Red heat-health alert
The UK Health Security Agency (UKHSA) has issued two heat-health alerts for London. An amber alert is in place until 8pm today (Tuesday 23 June 2026).
A red heat-health alert – the highest level, will be in place from 9am on Wednesday 24 June to 9pm on Thursday 25 June 2026.
A red alert is rare and signals population‑wide health risks, not just for those who are usually more vulnerable to extreme heat. It can lead to serious illness or danger to life.
As temperatures rise, please take extra care, especially for those who may feel the heat more than others.
Tips to stay safe in the heat
- Look out for older adults, people with health conditions and those living alone
- Keep indoor spaces cool by closing curtains on sun‑facing windows
- Stay hydrated – drink plenty of water and carry a bottle when out
- Never leave anyone in a parked vehicle, including pets
- Avoid the sun between 11am and 3pm when UV rays are strongest
- Use high‑SPF sunscreen and wear a wide‑brimmed hat
- Avoid strenuous activity during the hottest part of the day
Swimming safety and open water
- Swimming is not permitted in any lakes in Redbridge
- Open water can be extremely dangerous due to hidden currents, cold temperatures and underwater hazards
- The London Fire Brigade has produced a video on open‑water dangers — please take a moment to watch and share it
Keep updated on service changes
- To keep crews safe in the extreme heat, waste collections will start earlier than usual
- Please place your bins at your boundary by 5am on your collection day this week
Schools
- Parents and carers are advised to check directly with individual schools to see if there are any changes to school opening times
