Pollen forecast

We produce and supply the pollen forecasts for the UK in conjunction with the Met Office. This forecast was last updated on 14 September 2018.

Summary and Weekly Synopsis

Forecast for 15 – 21 September. Fungal spores moderate to high. Pollen low.

Tree Pollen - Low

The tree pollen risk is currently very low for most types. However, for those affected by cedar (Cedrus) trees, this pollen type will be increasing to a locally high risk. 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 - High

Fungal spores will be at moderate levels in Scotland, the far north of England and Northern Ireland and high elsewhere. Cladosporium and Alternaria remain in the air but the seasons are now in decline. Other types of note include Epicoccum, Basidiospores (from mushrooms and toadstools), Aspergillus and Penicillium.

 

 

Weed Pollen - Low

The weed pollen risk will be low, with small amounts of nettle family (Urticaceae) pollen in the air.

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.
