Gardeners are being urged to leave a tray of water outside this weekend as temperatures are forecast to reach and exceed 30°C across the UK in the coming days. With heatwave conditions expected, experts say providing water can help wildlife thrive during the warm weather.
Heatwave Alert and Temperature Forecast
The Met Office has warned that temperatures could peak at 34°C, and the UK may experience another heatwave at the start of next week. In response, the UK Health Security Agency (UKHSA) has issued an amber heat-health alert for the East of England, London, South East, and South West, along with a less severe yellow alert for the East Midlands and West Midlands.
Hot, dry conditions with little rain can be detrimental to pollinators like bees, as well as birds, hedgehogs, frogs, and other wildlife. Periods of low rainfall affect creatures that rely on fresh drinking water during the sunnier months.
Impact on Bumblebees and Birds
Bumblebees have a furry coat that protects them in the UK's moderate climate, but the WWF warns that as summers get warmer, bumblebee populations could face increased pressure. Birds also need fresh water to stay cool, maintain strength, and avoid dehydration. Gardeners are therefore asked to leave a tray of water in their gardens to help these creatures endure the drought-like conditions.
Paul De Ornellas, Chief Adviser for Wildlife at WWF, explained: "Bumblebees are crucial for pollinating crops, fruits, and plants. They are vital for a healthy environment and food production. Unfortunately, they are in decline due to habitat loss, pesticides, and pollution, worsened by climate change. As temperatures rise, bumblebees move north, but some species may have nowhere to go."
He added: "Bumblebees have a furry coat and prefer cooler climates, as they can overheat and become unable to fly or forage. Extreme heat also causes flowers to wilt, reducing nectar and pollen. Place a shallow tray of water with pebbles or bark for bees to rest on while drinking. Planting flowers in shaded areas also helps."
Wildlife Trusts Advice
The Wildlife Trusts note: "Water is essential for wildlife, not just for drinking. Amphibians like newts, frogs, and toads use water as shelter and breeding grounds. Butterflies get minerals from muddy water, and birds bathe to remove parasites. During hot summer weather, ensure plenty of water for animals and birds."
Met Office Forecast Details
Met Office Chief Forecaster Steve Ramsdale said: "From the end of the week, a marked north-south split develops. High pressure over mainland Europe brings warm, humid air to southern and eastern areas, while lower pressure in the northwest keeps conditions changeable."
Deputy Chief Forecaster Gregory Wolverson added: "Some areas in the south and southeast may meet heatwave criteria over the weekend, with temperatures reaching the low 30s. Headline maximum temperatures: 32°C on Friday in East Anglia, 28°C on Saturday, 32°C on Sunday in the south and southeast, and potential for 34°C on Monday. There is a 40% chance of exceeding the UK June maximum temperature record of 35.6°C set in 1957 and 1976."
He noted: "While temperatures may be high, we might not see wall-to-wall sunshine due to cloud cover. High humidity may feel oppressive, and there is a chance of thunderstorms with heavy downpours."
