Second half of summer to bring chances for rain but heatwave threat persists
The UK's weather in the second half of summer could become more variable, with rain potentially returning to some areas following an extended dry period, particularly affecting Scotland and Northern Ireland. However, weather forecasters emphasise considerable uncertainty in their predictions at this time range, with computer models providing conflicting guidance about whether persistent high pressure will continue or allow Atlantic weather systems to dominate.
Temperatures are forecast to remain above seasonal averages through late July and August, with additional heat waves remaining a realistic possibility. This would continue an already record-breaking summer that has seen multiple historical temperature benchmarks surpassed, including the highest June temperature on record and the most days exceeding 35C in a calendar year, reflecting the exceptional nature of weather patterns in 2026.
- Second half of summer may see more rain and variable conditions, but temperatures expected to remain above average with further heatwaves possible
- Summer 2026 has already broken multiple temperature records, including highest June temperature and most days above 35C in a single year
