What to do

High grass pollen risk today. You may feel it before the day looks obviously bad.

  • Take your usual hay fever precautions before heading out.
  • Sunglasses and a quick clothes change after being outside may help.
  • Some breeze may carry pollen around locally, especially near parks, verges, and gardens.
  • Little rain is expected, so pollen is less likely to be washed out of the air.
Antihistamine?Consider your usual antihistamine early.
