A UK heatwave could push May temperatures to new highs, with amber heat-health alerts in place and parts of the country already seeing 30C readings. Here’s what to know about where the heat’s strongest, how it could set records, and what it means for travel, health, and daily life.
Forecasts suggest a real possibility of a new May high temperature, with regional variations. Kent and southern parts have already hit 30C, and Met Office guidance indicates the potential for a national May record depending on how the heat builds as the week progresses.
Early readings show the southeast and eastern England experiencing the warmest conditions, with forecasts pointing to a peak near London–themed zones. However, many parts of southern England could see consistently high temperatures, while northern regions may trend cooler. Check local forecasts for your area.
Amber heat-health alerts are active across affected regions. Advice includes staying hydrated, keeping out of direct sun during peak hours, checking vulnerable people (elderly, young children, those with chronic conditions), and cooling strategies like fans or air conditioning where available.
Expect busier road networks, rail disruption from heat-related delays, and crowded popular destinations. Heat can also limit outdoor activities and travel schedules. If planning trips, monitor transport updates, book indoor activities during peak heat, and allow extra travel time.
Authorities are adapting with heat-health planning, cooling centres, and temperature monitoring. Longer-term efforts include improving urban cooling, weather-resilient transport schedules, and public-facing alerts to keep the public informed and safe during heat events.
Plan around cooler parts of the day for outdoor activities, stay hydrated, use sun protection, and check local advisories. If you have health concerns or work outdoors, follow official guidance and consider adjustments to routines to avoid peak heat.
The Met Office predicts there will be highs of 23C in Manchester, 26C in London and 20C in Cardiff by the end of the week
