El viernes no pude dormir. En Sevilla fue la noche más calurosa del verano y del año. El jueves España marcó la temperatura más alta del año: 45,1 grados.
Este verano ha causado más de 5.200 muertes prematuras por las temperaturas extremas. También ha roto más de 300 marcas históricas en muchas provincias. Hubo noches tropicales con 39 grados a medianoche, como el 19 de agosto en la Comunidad Valenciana.
Además, este año hemos visto el abril más cálido y el junio más caliente en Europa occidental. Los océanos también están muy calientes. Mallorca marcó 33,2 grados en el mar Mediterráneo. Todo esto es muy preocupante.

Watch out, English speaker
English speakers often use the imperfect (dormía) when they should use the preterite (no pude dormir) for a specific, completed past event. In Spanish, the preterite is required when the action has a clear endpoint, as in El viernes no pude dormir.
When forming superlatives, English uses 'in' (the hottest night in the year), but Spanish uses de: la noche más calurosa del año. A common mistake is to use en, which is incorrect in this structure.
Spanish adjectives must agree in gender and number with the noun, unlike English. For example, caluroso changes to calurosa for a feminine noun like noche, and to calurosos for plural masculine nouns. Forgetting this agreement is a frequent error.

Extreme Heat in Spain
Spain is often affected by hot air from Africa in summer, and temperatures in the southern region of Andalusia frequently exceed 40 degrees. In recent years, heatwaves have become more frequent. In 2022, Seville became the first city in the world to name and rank heatwaves in order to alert the public to the risks of extreme heat.
