Pollen forecast

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

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 forecast is based on this detailed breakdown of the different types of pollen and their peak times within a season.

The pollen count monitoring network combines Met Office weather data with expertise from organisations such as the National Pollen and Aerobiological Unit and PollenUK to produce pollen forecasts for 5 days ahead across the whole of the UK.

The above weather map shows you exactly how pollen is behaving in your area right now, by combining official Met Office data, social activity and live pollen alerts from fellow sufferers.
