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.

It's quite cloudy this morning, although the is up there, and it's also feeling rather damp. Temperature at 0930am is 16.9ºC, there is a bit of a breeze. The radar does show some large areas of rain down to the south and to the east in the bay of Cadiz. I am not sure whether they will come this way but it will be worth keeping a watch. Maximum temperature today 20 or21ºC.
Tonight won't be quite so cold as it has been.
Tomorrow will start cloudy with a chance of some light rain later in the day, temperature similar to today. Friday doesn't look too bad at the moment and the threat of rain over the weekend has been reduced. Temperature will stay around 20 - 22 until early next week but getting noticeably colder, more like late November should be, by the middle of next week. That means 16 or 17 in the daytime, could be as low as 7ºC at night.

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.
