Pollen forecast

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

Summary and Weekly Synopsis

The fungal spore risk will remain high to very high across most of the country. Generally the pollen risk will be low, but there is a moderate to high risk from cedar trees during warm dry weather.

This forecast was last updated on 12th September 2014.

Tree Pollen - Moderate

Cedar trees are now in season and the risk will be moderate to high on warm dry days.











Grass Pollen - Low

The grass pollen counts will remain low for the rest of the year.















Fungal Spore - High

Fungal spores are still in the peak of their season so the risk will continue to be high. Variable weather will give a mixed risk with cool weather reducing the spore risk at times while warm humid weather will mean a very high risk in places.



















Weed Pollen - Low

The nettle season is now drawing to a close so generally the risk will be low. There will still be some nettle and other weed pollen airborne especially on particularly warm and sunny days which may cause some symptoms for some.










Other information

Oilseed rape (Brassica napus) pollen can cause hay fever in a small number of sufferers but Volatile Organic Compounds (VOCs) given off by the crop can cause irritation of the upper respiratory tract and eyes in some people in close proximity to the crop.
