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

Weekly pollen forecast and summary

Forecast for 11th to 17th July 2020: Pollen: Moderate to high risk for Grass. Weed pollen moderate. Fungal spores moderate to high.

Grass Pollen Count - High

Pollen forecast for grass with a high orange pollen count.

Grass pollen now in decline but a moderate to high risk can still be expected in many regions for the next week or two during any warm dry weather.  New regional pollen calendars are now available

Tree Pollen Count - Low

 

The tree pollen risk will be low for most types but sweet chestnut trees are flowering in southern/central UK and lime pollen is still affecting north-western areas and Northern Ireland, so a localised moderate risk can be expected near these tree types during good weather. These types affect a small minority of people.

Fungal Spore Levels - High

A wide range of fungal spore types are now in season, with a high risk in England and Wales during warm weather. Dry weather will see a risk from Alternaria, Cladosporium, Epicoccum and damp/humid conditions will allow Didymella and others to be dispersed. Visit our fungal spore webpage for more info.

Weed Pollen Count - Moderate

The weed pollen risk will continue to be moderate during good weather but any rainfall will reduce the risk where it occurs. The main type in flower being nettle.

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.
