Summer Heat in Madrid… What to do
Last year we had 57 days on a row above 35Cº/94Fº and the sun will be up until 21:30-22:00. You should avoid being outdoor during the central hours of the day. From 15:00 to 18:00 it is better to stay at your hotel and enjoy Spain’s most practical custom: The unique and only Siesta.
In any case you should drink a lot of water, take advantage of shades and protect your head with a hat and your skin with sun cream. You can also buy a useful souvenir: the fan.
