England Braces for Worst Hay Fever Day This Week
3 Jul
Summary
- Very high pollen levels are forecasted for 16 county-level areas in England on Friday.
- Warm, dry, and breezy conditions are ideal for pollen release and spread.
- Scotland and Northern Ireland are expected to experience lower pollen levels.

Millions of allergy sufferers are being alerted to a significant increase in pollen levels. On Friday, the Met Office has predicted "very high" grass pollen concentrations across 16 county-level areas in England, including the East of England and London and the South East. High pollen levels are also anticipated for much of England and Wales.
These elevated counts are attributed to the current warm, dry, and settled weather patterns. Light winds facilitate pollen release, while the lack of rainfall prevents it from being washed away, intensifying symptoms for hay fever sufferers. These conditions are considered optimal for pollen to spread efficiently.
While Saturday may see some slight easing in certain areas, high grass pollen is still expected across central, eastern, and southern England. Northern regions of the UK are forecast to experience milder conditions, with Scotland largely remaining a low-risk area and Northern Ireland anticipating mostly moderate pollen levels throughout the weekend.
