Summer 2026 has become a true test of resilience for Spain. The country is trapped in a massive and dangerous heatwave that threatens not only local residents but also thousands of tourists who have arrived on the coast. Meteorologists have recorded unprecedented figures: in several regions, air temperatures could soar to a record 47 degrees Celsius.

Red danger zone

The situation in the south and southeast of the country is assessed as critical. It is here, in Andalusia and Extremadura, that the meteorological agency AEMET has issued red warnings — the highest level of danger. Orange alert signals, indicating a high risk to health, are in effect in Madrid, Aragon, Catalonia, and Castile-La Mancha.

Extreme weather shows no signs of leaving: the heat will last for at least several days, significantly increasing the risk of large-scale wildfires that could break out at any moment.

'Heat dome' and dust storm

The cause of the anomaly is the so-called 'heat dome' — an atmospheric phenomenon that traps dry, scorching air from the Sahara over the Iberian Peninsula. This is already the third significant heatwave of the season, and it has turned out to be one of the most powerful.

In addition to suffocating temperatures, Spain has been covered by calima — a dense dust veil brought by winds from the desert. This phenomenon not only reduces visibility and air quality, making it dangerous to breathe, but also creates a thermos effect, preventing nights from cooling down properly.

Survival rules during anomalous heat

The state meteorological agency AEMET strongly recommends that all travelers observe strict safety measures. The most dangerous time of day remains between 12:00 and 17:00. During this period, experts advise:

  • Minimize exposure to direct sunlight.
  • Stay in cool, air-conditioned rooms.
  • Drink plenty of water to avoid dehydration.
  • Avoid any intense physical activity.

Particular vigilance must be exercised by the elderly, pregnant women, children, and those whose work involves being outdoors. In 47-degree heat, even a short walk can be fatal for an unprepared body.
