Pollen forecast

We produce and supply the pollen forecasts for the UK in conjunction with the Met Office. This forecast was last updated on 8 October 2018

Summary and Weekly Synopsis

6-12 October: Fungal spore risk generally moderate but low in Scotland. Pollen risk very low.

Tree Pollen - Low

The tree pollen risk is currently very low for most types. However, for those affected by cedar (Cedrus) trees, the pollen risk will increase to locally high during dry windy weather. Only a small minority of people in the UK are affected by this type.

Grass Pollen - Low

The grass pollen season is finished with all regions now at very low levels.


Fungal Spore - Moderate

Fungal spores will be at low to moderate levels in England, Northern Ireland and Wales. Basidiospores (from mushrooms and toadstools)

Aspergillus and Penicillium are currently airborne and most likely to be triggering symptoms. Alternaria and Cladosporium are now at low risk.



Weed Pollen - Low

The weed pollen risk is very low and will remain that way until next Spring.

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.
