Pollen forecast

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

Summary and Weekly Synopsis

A high spore risk during the unseasonally mild weather then decreasing to moderate mid-week. Pollen risk remaining low.

This forecast was last updated on 17th October 2014.

Tree Pollen - Low

The tree pollen risk will remain low until the hazel trees start flowering from late December or January.

 

 

Grass Pollen - Low

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

 

 

Fungal Spore - High

As we will experience some very mild and humid weather, initially the risk will be high in the south and central regions. During the working week the risk will decrease to low to moderate levels as colder weather moves in. The lowest risk will be in the northern regions but even the most northern areas will have a moderate risk during the mildest weather. Penicillium basidiospores sporobolomyces tilletiopsis and Cladosporium will be airborne this week.

 

 

Weed Pollen - Low


The weed pollen season is in decline and the counts will remain low.

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.
