Taking care in the Sun
As can be observed, during Summer, the temperature in the Algarve is very high (it can go over 40ºC/100ºF exceptionally) and the periods of sun are long. It is common knowledge that excess sun can cause illnesses such as skin cancer.
The safest procedure is to use plenty of high-factor sunscreen, especially on children. A hat is an indispensable accessory, as are a good pair of sunglasses. It is advisable to avoid exposure to the sun during its strongest point in the day, between midday and 3 o'clock in the afternoon. In the case of sunburns or sunstroke, do seek medical attention.
