Travelers planning trips to Portugal, Spain, and France are advised to stay updated on the weather forecast as a significant early-summer heatwave is set to impact Western Europe. Meteorologists have cautioned that certain inland areas could potentially experience temperatures reaching 45°C in extreme scenarios.
The UK Met Office has verified the impending ‘European heatwave’ for a large part of Western Europe. Temperatures are set to soar starting today (Wednesday, June 17), with the peak heat expected between June 22 and June 26.
Meteorologist Aidan McGivern, in a detailed analysis by the Met Office, stated, “A heatwave across Europe is imminent, with temperatures likely to reach 40 degrees in Spain, France, and Italy, significantly above the average for mid-June.”
Coastal areas are expected to be cooler due to the moderating effect of the sea, unlike inland regions that are more susceptible to extreme heat. McGivern added, “Coastal regions will experience a considerable cooling effect from sea temperatures, whereas temperatures in inland areas are forecasted to reach the high 30s and even 41°C.”
The Met Office has also highlighted the broader heatwave signal. Aidan McGivern emphasized on the Met Office YouTube channel the unusual nature of these temperatures for this time of the year, stating, “It’s important to note that we’re in June. Temperatures are expected to be about 10 degrees higher than the average across Spain and France.”
Weather charts from the Met Office indicate temperatures reaching up to 40°C, with a caution that these models might underestimate the most extreme peaks in certain hotspots. McGivern mentioned, “We are anticipating temperatures in the 40s over the weekend, although it’s probable that the model is slightly underestimating by a couple of degrees due to its resolution.”
Reports from Portuguese news sources suggest the country could face an intense heatwave soon. Predictions indicate temperatures surpassing 40°C in many parts of Portugal and potentially hitting 45°C in some inland areas next week, as reported by Portugal Resident.
Concerns are raised as weather models increasingly indicate the formation of a potent ‘heat dome’ over Western Europe, hinting that Europe’s second heatwave of 2026 might be more severe and prolonged compared to the exceptional hot period between late May and early June.
