Tree Pollen - Low

The early part of the tree pollen season is likely to start in the South and Central regions of the UK in mid-January with Hazel first followed later in the month with Alder. Northern regions will start to be affected in late January or early February depending on the weather at the time.

Grass Pollen - Low

The grass pollen counts will remain low until the late Spring.

Fungal Spore - Moderate

The fungal spore levels will continue to rise to moderate at times for basidiospores and penicillium/aspergillus types. Central and southern UK will be the main areas affected. The very mild autumn and late fall of leaves has extended the season this year. Some spore sufferers will continue to have some symptoms throughout much of the Winter since penicillium tends to have a second peak in January and February.
