Temperatures across Hampshire are expected to reach and exceed 35°C this week, with a Red Heat-Health Alert from the UK Health Security Agency in place from Wednesday to Thursday.
This is the highest level of alert and means the heat could have serious impacts on everyone’s health – not just those who are usually considered more vulnerable.
Please take care and follow some simple steps to stay safe:
🌡️ Avoid the sun between 11am and 3pm where possible and stay in the shade.
🚰 Drink plenty of water and take it easy during the hottest part of the day.
👕 Wear light, loose clothing, a hat and sunscreen outdoors.
🏠 Keep your home cool by closing curtains or blinds in sunny rooms.
🤝 Check in on neighbours, friends and family – especially older people, young children and anyone with health conditions.
🚗 Never leave children or pets in a parked car, even for a short time.
Thinking of cooling off in the water? Rivers, lakes and the sea can be dangerous, even for strong swimmers. Choose lifeguarded areas where possible, avoid alcohol and never swim alone.
Know the signs of heat illness:
⚠️ Heat exhaustion can cause dizziness, nausea and extreme thirst.
🚑 Heatstroke is an emergency. If someone becomes confused, stops sweating or has trouble breathing, call 999 immediately.
Hot weather may also affect travel, air quality and increase fire risk, so plan ahead and take extra care.
