Temperatures in Jaen are generally among the coldest of Andalucia, although the variations are extremely huge. From a maximum of 35ºC in summer, temperatures can drop to an average of 5ºC in winter months.

The coldest place in Andalucía during the blistering summer months is the Sierra Nevada mountain range in the province of Granada. Specifically, the peaks near Pradollano or the summit of Mulhacén (the highest point in mainland Spain) maintain temperatures that are 15°C to 20°C cooler than the valleys below. While cities like Seville or Córdoba can reach a sweltering 45°C in July, high-altitude villages like Trevélez (the highest village in Spain) often remain in the comfortable 20-25°C range during the day and can drop to 10°C at night. If you are looking for a coastal escape, the Cádiz coast (near Tarifa) is the coolest seaside option due to the strong Atlantic winds known as the Poniente, which keep average summer highs around a manageable 26°C. These "cold spots" are the preferred refuge for locals seeking to escape the "frying pan of Europe" during the peak heatwaves of 2026.
