Summary and Weekly Synopsis
Moderate tree pollen for hazel and alder. Still some spores triggering a few symptoms in some people.
Tree Pollen - Moderate
Alder tree pollen is now in peak season with a moderate (and locally high) risk on dry days in the south and central parts of the country. Hazel is still producing pollen in moderate amounts too. The risk will be low during very cold days which are forecast for the week ahead.
Grass Pollen - Low
The grass pollen season will start again in the Spring.
Fungal Spore - Moderate
Aspergillus and Penicillium spores will continue to trigger symptoms occasionally. Other spore types will remain low.
Weed Pollen - Low
The weed pollen season will start again in the Spring.
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.
