British tourists planning holidays in Spain, Greece, Turkey, and other popular European destinations have been warned about unusually hot conditions expected for summer 2026. A Super El Niño weather phenomenon is predicted to bring scorching temperatures to several parts of the world, including regions beloved by UK travellers.
Super El Niño Forecast
The World Meteorological Organisation (WMO) announced earlier in June that there is an 80% chance of the Super El Niño forming before September and a 90% likelihood of it persisting until November. UN Secretary General António Guterres has described the situation as urgent, warning that the phenomenon will exacerbate global warming and could lead to food shortages due to droughts and wildfires.
Impact on Travel
The extreme heat is already influencing travel trends, with some tourists considering cooler climates for their summer getaways. A recent survey by InsureandGo revealed that 70% of Britons believe their favourite holiday destinations will become too hot to visit within the next five years. Seasonal temperatures across Europe are expected to be above average, making southern countries particularly sweltering.
National Responses
Spain
In Spain, new regulations require outdoor hospitality services to reduce operations when the State Meteorological Agency (AEMET) issues orange or red alerts. This means restaurant and bar terraces may close during peak heat to protect staff health and safety.
Greece
Greek media reports anticipate a hotter-than-usual summer, with temperatures potentially soaring well beyond typical July and August levels.
Turkey
Turkey is also expected to experience extreme heat, though specific measures have not yet been detailed.
Safety Advice
Charities and official organisations advise staying in cool, air-conditioned spaces during the hottest parts of the day, typically from late morning to late afternoon. Age in Spain, an organisation for older people, recommends light meals, ample fluid intake, and avoiding physical activity during peak heat.
The last Super El Niño occurred 11 years ago, during 2015-2016, and resulted in hotter-than-normal summers. With this year's event, authorities urge tourists to remain vigilant and prioritise safety.
