London is expected to reach temperatures of approximately 31 °C on Sunday during the May bank-holiday weekend [1], [2].
This surge in temperature is significant because it could break established May heatwave records for the city. Such early-season extremes place pressure on urban infrastructure, and public health services not typically scaled for summer heat in early May.
The Met Office said the warming is due to a high-pressure system that is pushing unusually warm air across the United Kingdom [3]. This weather pattern has already begun affecting the region. On Saturday, the village of Frittenden in Kent recorded a temperature of 30.5 °C [2].
Forecasts for the capital have varied across different reporting outlets. While the Met Office and other sources project a high of 31 °C [1], [2], some forecasts have suggested the temperature could climb as high as 33 °C [3]. Other reports provided a more conservative estimate of 28 °C for the weekend [4].
Despite the range of predictions, the general consensus among forecasters is that the bank-holiday weekend will be characterized by abnormal warmth. Residents are advised to prepare for the heat as the high-pressure system remains stationary over the region.

The occurrence of 30°C-plus temperatures in May suggests a shift in seasonal norms for the UK. When high-pressure systems trap warm air early in the year, it increases the risk of early-season droughts and heat stress in cities like London, where the 'urban heat island' effect often amplifies temperatures further than in rural areas like Kent.
