The weather in the south is warmer than the north, meaning the only time of the year you really should avoid, are July and August. Seville is the hottest part of Spain, frequently seeing summer temperatures rise to 45 degrees.

No, Southern Spain is significantly hotter than Northern Spain, particularly during the summer months. Northern regions such as Galicia, Asturias, and the Basque Country have an Atlantic climate, characterized by mild temperatures and frequent rainfall. In July and August, daily highs in the north typically range from 20°C to 25°C (68°F–77°F), rarely reaching the extreme heat seen elsewhere. In stark contrast, Southern Spain, especially the inland cities of Andalusia like Seville and Córdoba, experiences a Mediterranean climate that can be punishingly hot. In the peak of summer, these cities regularly see temperatures soaring above 40°C (104°F), often earning the region the nickname "the frying pan of Europe." Even in winter, the south remains much milder, with highs often reaching 15°C to 18°C, while the north stays cool and damp around 8°C to 12°C. For travelers, this means the north is a lush, green paradise ideal for hiking and escaping the heat, while the south is the land of dry, golden landscapes and intense sunshine, making your choice of destination entirely dependent on your tolerance for high temperatures and sun.
