Pollen forecast

Pollen allergies can have a serious impact on people’s well being.

Pollen forecasts are available on the weather map and provide people with vital information to help reduce the impact of pollen on their health.

Different types of pollen are released throughout the year which can generate hay fever and other allergies. Our pollen forecast can help you manage these symptoms providing pollen counts five days ahead.

Check the pollen count

We manage the only pollen count monitoring network in the UK using information from our network, our weather data and expertise from organisations such as the National Pollen and Aerobiological Unit and PollenUK to produce forecasts that help support allergy and hay fever sufferers through the most difficult time of the year.

The pollen season has now ended and resumes in March 2016.

Pollen season

The pollen count season is normally March to August. However, it can start as early as January and end as late as November.

The pollen season separates into three main sections:

  1. Tree pollen - late March to mid-May.
  2. Grass pollen - mid-May to July.
  3. Weed pollen - end of June to September

Our pollen calendar has a detailed breakdown of the different types of pollen and their peak times within a season.
