Cut through the noise: is the rainy season really the main factor here in Spain? Families often prioritize the total cost and the availability of school holidays. If the price is very low and it's the only window to travel, the weather becomes secondary. The simplicity is that budget and schedule take precedence; for example, a cheaper flight to the Canary Islands during a "rainy" period but with mild temperatures often outweighs the idea of perfect weather but higher cost.
