A practical May plan
Combine a beach around Maspalomas with the dunes, or reserve a separate day for Las Canteras and Vegueta.
The southern resort coast, Las Palmas and the mountain interior have different exposure and elevation; this coastal point is not an island-wide forecast. Check an up-to-date forecast before travelling and the beach flags before entering the water. These air-temperature figures do not tell you sea temperature, wind speed or whether swimming is safe.
