Is September hot in Spain? The answer largely depends on your personal perception of heat. For those arriving from colder climates, September feels delightfully warm, providing ideal conditions for a holiday. Even for those sensitive to high temperatures, the summer extremes of 95–100°F ease into a more comfortable range of 75–85°F.
