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.

I am returned, to a morning of scattered high clouds, a bit of an easterly breeze and temperature of 19.8C at 0845am.
It will stay cloudy and fairly breezy all day, there is no immediate threat of rain but there might a light shower or two tonight. Maximum temperature later of 24 or perhaps even 25C, still way above average. Tonight will be a comfortable 17 or 18C.
The wind will shift around to come from the north tomorrow, bringing clear skies and another day of 25C, but from Monday the weather becomes more like November should be with much cooler temperatures (18 to 20C in the daytime, 13 or 14 at night) and a lot of showers for Monday and Tuesday especially.

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.

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.
