The proximity of the Mediterranean Sea greatly influences the Algarvian climate. Summers are hot and dry and winters are mild with hardly any rain (50 days with rain and 500 mm on average each year), combined with very inviting springs and autumns.

Quite possibly it was 36C in the direct sun. The thermometer in my front room was showing 30C yesterday afternoon and it is a little in the shade.
It's going to be hot again today, possibly 30C. Temperature at 835am is 23.6C, humidity at 47%. It's a bit misty out to sea but blue sky overhead. The wind is very light.
Tonight will be another warm one, no lower than about 20C. Tomorrow could be even hotter than today, 32 or 33C, as the lump of hot air passes over, then it starts to cool down again and by the weekend it could be as cold as 25C in the daytime, 15 or 16 at night.
No rain is expected for the next several days.

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.
