UK Weather

Tuesday 18th August Good morning. It’s Tuesday, 18 August 2026, and summer is looking rather mixed across the UK today. The warmest and driest weather will be across the south-east, where it should stay largely dry with highs around 25°C. There’ll be a fair amount of cloud at times, but it should still feel warm and quite humid, especially through the afternoon. Further west, the south-west looks fairly decent overall. A little light drizzle or patchy rain is possible earlier on, but there should be some brighter breaks later, with sunshine developing in places by mid to late afternoon. Temperatures here will reach the low to mid-20s. Wales and the Midlands start rather greyer, with some damp weather around during the morning — particularly across southern and western parts of Wales. It should become less wet as the day goes on, though skies may remain fairly cloudy. Highs will generally sit around 21 or 22°C. Northern England has a cooler, more unsettled feel. The north-west sees the wettest start, with rain around early in the morning and some fairly soggy roads for the first part of the commute. Further east and north-east, rainfall is lighter and patchier, but it will still feel breezy and rather fresh, with temperatures mostly around 18°C. Across Scotland, it’s a cool and blustery day for August, especially through central and eastern areas. Expect a lot of cloud, some light drizzle at times, and brisk winds making it feel cooler than the thermometer suggests. Northern Ireland follows a similar theme: mostly cloudy, a few spots of drizzle, and highs close to 18°C. So, the best of the warmth is in the south and south-east, while further north and west it’s cloudier, cooler, and at times damp. If you’re heading out early, an umbrella may be useful across Wales, the Midlands, and northern England — but for many, conditions should gradually settle into a quieter, if still rather cloudy, afternoon.
