A powerful surge of scorching air from North Africa is set to engulf large parts of Spain and France, triggering what meteorologists are calling one of the most intense heatwaves of the year so far.

The extreme heat event is expected to begin this weekend and intensify through early next week, with some regions potentially experiencing temperatures between 40°C and 45°C, well above seasonal averages.

Forecasters warn that the combination of extreme daytime heat, unusually warm nights, and the possibility of severe thunderstorms could create dangerous conditions across southwestern Europe.

Massive African Heat Dome Expands Across Europe

Meteorologists say the heatwave is being driven by a strong ridge of hot, dry air moving northward from Africa.

This atmospheric pattern is allowing extremely warm air to spread across the Iberian Peninsula before extending into France and other parts of western Europe.

Climate monitoring agencies indicate that temperatures will rise rapidly from Saturday onward, with the most severe conditions expected between Sunday and Tuesday.

Spain Among the Hardest-Hit Countries

Spain is expected to experience some of the highest temperatures during the event.

Forecast models suggest that many regions could surpass 40°C, particularly in the major river basins of the Ebro, Tagus, Guadiana, and Guadalquivir.

Even areas that are normally cooler at this time of year, including parts of Galicia and the Cantabrian coast, could approach or exceed 38°C.

Meteorologists warn that these values are exceptionally high for mid-June and more typical of the peak of summer.

France Also Facing Extreme Heat

France is also expected to be heavily impacted by the incoming heatwave.

Temperatures are forecast to rise significantly across southern and central regions, with some locations potentially approaching 40°C or higher.

Authorities are closely monitoring the situation as the country continues to face increasing heat-related risks, including health concerns, water shortages, and elevated wildfire danger.

Nights May Offer Little Relief

One of the most concerning aspects of this heatwave is the forecast for exceptionally warm nighttime temperatures.

Meteorologists warn that overnight lows may remain above 25°C across many areas, creating what is known as “tropical nights.”

These conditions can significantly increase health risks because the human body has limited opportunity to cool down between periods of intense daytime heat.

Peak Heat Expected Early Next Week

Weather experts say Monday and Tuesday are likely to be the hottest days of the event.

Forecasts indicate that some regions could see temperatures approaching 45°C, particularly in southern Spain and inland areas where hot air becomes trapped under high-pressure conditions.

The thermal anomaly—the difference between forecast temperatures and normal seasonal values—could reach an extraordinary 10°C to 15°C above average in some northern regions.

Such departures from normal conditions highlight the exceptional nature of this weather event.

Severe Storms Also Possible

Despite the dominance of extreme heat, meteorologists are also warning about the possibility of powerful thunderstorms developing in some areas.

The interaction between intense heat and atmospheric instability could trigger severe storms capable of producing heavy rainfall, strong winds, and localized flooding.

Experts stress that heatwaves and severe thunderstorms often occur together during periods of extreme summer weather.

Heatwave May Ease But Hot Weather Will Continue

Current forecasts suggest that the most intense phase of the heatwave will begin to weaken after June 23.

However, meteorologists warn that temperatures are likely to remain above seasonal averages throughout much of the following week.

While conditions may become slightly less extreme, persistent warmth is expected to continue across much of southwestern Europe.

Europe Faces Another Summer of Extreme Weather

The upcoming heatwave is the latest example of increasingly intense temperature extremes affecting Europe in recent years.

Scientists have repeatedly warned that climate change is increasing the frequency, duration, and intensity of heatwaves across the continent.

With summer only just beginning, authorities are urging residents to stay hydrated, avoid unnecessary outdoor activities during peak heat hours, and closely follow official weather updates as this major heat event unfolds.
