What to do

Very high tree pollen risk today. Make this a take-action day if hay fever affects you.

• Keep windows closed when you can, especially morning and evening.
• Avoid mowing, parks, and drying washing outside.
• Wind is likely to move pollen around more than usual, so symptoms can show up away from obvious green spaces.
• Rain should help wash some pollen out of the air, although levels can still rise again when it dries out.
