Spain is currently experiencing an exceptional weather situation that is causing growing concern among meteorologists. While an unusually early heatwave is initially spreading across large parts of the country, a drastic change in weather is already expected by the weekend. After temperatures of up to 39°C, a so-called DANA is set to move across Spain, bringing severe thunderstorms, hail, and localised flooding.

Spain is experiencing an early heatwave in the middle of May
Since the beginning of the week, temperatures have been rising significantly across many parts of the country. According to the Spanish meteorological agency AEMET, large areas of Andalusia, Extremadura and Castilla-La Mancha are particularly affected. In cities such as Seville, Córdoba and Granada, temperatures are expected that are normally more typical of July or August. In some places, temperatures may climb to as high as 39°C. The Ebro Valley and regions in the north-east of Spain are also clearly feeling the effects of this unusual heat.
Meteorologists are already describing this as one of the earliest intense heat spells in recent years. Temperatures are locally up to ten degrees above the long-term average for May. This is being driven by a hot air mass from North Africa, which is currently moving over the Iberian Peninsula and effectively bringing an early taste of midsummer conditions to Spain.
Tropical nights are adding to the strain
Not only is the daytime heat causing difficulties for many people, but nights are also offering little relief. In many areas, temperatures are barely dropping. In some regions, so-called tropical nights are expected, where temperatures do not fall below 20°C even overnight. Elderly people, children, and those with existing health conditions are particularly affected by this sustained heat stress.
Health authorities therefore recommend avoiding physical exertion during the hottest midday hours, drinking plenty of water, and staying out of direct sunlight. At the same time, the ongoing dry conditions are significantly increasing the risk of wildfires in several regions of the country.
A dangerous DANA is expected over the weekend
However, while Spain is initially suffering under extreme heat, the next weather threat is already on the horizon. From Saturday, a so-called DANA is expected to move in from the west across Spain. The term stands for “Depresión Aislada en Niveles Altos” and refers to an isolated cold-core low in the upper atmosphere.
This weather pattern is feared in Spain because it often triggers severe storms. When hot air near the surface collides with cold air in the upper atmosphere, highly energetic thunderstorm cells can form. Meteorologists therefore warn of an explosive combination of heat and unstable air conditions.
According to current forecasts, central Spain, the northern regions, and various mountainous areas are most likely to be affected. The situation is also being closely monitored along parts of the Mediterranean coast.
Severe thunderstorms, hail, and flash floods are possible
With the arrival of the DANA, experts expect severe thunderstorms, heavy rainfall, and strong wind gusts in some areas. Hailstorms with larger hailstones cannot be ruled out either. Localised flash flooding could be particularly problematic. After a prolonged dry spell, the parched ground is often unable to absorb large amounts of rain quickly enough, which can lead to streets, underpasses, and smaller rivers being flooded within a very short space of time.
Meteorologists also warn that weather conditions could change dramatically within just a few hours. Regions still suffering from extreme heat during the day could be hit by severe thunderstorms shortly afterwards.
AEMET is monitoring the situation with concern
The Spanish meteorological agency AEMET is currently monitoring the development very closely. It is still difficult to predict which regions will ultimately be most affected, as DANAs are considered particularly unpredictable. However, it already appears clear that Spain is heading towards a weekend marked by extreme weather contrasts.
Extreme weather events continue to increase
Many meteorologists increasingly see such weather patterns as a sign of climate change. Heatwaves in Spain are occurring earlier in the year, while severe storm events are also becoming more frequent. In recent years, numerous temperature records have already been recorded.
Experts warn that extreme swings between heatwaves and severe storms could become more frequent in the future. Spain is now among the European countries most strongly affected by rising temperatures and increasingly extreme weather conditions.
Tourists and residents are advised to take precautions
Anyone currently in Spain or planning to travel there in the coming days is advised to closely follow the latest weather warnings. Authorities recommend avoiding prolonged exposure to direct sunlight and exercising particular caution during forecast thunderstorms. In heavy rain, dry riverbeds, underpasses, and flood-prone roads should be avoided.
Official weather warnings could be issued at short notice in several provinces as the situation becomes clearer.
