How warm is it in Costa Blanca during May?

Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.
