As summer temperatures rise, it's important to stay informed and prepared.
While many of us enjoy the sunshine, hot weather can pose serious health risks, especially for vulnerable groups such as older adults, young children, and those with pre-existing health conditions. With climate change making heatwaves more frequent and intense, knowing how to stay cool and safe is more important than ever.
UK temperature records: A changing climate
The UK has experienced increasingly extreme temperatures in recent years. On 19 July 2022, the UK recorded its highest ever temperature: 40.3°C in Coningsby, Lincolnshire. This surpassed the previous record of 38.7°C set in 2019. Wales and Scotland also saw new records, with 37.1°C in Hawarden and 34.8°C in Charterhall respectively. Northern Ireland reached 31.3°C in Castlederg in July 2021.
These records reflect a broader trend of rising temperatures and more frequent heatwaves. Blocking anticyclones, high-pressure systems that linger over the UK, can lead to prolonged periods of hot, dry weather, increasing the risk of heat-related health issues and infrastructure strain.

How to stay cool and safe
The UK Health Security Agency recommend several practical steps to stay safe during hot weather:
- Keep your home cool: Close blinds or curtains during the day and ventilate at night to allow cooler air in.
- Stay hydrated: Drink plenty of fluids and avoid alcohol, which can dehydrate you.
- Dress appropriately: Wear lightweight, light-coloured clothing and a wide-brimmed hat.
- Avoid peak heat: Stay out of the sun between 11am and 3pm when UV rays are strongest.
- Use sunscreen: Apply high-factor sun cream regularly, even on cloudy days.
- Limit physical activity: Avoid strenuous exercise during the hottest parts of the day.
- Check on others: Look out for neighbours, friends, or relatives who may be at risk.
If you feel unwell with a high temperature, fatigue, or dizziness, it could be a sign of heat exhaustion or heatstroke. Seek shade, hydrate, and cool down immediately. For more information, visit the NHS heat illness guidance.

Pet safety in the heat
Our pets are just as vulnerable to heat as we are. The British Veterinary Association offers the following advice:
- Hydration and shade: Ensure pets always have access to fresh water and a cool, shaded area.
- Avoid hot walks: Walk dogs early in the morning or late in the evening. Use the five-second tarmac test—if it’s too hot for your hand, it’s too hot for their paws.
- Cooling techniques: Freeze water bottles for rabbits or mist their ears with cool water. Cover outdoor enclosures with damp towels to provide shade.
- Sun protection: Some pets, especially those with light or fine fur, may benefit from pet-safe sun cream on sensitive areas like ear tips.
- Wildlife care: Leave out shallow bowls of water for birds and hedgehogs.
Watch for signs of heatstroke in pets, such as heavy panting, restlessness, or lack of coordination. If you’re concerned, contact a vet immediately.
As our summers grow hotter, preparation and awareness are key. By taking simple precautions, we can all enjoy the sunshine safely, while protecting ourselves, our loved ones, and our pets. If you’re concerned about the temperature in your home, your local authority’s environmental health office can help assess for heat-related hazards.
