# Weather fluctuations in UK and Ireland > Live situation record from CLSTR: https://clstr.news/situations/weather-fluctuations-in-uk-and-ireland > Updated: 2026-09-08T13:49:44.000Z. Sources: 30. Developments: 6. Weather patterns in the United Kingdom and Ireland have continued to oscillate between intense storms and unseasonably warm conditions. Following a period of thunderstorms and flash flooding in early August, and subsequent high pressure that raised wildfire concerns, the weather became increasingly unsettled by late August and early September. By early September, multiple low-pressure systems brought heavy rain and gusty winds, with gusts reaching 40-50 mph in parts of Scotland. Recent reports confirm that the summer of 2026 was the hottest on record for the UK, with an average mean temperature of 16.5°C between June and August. As of mid-September, the UK is preparing for a wet and windy period, with a band of rain expected to move southeast across Scotland, Northern Ireland, Wales, the Midlands, and East Anglia. While sunnier conditions are forecast to follow, experts warn that this rainfall may not be sufficient to end existing drought conditions in much of England and Wales. The Environment Agency indicates that sustained winter rainfall will be necessary to replenish groundwater levels. In Ireland, Met Éireann predicts similar changeable conditions, forecasting a blustery period with scattered showers and a wet Saturday, followed by a drier, sunnier Sunday. ## Claims - Summer 2026 was the hottest on record in the UK.
