UK Weather Heatwave Likely as Temperatures Set to Reach 30°C in Coming Days A new heatwave is expected to be declared in the United Kingdom within the coming days, as forecasters warn that temperatures could climb to around 30°C in parts of the country. The warm spell is forecast to build through the week, driven by a high pressure system that is expected to bring increasingly dry and sunny conditions, particularly across southern and eastern England.

Meteorologists say temperatures that are currently in the low-to-mid 20s could rise into the high 20s and potentially reach 30°C or slightly above in some areas by the weekend. Southern regions, including London and surrounding counties, are expected to experience the highest temperatures, while northern parts of the UK will likely remain cooler but still warm for the time of year. Weather experts say several areas may meet official heatwave criteria if high temperatures persist for multiple days. In the UK, a heatwave is declared when temperature thresholds specific to each region are reached for at least three consecutive days. The UK Health Security Agency UKHSA is expected to monitor conditions closely, as heatwaves can increase risks for vulnerable groups, including the elderly and those with existing health conditions.

During similar recent warm spells, health authorities have advised the public to

  • Stay hydrated
  • Avoid prolonged exposure to the sun during peak hours
  • Check on vulnerable neighbours and relatives

Forecasters attribute the rising temperatures to a developing high pressure system, which can trap warm air over the country and reduce cloud cover, allowing more intense sunshine. This pattern is often associated with settled summer conditions and can lead to short but intense heatwaves. While temperatures are expected to peak in the coming days, forecasters say there is still some uncertainty about how long the hot conditions will last, as changes in pressure systems could bring cooler or more unsettled weather later in the month. For now, the UK is on track for its first widely felt heatwave conditions of the period, with widespread warmth and potential peak temperatures around 30°C in parts of the country.
