Climate
Spain is known for its long hours of sunshine all year round (more than 2,000 hours on average, varying by region), making it one of the warmest countries in Europe, so you won't need your umbrella very much. In fact, although there are different climates (Atlantic or Oceanic, Continental, Mediterranean, etc.), the mild Mediterranean climate is predominant, and even going out for a walk during the evening is pleasant in Spain.
It is important that you take into account that you will find strong differences depending on the time of year you come and the part of the country you are travelling to. While inland and in the mountain areas winters are cold and summers are hot, on the coast the temperatures are milder throughout the year. The Canary Islands are an exceptional case (as they are situated off the coast of Africa) – their average year-round temperature on the coast is 22ºC, and does not vary excessively. As for rain, it is more abundant in the north and north-west than in the rest of Spain. The south-east is the driest area.
If you are coming in summer… The sun shines in most of the country and temperatures vary between 25 and 35ºC approximately. We recommend bringing light clothes and something warm for the night.
If you are coming in autumn… The weather can be more changeable and temperatures vary between 15 and 20ºC approximately.
If you are coming in winter… In general, Spain does not suffer from extremely cold temperatures, although inland and in mountain areas they do drop significantly (and it even snows). They vary between 2 and 15ºC approximately. Bring warm clothes.
If you are coming in spring… Temperatures are pleasant (between 10 and 22ºC approximately), but it may rain.
We recommend checking the weather forecast for the town you are going to on the official website of the National Weather Agency (AEMET):
