Will Spain’s third heatwave be as bad as the last one?

Spain has already faced two scorching heatwaves so far this spring and summer, but with meteorologists predicting a possible third in the coming days, could it be as bad as July's?

As Spain moves into August, the stifling temperatures look set to stay.

Record temperatures have caused forest fires across the country, killed people by the hundreds, forced large swathes of the population to stay inside all day in order escape the heat, and ‘tropical nights’ have made sleeping incredibly uncomfortable.

But will these temperatures continue throughout August?

With unnaturally warm temperatures continuing over the last weekend in July, experts are now considering whether the duration and intensity of the latest round of scorching weather will be enough to qualify as Spain’s third official heatwave (ola de calor) of the summer and how long it will last.

With high temperatures predicted for the first week of August, if they continue further into the month, it is likely AEMET (Spain’s state meteorological agency) will declare a third heatwave, although, spokesman Rubén del Campo says it is looking likely to be “less intense and extreme than the previous two”.

For meteorologists to officially consider scorching weather to be a heatwave, the period of extreme heat must last at least three days and temperatures must exceed seasonal thresholds by 10 percent.

“It is possible that from last Sunday July 31st until at least Wednesday August 3rd or Thursday 4th, the thresholds of intensity, persistence and extension necessary to be able to catalog this episode as a heat wave will be exceeded,” the meteorologist added.


According to AEMET forecasts, temperatures climbed on Monday August 2nd and Tuesday 3rd but will begin to decrease from Thursday.

High temperatures could continue for most of week, however. “In large areas of the interior of the northern half,” del Campo said, “and also in points in the centre and south, temperatures will be between 5C and 10C above normal for this time of year.”

One thing that won’t change, however, regardless of whether AEMET declares the heat an official heatwave, is the sweltering night temperatures. 

August temperature forecasts across Spain, showing the areas expected to be ‘warmer than normal’ (más cálido de lo normal), ‘slightly warmer than normal’ (ligeramente más cálido de lo normal) ‘quite a bit warmer than normal’ (bastante más cálido de lo normal) and ‘much warmer than normal’ (mucho más cálido de lo normal).

The phenomenon of ‘tropical nights’, when temperatures stay above 20C during the night, have now become the norm up and down the Mediterranean coast and southern half of the country.

In some cases, temperatures through the night have hovered around 25C, making it very difficult to sleep or save on electricity bills.

Spain’s previous heatwaves in 2022

The first heatwave began early this year, back on June 11th, and lasted almost a full week (officially until June 18th) and was the earliest heatwave Spain had suffered in almost fifty years, affecting 38 provinces across the country.

Incredibly, in places in southern Spain like Jaén, a staggering 44.5C was recorded on June 17th – far earlier than expected and is normal.
In mid-July, however, the second heatwave was much more intense – the third longest in Spanish history and the most severe.

Temperature surpassing 40C spread across the country, affecting even the northernmost areas such as Galicia and Asturias, with the mercury touching 45C in the south, and killing over a thousand people.

  1. In some earlier articles you mentioned leaving windows open at night. Good idea, but please make sure you have efficient fly/mosquito screens at the windows so that you are not at the mercy of the mozzies, moscas negras etc. My husband neglected to do this when he first came to Spain and slept with the balcon open to the stars; he was unrecognisable the next morning, his face etc (and I mean etcetera!) were so swollen and not in a good way!
    Also, the moths! Our village is nicknamed Velilla de potilla because we get plagues of moths. (Ribero Bajo de Aragon)

640 flights cancelled as storm Hermine hits Spain’s Canary Islands

Torrential rains and high winds prompted the cancellation of more than 640 Canary Islands flights over the previous 36 hours, Spain's AENA airports operator said on Monday.

640 flights cancelled as storm Hermine hits Spain's Canary Islands

Most of the cancellations took place on Sunday, when 540 flights to and from the Atlantic archipelago had to be axed and another 54 rerouted as tropical storm Hermine battered the islands.

By 8:40 am (1040 GMT) on Monday, another 102 flights to and from the islands had been cancelled while six others were re-routed to other destinations, AENA said in an update on Twitter.

Most of the cancellations affected the two airports on Tenerife, the largest of the Spanish islands, which are located off the northwestern coast of Morocco.

AEMET said the rain would continue on Monday but would be “less intense” than at the weekend, saying the downpour had resulted in the islands’ “wettest
September on record”.
