Daily pollen and spore forecasts are issued from mid-March to early October

Daily pollen forecasts are featured in newspapers, on radio, on television and various web pages.

All the forecasts are based on information from the quality controlled data produced by the National Pollen Monitoring Network, combined with the information from weather forecasts, local vegetation and typography types and information about biological factors and the weather in the preseason period that influences the pollen count.
