when will it get warmer uk

In the UK, it usually starts to feel noticeably warmer from around late March into April, with the most reliably warm weather arriving in late May through August in most years. Longer‑term climate outlooks also suggest that the mid‑2020s, including 2026, are likely to be among the warmest years on record globally, which tends to nudge UK averages upward too.

Typical UK warm‑up timeline

• Late March–April: Days get longer, frost becomes less common, and “light‑jacket” weather appears more regularly, with average temperatures in England around 9–12°C in April–May.

• May–June: This is when it usually “feels” like it has finally got warmer, with more dry, mild days and averages moving into the mid‑teens Celsius.

• July–August: These are typically the warmest months, with many areas seeing mid‑teens to low‑20s Celsius, and occasional heatwaves pushing temperatures much higher.
