Temperatures could hit 25°C across southern England and Wales this week as high pressure brings unseasonably warm conditions to mark the start of autumn, the Met Office has confirmed.
The settled weather will see much of the UK basking in largely dry and bright conditions from early September, with southern and central England experiencing the warmest temperatures. Northern England and the Midlands will see highs in the late teens to low 20s, whilst Scotland and Northern Ireland can expect mid to high teens - still pleasant for the time of year.
Coastal areas may feel cooler due to sea breezes, and clear overnight skies could bring patchy mist and fog to sheltered valleys during early mornings before clearing to sunshine. Light winds of 10-15mph will add to the settled conditions.
The Met Office stressed that whilst the temperatures are notably above seasonal averages, they won't challenge September records. The UK's highest September temperature remains 35.6°C, recorded in Bawtry, South Yorkshire, in 1906.
Forecasters advise the public to enjoy the fine weather responsibly, with sun protection recommended during midday hours and the importance of staying hydrated. No severe weather warnings are in place, though early morning travellers should check local forecasts for mist and fog updates.
The warm spell offers a welcome change from August's unsettled conditions, giving families and outdoor enthusiasts a final taste of summer before autumn's shorter days and cooler temperatures take hold.
