Spain has just broken a summer heat record and we’re only halfway through July

If you’ve spent the past few weeks sleeping with the windows open, checking the weather before leaving the house or planning your day around the hottest hours, you’re far from alone. Spain has officially recorded its hottest first half of summer since records began in 1961, according to the State Meteorological Agency (AEMET). Between 1 June and 15 July, the average temperature across mainland Spain reached 24.5C, the highest ever measured for this period of the year.

It’s a milestone that reflects what many people have already been experiencing rather than introducing something new. Across much of the country, the heat has lingered day after day, with two major heatwaves arriving before the middle of July. Even places that usually enjoy milder summers have struggled with unusually high temperatures, while nights have brought little relief.

With several weeks of summer still ahead, the latest figures raise an obvious question. Is this simply an exceptional year, or are these becoming the kind of summers Spain will have to get used to?

A summer that has felt different from the very beginning

For many people, this summer didn’t suddenly become hot. It started that way.

From the first days of June, temperatures remained consistently above what would normally be expected, and according to AEMET, almost every day between 1 June and 15 July recorded values higher than the average for the 1991 to 2020 reference period.

Overall, the average temperature during those six weeks was 3.3 degrees above normal, enough to rewrite Spain’s weather records.

Unlike previous years, there was very little chance for the country to cool down between hot spells.

The first heatwave arrived at the end of June and pushed temperatures to exceptional levels across large parts of Spain. Before conditions had fully settled, another period of intense heat followed, extending the unusually hot weather well into July.

For many households, the biggest challenge hasn’t necessarily been reaching 40 degrees during the afternoon. It has been the feeling that the heat simply never leaves.

When the nights stop bringing relief

Anyone living in Spain knows that summer evenings usually offer a chance to recover after a hot day.

This year, many people have found that relief difficult to find.

One of the defining features of the summer so far has been the number of tropical nights, when temperatures stay above 20C until morning.

Without cooler air overnight, homes remain warm, bedrooms struggle to cool down and sleeping comfortably becomes much harder.

It is something many residents have noticed long before reading the official figures.

Air conditioning units have been working around the clock in many homes, while others have relied on fans, open windows and late evening walks simply to escape the heat indoors.

Health experts have repeatedly warned that warm nights can be just as demanding as very hot afternoons, particularly for older people, young children and anyone living with chronic health conditions. When the body cannot cool properly overnight, fatigue builds up over several consecutive days.

That is one reason this summer has felt so exhausting for many people.

The heat has spread far beyond Spain’s usual hotspots

Andalusia and parts of inland Spain are no strangers to extreme temperatures during July.

What has made this summer stand out is how widely the heat has spread.

Cities along the Mediterranean coast, which normally benefit from cooling sea breezes, have also experienced unusually high temperatures.

Barcelona exceeded 40C, an exceptional figure for a coastal city where the sea usually moderates summer extremes.

Further north, Cantabria also recorded some of the highest temperatures ever measured in the region.

In other words, this has not been a story limited to southern Spain.

Communities from the Mediterranean coast to northern regions have all experienced weather that has felt noticeably different from what many residents would normally expect.

According to climate specialists, the Mediterranean basin remains one of the areas in Europe most exposed to rising temperatures.

Cities including Valencia, Alicante, Murcia, Barcelona and Palma are already seeing longer periods of intense heat than they experienced in previous decades.

Some research also suggests that the cooling effect of the sea breeze may become less effective during certain weather patterns, allowing temperatures along the coast to climb higher than many people associate with seaside locations.

Why scientists are paying close attention

Researchers have long warned that climate change is increasing both the frequency and the intensity of heatwaves across southern Europe.

The Mediterranean has become one of the regions most frequently highlighted in international climate studies because warming is happening here faster than in many other parts of the world.

That does not mean every hot day is caused by climate change. It does mean that conditions favouring long, intense periods of heat are becoming more common.

The effects reach well beyond comfort.

Agriculture faces increasing pressure from rising temperatures and greater demand for irrigation. Dry vegetation also raises the risk of wildfires, particularly after prolonged heat combined with little rainfall.

Spain has already experienced repeated droughts, water shortages and destructive wildfire seasons in recent years, making every prolonged period of exceptional heat more difficult to manage.

What could the rest of summer look like?

Although this record only covers the period up to 15 July, summer is still far from over. Meteorologists have already warned that more episodes of very hot weather remain possible during the coming weeks, especially across eastern and southern Spain.

Whether new records are broken will depend on how the rest of July and August develop.

For many people, though, the statistics simply confirm something they already suspected.

The routines of everyday life have changed. Morning walks happen earlier. Outdoor work often starts before sunrise. Restaurants and cafés fill later in the evening. Parents look for shaded parks instead of open playgrounds during the afternoon.

People check overnight temperatures almost as carefully as daytime highs because they know that sleeping well can make all the difference after another scorching day.

Spain has always experienced hot summers. What feels different this year is how persistent the heat has been.

With AEMET confirming the hottest first half of summer since national records began in 1961, 2026 has already secured its place in Spain’s climate history, and for millions of people living through it, the numbers simply put into words what they’ve been feeling for weeks.
