Both Spain and Croatia enjoy Mediterranean climates, characterised by hot, dry summers and rainy, cool winters. The temperature in Spain rarely drops below 23°C and can creep above 40 °C in the summer, while Croatia's summer temperatures range from 26°C to 30°C.

Generally, no; Spain is statistically warmer than Croatia throughout most of the year. While both countries enjoy a Mediterranean climate along their coastlines, Spain's southern regions (like Andalusia) and the Canary Islands provide a much hotter environment, especially in winter. In January, for example, Malaga might see highs of 17°C (63°F), whereas Split, Croatia, typically hovers around 10°C (50°F). During the peak summer months, both can be scorching, but Spain’s inland cities like Madrid and Seville often exceed 40°C (104°F), which is rarer in Croatia. Croatia’s climate is also more influenced by the "Bora" and "Sirocco" winds, which can bring cooler temperatures and rain more frequently than in the drier, more arid regions of southern and central Spain.
