Pollen forecast

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

This year the pollen forecast is sponsored by Benadryl®

Different types of pollen are released throughout the year which can generate  hayfever and other allergies. These symptoms can have a serious impact on the well-being of some people.

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.

Benadryl's® Social Pollen Count 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.

How can the Met Office help?

We manage the only pollen count monitoring network in the UK and produce pollen forecasts up to five days ahead. We use information from our network, our weather data and expertise from organisations such as the National Pollen and Aerobiological Unit at the University of Worcester and PollenUK to produce forecasts which are designed to help support allergy and hay fever sufferers through the most difficult time of the year.

Pollen diary

As part of an important Europe-wide study, hay fever sufferers are recording their symptoms online through the European Aeroallergen Network (EAN) Patient's Hayfever Diary.

Document your symptoms and compare them with concentrations of pollen in the air, to help identify which pollen you are allergic to, look back at pollen levels from previous seasons and read the latest pollen news. This is a long-term study that will significantly aid research into pollen and hay fever.
