Aviso calor returns as Andalucía braces for extreme heat

Aviso calor returns as Andalucía braces for extreme heat

Spain's weather agency has activated a fresh aviso calor across western Andalucía after a brief cool spell, with yellow alerts today and orange warnings Tuesday as temperatures climb toward 40°C (104°F). Strong easterly winds and a hotter weekend—up to 44°C in Córdoba—raise heat-health risks.

Key Takeaways

Why did Spain issue a new aviso calor now?

According to Diario de Sevilla, the last week of July will again run warmer than normal across Andalucía. After a brief cold anomaly, a new anticyclonic ridge is set to drive temperatures up, especially from Tuesday. Monday 27 July brings stable skies—partly cloudy to clear—though smoke from inland wildfires may worsen air quality. Daytime highs stay notably elevated in the western Andalusian interior.

Aemet has posted yellow warnings this afternoon for the Córdoba and Seville countryside and for Andévalo and El Condado, where highs may reach 38°C. On the Huelva pre-coastal fringe, readings may hit 36°C. In the capitals, Córdoba and Seville may reach 39°C and Jaén 37°C. El Faro Motril reports yellow heat alerts Monday in Huelva, Cádiz, Seville and Córdoba, while Granada province starts the week without heat warnings.

How hot will Andalucía get this week?

Tuesday 28 July brings widespread tropical or equatorial nights—minima near 25°C in Cádiz and 24°C in Almería—plus rising daytime heat and Saharan dust. Orange alerts cover the Guadalquivir valley and inland Huelva, with highs up to 40°C. Yellow alerts extend to Sierra Morena, Córdoba's Subbética, the Genil basin and Almería's Poniente for 37–39°C. Capitals may hit 41°C in Córdoba and Seville and 40°C in Jaén.

Wednesday brings a slight western cooldown—Huelva near 29°C, Cádiz near 27°C—while orange alerts focus on Jaén and yellow on the Genil basin, with peaks near 40°C. Capitals may still reach about 42°C in Córdoba and 41°C in Granada. From Friday through the weekend, heat may intensify day and night, with minima around 25°C and Córdoba maxima forecast up to 44°C.

What else should heat-watchers know?

The other headline risk is strong levante wind. Diario de Sevilla notes locally strong winds in the Strait and La Janda, with very strong gusts up to 80 km/h, plus a coastal yellow wind alert for gusts to 60 km/h. Tuesday keeps yellow wind alerts for the Strait, with moderate-to-strong levante along the Almería coast.

Extreme-heat claims online remain a trap for longevity-minded readers tracking recovery and sleep. Newtral fact-checked viral posts saying Granada hit 50°C on 22 July during Spain's third heat wave (21–23 July). Aemet told Newtral forecasts were 42–44°C; Granada Airport reached 43.9°C, not 50°C. Spain's official record remains 47.6°C at La Rambla (Córdoba) on 14 August 2021, and street thermometers in direct sun can overread versus World Meteorological Organization standards.
