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 not as hot as yesterday, 29.5C at 1145am but rather more humid. Skies are blue overhead but it is rather murky out to sea. Not sure if that is dust or fog. There is a light breeze.
The official forecast has a maximum today of 27 along the coast but much hotter inland away from the sea breezes.
It might be a bit cold tonight, down as low as 21C on the coast.
The next couple of days might be a little cloudy but temperatures still in the high 20's, about the normal for the time of year. Further ahead, the predictions are for another few days of very hot weather, back up to 38C by the weekend perhaps.

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.
