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 was indeed very hot here 'oop north yesterday, 27C in the afternoon. I was roasting, exploring all those Roman ruins. The pavement cafÃ©s in town were full at 5pm.
Today is set to be the same here, but a weather front is coming in from the Atlantic which will bring with it a lot of rain and much lower temperatures from Friday.
The same front will have an effect on the weather down south as mentioned by Dicey but it looks like the Algarve will miss out on the rain until Sunday. Still, it might not be all that nice for anyone flying on Friday and Saturday with all the weather about in the centre and north.
IPMA says 24 for Albufeira today and tomorrow, 21 on Saturday and very cloudy.

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.
