The United Kingdom is bracing for its fourth heatwave of the year, with amber and yellow health alerts taking effect this Wednesday. Meteorologists expect the mercury to hit a peak of 35C in the warmest regions.
Originating from North Africa, a mass of hot air is moving north through France and Iberia before reaching the UK. Southern and eastern England, along with parts of the Midlands, will face the most intense heat. While most of the country will see this heatwave pass by Thursday, temperatures are predicted to stay well above the seasonal average, remaining in the mid-to-high 20s through the weekend.
The UK Health Security Agency has placed the East Midlands, East of England, London, and the south-east under amber alerts from 09:00 BST on 29 July until 09:00 BST on 30 July. These alerts signal potential pressure on health and social care systems, with elevated risks for individuals aged 65 and over and those with pre-existing conditions. Less severe yellow alerts have been designated for the south-west, West Midlands, and Yorkshire and the Humber.
Persistent dry conditions are worsening as this heat spike arrives. The Met Office reports that England has seen only 4.4mm of rainfall this month, marking one of the lowest levels on record. Dry soil and vegetation have already prompted hosepipe bans for millions and fueled wildfire concerns. Despite a weather front expected to lower temperatures by up to 8C on Thursday, the lack of significant rainfall remains a primary worry for the coming weekend.
