Spanish authorities have issued a safety warning for holidaymakers as the country braces for another heatwave, with temperatures potentially reaching 44°C in some regions. The warning, announced on Tuesday, urges precautionary measures to protect wellbeing.
Risk of Dehydration
Spain's Minister of the Interior posted on X, formerly Twitter, stating that the "risk of dehydration in summer is real." The post advised: "On long trips, the heat takes its toll. Make frequent stops. Drink water. Equip yourself with specialized, breathable, or cooling clothing. Protect yourself from the sun and travel safely."
FCDO Guidance
The UK's Foreign, Commonwealth and Development Office (FCDO) advises travellers to check warnings from the Spanish Meteorological Office (AEMET) and European Meteorological Services. Holidaymakers are also told to "check with your travel provider and follow advice from local authorities."
Previous Heatwave Impact
Spain is still recovering from a heatwave last month that caused 1,028 excess fatalities—more than double the heat-related deaths from the previous year. The first six months of 2026 were the warmest on record in Spain, with temperatures averaging 1.6°C above normal, according to AEMET.
The Four-Hour Rule
The FCDO signposts NHS advice for staying safe in hot weather, which includes a four-hour rule. Holidaymakers are advised to reduce heat exposure and remain indoors where possible, especially between 11am and 3pm, the hottest part of the day. Other recommendations include finding shade, wearing a hat and light clothing, using sunscreen, staying hydrated with cold drinks and chilled food, and avoiding dehydrating beverages like alcohol and caffeine.
To keep homes cool, people should shut windows, blinds, and curtains during the day to prevent heat from entering, then open them at night to let cooler air in. Electric fans should only be used if the indoor temperature is below 35°C. It is also important to check indoor room temperatures regularly and look in on vulnerable family members, friends, or neighbours.
