Britain sees unusually wet start to June 2026 before shift to warmer, sunnier weather

The United Kingdom experienced an unusually wet start to June 2026, with frequent rain, thunderstorms and temperatures several degrees below seasonal norms. Meteorologists attributed the unsettled spell to a persistent low‑pressure regime and an active jet stream that directed successive Atlantic systems across the country, reversing the dry and warm conditions that characterised much of the preceding spring.

Forecasts indicate the wet period will soon give way to clearer, warmer conditions. High pressure is expected to build northward from the south, bringing lighter winds and sunshine. Temperatures are projected to rise towards the upper 20s Celsius, with some areas in southern England and Wales potentially reaching 30 °C early next week. The contrast highlights a rapid transition from a damp, unsettled start to a comparatively hot and sunny spell.

The weather shift follows a recent record‑breaking heatwave at the end of May, which was driven by a hot continental air mass. The upcoming warmth is linked to strengthening high pressure rather than a similarly extreme continental plume.
