UK Weather: Sunny spells ahead, but no heatwave
21 Sep
Summary
- Southern Britain will experience warmer and sunnier conditions early this week.
- Temperatures could reach 25C in London, but no official heatwave is forecast.
- Unsettled weather with rain and wind is expected from mid-week onwards.
Sunny spells and warmer temperatures are forecast for Britain at the start of the week, following a record-breaking summer and drought conditions. The warmest and brightest weather will predominantly affect southern England on Monday, with dry and sunny conditions expected. Further north and west, increased cloud cover and patchy rain are likely.
Tuesday promises some brighter intervals, though many areas will remain cloudy. Rain is predicted for northwest Scotland and Northern Ireland, while the southeast is expected to be sunny and warm. Temperatures could peak at 25C in London. An official heatwave requires specific temperature thresholds to be met for three consecutive days.
However, the pleasant weather is short-lived. The Met Office forecasts increasingly unsettled conditions from mid-week, with heavy rain anticipated on Wednesday. Thursday should offer a drier, brighter interlude before cloud and light rain return on Friday.
The unsettled theme is projected to continue through late September and into early October, with Atlantic weather systems bringing spells of rain, showers, and strong winds. Northern and western areas are most likely to experience the wettest and windiest conditions, though southern and eastern regions may see drier breaks.
