We produce and supply the pollen forecasts for the UK in conjunction with the Met Office.
Summary and Weekly Synopsis
Peak period for the early Spring trees of Alder and Hazel - expect localized high risk. All other allergenic pollen types remain low.
This forecast was last updated on 7th March 2014.
Tree Pollen - High
There will be a localized high risk for Alder pollen mainly in southern and central regions of the UK. Hazel pollen is also at its peak across the country but this type rarely exceeds the moderate category of risk. The week ahead will have plenty of dry weather to allow pollen dispersal. The risk in the far North of England and Scotland will be mainly low due to fewer sources and unsettled weather at times.
Grass Pollen - Low
The grass pollen risk is currently very low. The grass pollen season will start in May
Fungal Spore - Low
Fungal spores will be low during this forecast period.
Weed Pollen - Low
The weed pollen risk remains very low. Weed pollen emissions usually peak in the summer.
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.
