Spain in May is warm and mostly dry, with average highs between 22°C (Barcelona) and 28°C (Seville). Days are long and sunny, but evenings can be cooler near the coast. It is an excellent month for sightseeing before the summer crowds and heat arrive.
What temperatures can you expect across Spain?
Inland cities like Madrid and Seville reach the mid-to-high 20s °C by late May, while coastal destinations such as Barcelona and the Costa del Sol are a few degrees cooler thanks to sea breezes. Rainfall is low in most regions, though the north-west (e.g. Galicia) can still see some showers. Sea temperatures are around 17–19°C, pleasant for swimming but not yet balmy.
Is it warm enough for a beach holiday?
Yes, particularly in southern Spain. The Costa del Sol, Costa Blanca and the Balearic Islands enjoy plenty of sunshine and temperatures that feel hot by midday. If you are planning a beach-focused trip, pack light clothing, sun cream and a light jacket for the evening.
