18 June 2025

Temperatures are set to reach highs of 25 degrees across the Isle of Wight over the next few days as the population is also set to increase with the Isle of Wight Festival taking place from 19 to 22 June. 

Whilst many people enjoy the warmer days, an increased period of hot weather can cause some to become unwell through dehydration, sun burn, heat exhaustion and heatstroke. 

Steve Parker, Medical Director for Isle of Wight NHS Trust said:  “We are forecasting a period of hot weather over the next few days and are encouraging people to stay safe by taking precautions to keep well.  

“If possible, we advise people to keep out of the sun at the hottest time of the day, between 11am and 3pm. If you are heading to the festival this weekend, make sure you drink plenty of water, wear plenty of sunscreen and dare I say moderate your intake of alcohol.” 

“The warmer weather can also increase the risk of heart attack, stroke, lung problems and other diseases. Older people, babies and young children are also more likely to be unwell from hot weather. People with certain underlying medical conditions can also be vulnerable to the effects of hot weather. We encourage people to take the necessary steps and look after themselves and each other. This will also help avoid increasing pressure on local NHS services, particularly as we are set to welcome visitors to our island for the festival weekend.”

Follow the festival hot weather advice 

You can take some simple steps to stay well at a festival during periods of hot weather, remember to carry a refillable water bottle with you and drink it throughout the day, wear sun cream and a sunhat and avoid excess alcohol. Keep a look-out for signs of heat-related harm in yourself, your friends, and other people around the festival. The signs include:  

  • a headache  
  • dizziness and confusion  
  • loss of appetite and feeling sick  
  • excessive sweating and pale, clammy skin  
  • cramps in the arms, legs and stomach  
  • fast breathing or pulse  
  • a high temperature of 38C or above  
  • being very thirsty  

If you experience any of these symptoms, drink some water or diluted fruit juice to rehydrate, find somewhere shaded to sit down and rest and avoid excess alcohol. If symptoms have not gone away after 30 minutes of resting, seek help from one of the medical centres at the festival.
