There will be ‘few places to hide’ from an intense heatwave that’s set to hit Spain from Sunday.

That’s the warning from state weather agency Aemet, which has issued a special weather alert for what will be the second official heatwave of 2026.

The scorching conditions, which will bring highs of over 42C to parts of Andalucia, is expected to last until at least Wednesday.

Aemet spokesman Ruben del Campo said the three criteria needed to classify an official heatwave – exceptionally high temperatures, widespread coverage and several consecutive days of extreme heat – will all be met from Sunday.

‘We’re already close to 40C in parts of Andalucia,’ Del Campo said, warning that the heat will become more widespread over the coming days.

He also highlighted another major concern: oppressive overnight temperatures, with tropical nights expected to make sleeping difficult across much of southern Spain.

‘The nights will be so warm that they will prevent people from getting proper rest,’ he warned.

The extreme heat will not be confined to Andalucia. Aemet says almost all of Spain, including the Balearic and Canary Islands, will be affected.

Temperatures are expected to exceed 38C in Mallorca on Monday, while southern parts of the Canary Islands could approach 40C.

‘This is a very extensive heatwave with few places where people can escape the high temperatures,’ Del Campo said.

Although the official heatwave is currently forecast to ease from Wednesday, Aemet stressed that this does not mean the heat will disappear.

Instead, temperatures are expected to remain well above average for the rest of next week, with many parts of Andalucia continuing to see highs of 35C to 40C.

The warning comes as southern Spain prepares for another spell of dangerous heat after an already exceptionally hot start to the summer.
