When people move to Spain, they dream of sunshine, the sea, and a Mediterranean lifestyle. What many underestimate: summers in Spain – especially inland areas of Valencia – can be brutally hot. Temperatures above 40°C in the shade are not uncommon. In July 2025, parts of the Comunidad Valenciana recorded over 42°C – on several consecutive days.

For us, it was our first real heatwave in Spain – and also a valuable lesson in adaptation. In this post, we share how we manage daily life during extreme heat in Spain, what truly helps, and which mistakes are best avoided.

 

What Exactly Is a Heatwave in Spain?

 

In Spain, a heatwave – or “ola de calor” – is declared when temperatures remain exceptionally high for several days, typically well above seasonal averages. The definition varies by region, but in the Valencia area, an official heatwave is usually declared when daily highs exceed around 38 to 40°C for multiple days.

The Spanish weather agency AEMET issues warnings in three levels: yellow, orange, and red. This summer, several days reached red alert levels – with heat that brings everything to a standstill.

Why the Heat Feels Especially Harsh in Valencia

 

Although the Mediterranean coast is influenced by the sea, inland areas lack those cooling sea breezes. The sun beats down from above, nights offer little relief, and homes retain heat like brick ovens.

Then there’s the dreaded “Poniente”: a hot west wind that brings dry Saharan air. Instead of a fresh breeze, a scorching foehn wind blows through the streets – making every step feel exhausting.

Our Daily Life at 42°C – Heatwave Strategies in Spain

 

Home & Living: Passive Cooling Like the Locals

◉ Close shutters and blinds: Block out sunlight early in the morning, especially on south and west-facing windows.

◉ Cross-ventilate at night: Open windows when temps drop below 27°C – and don’t forget mosquito screens!

◉ Avoid heat-exposed rooms: Our bedroom faces south – we stay out of it during the day.

◉ Turn off lights: Every watt generates heat – LEDs are a must.

◉ Remove rugs and blankets: The less fabric, the better.

 

Technology: Using AC and Fans the Smart Way

◉ Use split AC strategically: Cool only selected rooms, not the entire house.

◉ Fan + ice trick: Place a bowl of ice in front of the fan – it can make the air feel 2–3°C cooler.

◉ Avoid peak energy use: No laundry or dishwashing between 1–5 PM.

 

Body & Nutrition: Staying Cool the Right Way

 

◉ Water, water, water: Drink 3–4 liters daily. Skip the alcohol.

◉ Eat light: Watermelon, gazpacho, salads – no hot meals at midday.

◉ Clothing: Light, loose cotton – or simply a siesta in a bikini.

◉ Cool your body often: Short cold showers, foot baths, wet cloths on the neck.

◉ Don’t forget electrolytes: Replenish sodium, potassium, and magnesium through drinks or food.

 

Gardening During a Heatwave – Our Observations

 

◉ Watering: Water plants early in the morning or late evening only

◉ Mulch the soil: Helps protect roots – especially for olives or tomatoes.

◉ Pool care: Cover the pool with a tarp when not in use to reduce evaporation.

◉ Cool your body often: Short cold showers, foot baths, wet cloths on the neck.

◉ Don’t forget electrolytes: Replenish sodium, potassium, and magnesium through drinks or food.

 

How Locals Deal with the Heat

 

Spaniards have decades of experience dealing with hot summers and handle the heat calmly and practically. The siesta isn’t laziness – it’s a time-tested survival tactic. Between 2 PM and 5 PM, everything slows down – and with good reason. Most activities simply shift to the cooler evening hours. Having dinner at 10 PM is completely normal and socially accepted in Spain.

Daily routines also adjust to the climate. The busiest hours are between 7 and 11 AM – then everything quiets down, both in the streets and in stores. Even clothing reflects this relaxed approach: flip-flops at a bank appointment or shorts at city hall? Totally acceptable when it’s 40°C in the shade.

Conclusion: Life in Spain Also Means Respecting the Sun

 

Heatwaves are likely to become more frequent – that’s the reality of climate change. Still, we wouldn’t trade life in Spain for anything. The sun is part of the package, and with the right mindset, even a heatwave becomes part of the adventure of starting a new life abroad.
