Heat Alert: England Swelters, Wildlife Struggles
29 Jul
Summary
- Amber heat health alert issued for eastern England due to rising temperatures.
- Reservoir levels are significantly below average, impacting water availability.
- Extreme weather affects bird populations in mixed ways, with chicks struggling.

Eastern England is currently under an amber heat health alert, with temperatures predicted to reach 34C (93F) within 24 hours from Wednesday 09:00 BST. This alert signals potential significant impacts on health and social care services, including an expected rise in mortality, particularly among vulnerable age groups and those with pre-existing conditions.
Reservoir levels across the region are notably below average, with Anglian Water sites around 75% capacity. This has led to widespread hosepipe bans, affecting residents like Jessica Southwell in Essex, who understands the restrictions and uses a watering can. Conversely, Lowestoft in Suffolk, supplied by a different water company, is not under a ban, though residents still feel a need for water conservation.
Despite the general restrictions, some exemptions exist for health, safety, and animal welfare. Ninety-five-year-old Maisie Pettitt from Suffolk, for example, received permission to use a hosepipe for her garden due to her age and vulnerability, preventing potential falls.
The extreme heat also presents a mixed picture for bird populations, according to the British Trust for Ornithology. While increased temperatures can boost insect visibility for nesting birds, young birds struggle with thermoregulation in confined spaces like nest boxes, where temperatures have been recorded at 35C (95F). The timing of heatwaves and cold snaps can disproportionately affect different species.
