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.

A bit Brrrr this morning. At 730am my thermometer said 9.1C. Now, at 0930am it iis up to 12.3C.
The sun is up, there's not a cloud in the sky (looking south at least) and like in Dicey's pictures yesterday the light is so bright it almost hurts. There is the slightest breeze and it's dry air from inland.
This afternoon we should have 17C, staying bright and no clouds. Tonight will see temperatures down to 8 or 9 again.
Same for tomorrow, maybe a little cloud. From Thursday we will have slightly warmer days, perhaps back up to 20C in the daytime. That's 2 or 3 C above average for the time of year. And no rain is expected.

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.
