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

Weekly pollen forecast and summary

Forecast for 25th September to 1st October 2021: Pollen: low; Spores: high

Grass Pollen Count - Low

Grass pollen in terminal decline with only a low risk. New regional pollen calendars are now available

Tree Pollen Count - Low

Pollen forecast for trees with a low green pollen count.

Tree pollen at a very low risk for the most part but Atlas Cedar trees will pose a local risk to a small minority of people.

Fungal Spore Levels - High

Pollen forecast for spores with a high orange pollen count.

With warm weather continuing to hold, the spore risk will continue at a high level but cooler, showery weather in the new week will reduce the risk in many areas. Penicillium will continue in peak season, often at a high risk. Alternaria, Cladosporium, Basidiospores (from mushrooms/toadstools) and Epicoccum will rise to a high risk during warm, dry weather. Showers will bring Leptosphaeria and allies to many areas from Monday. Visit our fungal spore webpage for more info.

Weed Pollen Count - Low

Weed pollen is now in terminal decline and the risk will be low.

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.
