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.
Today at 08:42 Daily Weather Report
It was very wild and wet last night. Strong gusts of wind with heavy, sometimes torrential, rain for most of the evening and well into the night. No thunder here though. (Further north the Europa League match between Estoril and PSV was abandoned at half time because of flooding.)
It's raining this morning, but nowhere near as hard as around 10pm last night. It's fairly cold as well, 13.4C at 0835am. There is a whole mass of showers, some heavy, swilling around to the south and west so it is going to be another very wet day. There is some blue sky out there just now but big black clouds are moving in.
Maximum today 16or 17C during breaks in the clouds. Saturday should be less worse but still with a few showers, then for Sunday we are forecast yet more heavy and thundery showers.
(I have the local news channel on in the background but so far no mention of weather or any consequences.)

What temperatures to expect along the year.
The sea water temperature starts at around 14ºC in January and reaches a high 22ºC in August. A pleasant sea breeze refreshes the average annual temperature of the region, which is 17,7ºC (15ºC in January and up to 28ºC or more in July and August).
The Algarve can also count on around 3.000 hours of Sun during the year which makes it a favourite destination for those who fancy such a delightful climate.
The interactive charts below will allow you to analyse the different average data that make the Algarve weather.
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.
