Southern England is bracing for a severe heatwave, with amber health alerts issued across London, the South-East, East of England, and South West regions. Temperatures are expected to climb steadily from Friday, potentially reaching up to 38C (104F) in some areas by Monday, according to multiple reports.

The UK Health Security Agency (UKHSA) has issued amber alerts warning of a risk to the wider population, not just vulnerable people. Yellow alerts are also in place for the Midlands and other regions. The Met Office said that some areas in southern England are likely to meet heatwave criteria by Saturday, with temperatures potentially exceeding the UK's June maximum temperature record of 35.6C set in London in 1957 and Southampton in 1976.

The heatwave is expected to bring very humid and muggy conditions, with a chance of thunderstorms later this week. Officials have expressed concerns about water-related incidents such as cold-water shock and drowning after at least 17 people died when they got into trouble in open water during the record-breaking May heatwave three weeks ago.

The Met Office has warned of an increase in potential water safety incidents as more people are expected to visit coastal areas, lakes or rivers. The agency has reiterated its water safety advice, reminding people that the sea is still cold at this time of year. Overnight temperatures are also expected to be very high, with widespread tropical nights where the temperature does not drop below 20C across southern England.
