The Met Office has extended its urgent heatwave warning, projecting extreme temperatures of up to 38°C in parts of the UK this week. The sharp rise in temperature is expected from Monday, June 22, and is set to increase further, with the possibility of breaking the current June record of 35.6°C recorded in Southampton in 1976 and Camden Square in 1957.
Record-Breaking Heat Expected
Highs of 37°C are forecast for southern England on Tuesday, while Wednesday and Thursday could see temperatures reach 38°C. The usual relief of cooler nights will be absent, as the Met Office warns of widespread tropical nights where temperatures do not drop below 20°C. This combination of heat and humidity is expected to cause significant impacts across society.
Met Office Warning and Expert Comments
Met Office Deputy Chief Forecaster Tom Crabtree stated: "The forecast heatwave is developing into an impactful severe weather event, with record-breaking June temperatures and very high humidity. The combination of heat and humidity will be oppressive and bring impacts across society from public health and infrastructure, to power and water supplies."
He added: "As well as very high daytime temperatures, there will be consecutive nights where temperatures do not drop below 20°C, which is called a Tropical Night. This will make it very hard for people to recover from the daytime heat, exacerbating the heat stress impacts."
Health Advice and Precautions
The Met Office has issued guidance on how to spot heatstroke and what to do if suffering. They advise drinking plenty of water, seeking shade between 11am and 3pm, closing curtains in rooms that face the sun, and looking out for one another. The amber weather warning remains in place for many areas, with potential impacts on public health, infrastructure, and power and water supplies.
Previous Warnings and Extended Impact
The Daily Express previously reported a heat "intensify" warning issued by Met Office Deputy Chief Forecaster Greg Wolverson. He said: "While heatwave criteria will be met for some in the south and southeast of England over the weekend, with temperatures into the low 30s Celsius possible, the warmth will expand and intensify at the start of next week, which, coupled with high temperatures overnight, leads to potential impacts."
Wolverson continued: "Temperatures will peak around the mid-30s Celsius on Monday and Tuesday. The humidity will also mean this feels close, warmer and more uncomfortable for many. Tropical nights – where the temperature doesn’t drop below 20°C are also likely for some."
