It's not warm in april-may, even if you would like to think so!
Toiletries and Medical Supplies: If you are sexually active, then remember this! Spain is a catholic country and you have to go to the doctor to get a recipie for emergency contraception pills! They also make you take a pregancny test before they give you he pills, and the medical insurance will not cover this visit! 135€ is a lot of money for a poor tourist! So if you can get them recipie-free from your home country always have them with you when travelling in catholic countries! And, boys and girls, remember the condom, but mistakes happen!
Camping/Beach/Outdoor Gear: The sun isn't that warm, but in spring the uv-light is very strong so you easily burn yourself in the sun! The water is icecold and you cannot go neither swimming nor lay on the beach because the wind from the sea is icecold as the water is.
