Inland capital, moderate UV in winter (4-5) and very high in summer (9-10). Altitude 667 m.
Sunburn occurs when the accumulated UVB dose exceeds your MED (Minimal Erythemal Dose), which depends on your Fitzpatrick skin type. Fair skin (I-II) has very low MED: in Madrid in summer, type II skin can burn in less than 15 minutes unprotected at solar noon.
Specific recommendations: wear a hat, seek shade during the middle hours, apply SPF 30-50 every 2 hours and check this index before planning outdoor activities. Children, elderly and people with very fair skin or photosensitising medication should be extra careful.
UVA radiation passes through clouds and glass: watch out on overcast days and in cars with closed windows. UV 400 sunglasses are essential to prevent early cataracts and macular degeneration.
