The Met Office's latest three-month outlook, published on June 1, 2026, forecasts that temperatures are likely to be above average throughout June, July, and August. Prepare for an increased chance of heatwaves and heat-related impacts across the UK this summer.

This follows a late spring heatwave that saw temperatures reach a record 35.1°C at Kew Gardens in London on May 26, 2026. This was the highest temperature ever recorded in May in the UK, surpassing the previous record from 1944. Spring 2026 was also the warmest on record for England and Wales, and the third warmest for the UK overall.

What is happening right now

The Met Office has confirmed its summer 2026 outlook points to a higher probability of prolonged periods of hot weather. While specific dates for future heatwaves are not yet issued, the overall trend indicates a warmer-than-average season.

Who is affected

Everyone in the UK could be affected by higher temperatures, but particular vigilance is needed for vulnerable groups. This includes older people, young children, and individuals with pre-existing health conditions, who are at higher risk of heat-related illness.

What to do immediately

Take these steps to prepare for and manage hot weather:

Stay Hydrated: Drink plenty of fluids, even if you don't feel thirsty. Water is best.
Seek Shade: Avoid direct sun exposure, especially between 11am and 3pm when UV radiation is strongest.
Keep Cool: Wear light, loose-fitting clothing. Take cool showers or baths.
Check on Others: Look out for vulnerable friends, family, and neighbours who may struggle in the heat.
Protect Your Home: Close curtains and blinds in rooms that face the sun to keep indoor spaces cooler.

What this means for you

You should adjust your daily routines to account for potentially higher temperatures throughout the summer. This includes planning outdoor activities for cooler parts of the day and ensuring your home environment remains as cool as possible. Be prepared for potential travel disruptions if infrastructure is affected by extreme heat.

What to watch for

While the Met Office outlook points to a warmer summer, weather patterns can still be variable. Keep an eye on local forecasts and any specific heat health alerts issued by the UK Health Security Agency (UKHSA) or the Met Office for more immediate, localised warnings.
