Certain groups remain at increased risk and need to take extra care to protect themselves from the health impacts of hot weather. According to NHS guidance, the groups most vulnerable to serious heat-related illness include:
- Older people, especially those aged 65 and over.
- People with health conditions such as heart or lung disease, diabetes, kidney disease, Parkinson’s disease, dementia and serious mental health conditions.
- Pregnant women, babies and young children (up to 5 years).
- People taking multiple medications that increase heat sensitivity.
- Individuals who may struggle to keep cool, including those who spend a lot of time outdoors (for hobbies or work), who live alone and may be unable to care for themselves, people experiencing homelessness or who experience alcohol or drug dependence.
- People who are already ill and dehydrated (for example from diarrhoea and vomiting).
Public Health advice for all residents
To reduce the risk of heat exhaustion, heatstroke and worsening of existing health conditions, residents are advised to follow this guidance from the NHS:
- Stay out of the heat where possible. If outdoors, keep to shaded areas, carry water, avoid activity between 11am and 3pm, and wear light clothing, sunscreen (at least SPF50 for children) and a hat. Babies under 6 months should be kept out of direct sunlight all day.
- Keep cool indoors by closing windows and curtains during the day and opening them at night when temperatures drop. Fans can help if indoor temperatures are below 35°C
- Keep hydrated with plenty of water; avoid alcohol, caffeine and very hot drinks.
- Cool yourself with cold showers, damp cloths, or cool drinks and foods.
- Monitor indoor temperatures, especially in bedrooms. If you have young children, make sure there is adequate air flow where they sleep, remove any clothing they don’t need and check on them regularly to make sure they don’t overheat.
- Stay safe in small, closed spaces and make sure that babies, children, older people and pets are not left alone in stationary cars which can get dangerously hot, very quickly.
- Watch for symptoms of heat exhaustion and heatstroke, including headache, dizziness, nausea, confusion, cramps or high temperature. Seek emergency help if symptoms worsen.
- Check in on neighbours, friends and relatives who may be at higher risk of health impacts due to hot weather. Make sure they have access to water, shade, and ways to cool down.

Additional precautions during hot weather
Hot weather can have wider impacts beyond health, so residents are encouraged to plan ahead and take extra care.
- Travel disruption – high temperatures can affect road and rail travel. Check your journey before setting off, allow extra time, and carry water with you.
- Air quality – air pollution levels can rise during periods of hot weather. People with respiratory conditions may wish to limit strenuous activity outdoors, particularly during the hottest parts of the day, and carry their rescue inhalers with them. More information is available online.
- Fire risk – dry conditions increase the risk of fires. Take care with BBQs, open flames and disposable barbecues, and avoid lighting fires in open spaces.
- Water safety – rivers, lakes and the sea can seem tempting in the heat, but open water can be dangerous, even for strong swimmers. If you do head for the water, choose lifeguarded areas if possible, avoid alcohol and don’t swim alone, and take it slow when entering cold water to avoid shock. If you get into difficulty, follow RNLI guidance and ‘Float to Live’. Remember that babies and young children are also at risk in gardens and nearby outdoor spaces, including in paddling pools – follow these tips to ensure children enjoy water safely at home.
- Pets and animals – protect pets and animals by providing constant access to fresh water and shade. Visit the RSPCA website for further guidance.
In Hampshire, the County Council is taking a number of steps to help keep residents and staff safe during the hot weather.
- Local roads - the County Council's highways teams are monitoring roads during this period of high temperatures. During prolonged hot weather, road surface temperatures can become extremely high - often reaching the high 50s to low 60s (°C) - causing tarmac to soften and potentially melt, which may lead to uneven surfaces. The gritter fleet is ready to spread stone on the most affected roads, helping to protect the surface and improve grip. Drivers are encouraged to take care when planning a journey - more guidance is available online.
- Hampshire Waste Recycling Centres - on Wednesday 24 June and Thursday 25 June, all Hampshire County Council Household Waste Recycling Centres (HWRCs) will operate reduced hours, closing at 12.30pm on both days. This is to support the health and wellbeing of both customers and staff due to the extreme heat forecast. People with existing appointments will be contacted directly to advise of this change. HWRCs are expected to operate as normal from Friday 26 June.
- Schools – the County Council has contacted schools advising them to act in accordance with guidance from the Department for Education and from the local authority’s Health and Safety and Public Health teams. While schools are not normally expected to close during heatwaves, they are responsible for taking their own decisions and have individual risk assessments in relation to hot weather. Some schools, as well as post-16 and early years settings, are opting to close or operate shorter days and will be in touch with parents and carers directly. Visit our website for a full list of local school closures.
