Spain prepares for a hotter than usual summer with storms and extreme heat

A lot of people across Spain have already started saying the same thing lately : ‘We’re still in May… so how is it already this hot?’

After weeks of unusually high temperatures, packed terraces and heavy afternoons that already feel closer to July than spring, forecasters now believe summer 2026 could become even tougher than many people expected.

According to the latest outlook discussed by Meteored climatologist Samuel Biener, Spain is likely heading towards a warmer than normal summer across much of the country, with temperatures in some areas potentially ending up between 1.5 and 3 degrees above seasonal averages.

And while the heat itself is already making people nervous, meteorologists are also watching another problem developing quietly in the background : Storms.

Not the kind of long rainy periods people sometimes hope for during hot weather either.

Instead, forecasters believe parts of Spain could see a more unstable summer with sudden storms, hail and violent downpours becoming more frequent in some regions.

Honestly, after the strange weather swings Spain has already experienced this spring, the forecast does not feel particularly shocking anymore. Because for many people, it already feels like summer arrived far too early.

Why forecasters think this summer may feel especially exhausting

The latest seasonal models used by Meteored continue pointing towards persistent warmth across large parts of the country during the coming months.

Central Spain appears especially exposed. Areas including Madrid, Castilla La Mancha, Castilla y León and Extremadura could see some of the strongest temperature anomalies compared with what would normally be expected during summer.

And people living in those areas already know what that can mean in practice :

• Very hot nights.
• Heavy air sitting inside apartments long after sunset.
• Cities that barely cool down properly even at midnight.

That is often the moment when summer starts becoming physically draining rather than simply pleasant.

Especially during long heat episodes. Meteorologists are still being careful not to officially predict specific heatwaves this far in advance because seasonal forecasting always contains uncertainty. But Samuel Biener openly admits that recent years clearly show an increasing tendency towards periods of extreme heat in Spain.

And honestly, most residents no longer need scientific charts to notice the difference.

People feel it already, air conditioning starts earlier, fans come out sooner and afternoons become harder to tolerate much faster than they used to.

In some southern cities, people are already adjusting routines before June has even started, avoiding the streets during the hottest hours because temperatures suddenly feel far more aggressive than expected for this time of year.

Storms could become one of the biggest problems this summer too

What makes this forecast more complicated is that meteorologists are not only talking about heat. Several regions could also experience more storm activity than usual during the coming months.

According to Meteored’s current projections, the Pyrenees, Mediterranean side of Spain, southern Iberian mountain areas and even the Canary Islands may end up seeing more unstable conditions over the summer period.

Of course, forecasting storms months ahead is difficult.

Rainfall is one of the hardest things for meteorologists to predict accurately over long periods because storm systems depend on many rapidly changing atmospheric factors.

Still, forecasters say the current signal for instability is becoming increasingly noticeable in some areas.

And honestly, many people across Spain already feel like summer storms have changed over recent years.

They often arrive faster, more violently and sometimes with almost tropical intensity.

A normal sunny afternoon can suddenly turn into hail, violent wind and flooded streets within less than an hour.

That pattern has already appeared several times this spring. Especially after days of trapped heat build up.

The heat keeps building quietly in the background until the atmosphere suddenly snaps.

Lightning starts flashing across the sky, huge drops of rain begin hammering the ground and violent gusts arrive almost without warning.

Then come the short but intense storms that can turn streets chaotic within minutes before disappearing again almost as quickly as they arrived.

Meteorologists believe similar situations could repeat this summer if current conditions continue developing the way models currently suggest.

Many people in Spain are already dreading another difficult summer

For tourists, headlines about hot weather in Spain often sound attractive. For many residents, the reality feels more complicated now. Because extremely hot summers no longer simply mean beach weather.

They increasingly affect daily life in exhausting ways. Electricity bills rise sharply because air conditioning runs almost constantly. Sleeping becomes difficult during tropical nights.

Older buildings trap heat for days. Outdoor workers struggle during afternoon hours and drought concerns quickly return every time rain disappears for long periods.

That growing discomfort is one reason seasonal forecasts now attract far more attention than they used to. People genuinely want to know what kind of summer may be coming. Especially after several years where heat records across Spain have repeatedly fallen earlier and earlier.

Experts say Spain’s summer temperatures cannot simply be explained by El Niño alone

According to Meteored, European weather patterns depend heavily on other atmospheric factors too, including the behaviour of the polar jet stream.

Still, whatever the technical explanation behind it, the feeling many people have across Spain is becoming increasingly similar every year.

A lot of people across Spain now have the same feeling every year.

Summer seems to start earlier than expected, the heat hangs around for much longer and storms often feel far more aggressive than they used to. Even the nights no longer cool down properly in many parts of the country.

For now, forecasters are still stressing that long range models can evolve over the coming weeks. But after the temperatures Spain has already experienced before June has even started, many residents are already looking ahead towards July and August with a certain amount of concern.

Because if late May already feels like this, people are starting to wonder what the middle of summer might look like.
