7-Day Pollen Forecast for London
Pollen Season in London
London's pollen season is shaped by its mild, damp climate and the abundance of parks, commons, and riverside meadows that blanket the city. Birch trees are the first to trigger symptoms, releasing clouds of pollen from March through late April in Hyde Park, Hampstead Heath, and along the Thames corridor. Grass pollen then dominates from May through late July, reaching peak concentrations during warm, breezy afternoons. Urban heat islands in the City and Canary Wharf can extend the season by several days compared to outer suburbs. Mugwort adds a secondary wave for sufferers in August. Rain provides temporary relief but post-storm pollen bursts are common. Hay fever affects roughly one in five Londoners, making the capital one of the UK's most challenging cities for allergy sufferers during the summer months.
- Check the Met Office pollen forecast each morning — London often has higher counts than the national average due to urban heat retention.
- Avoid Richmond Park and Hampstead Heath during peak grass season (June) on dry, windy afternoons when counts reach Very High levels.
- Keep windows closed on the South Bank and in central parks; the river breeze carries significant grass pollen from Surrey meadows upstream.
