Summary and Weekly Synopsis
Low amounts of early tree pollen will continue to be airborne. Start preparing for the birch pollen season likely to start in late March.
Tree Pollen - Low
Start preparing for the birch pollen season now if you suffer from birch pollen which is likely to start in late March in the South of the UK. Alder and hazel trees are still emitting pollen but the risk has decreased to low. There are also small amounts of Elm and Ash pollen around.
Grass Pollen - Low
The grass pollen season will start in May.
Fungal Spore - Low
All spore types are at currently at low levels. However, the air won't be entirely spore free as there will continue to be some penicillium and aspergillus spores airborne that may trigger symptoms in some people. Pleospora (a relative of Alternaria) is now increasing and may trigger some symptoms in those susceptible to these types.

Weed Pollen - Low
The weed pollen season will start 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.
