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 08:49 Daily Weather Report
It rained quite hard for a while last night. This morning started very grey, it's cleared up a bit but I can see a lot of cloud out to the west where the weather is coming from. Unfortunately the Loulé weather radar is broken yet again, although showers are forecast I cannot tell you where there are. Temperature at 0845am is 16.2ºC. With the cloud cover and likely rain, we are not likely to have more than around 20ºC today. That is though about average for mid October. Tonight it will be fairly cold, could be down to 12 inland, 14 or 15 along the coast. Tomorrow will be pretty similar to today, Saturday might be a little better, a touch warmer and dry. Sunday could be another rainy day, then for next week in southerly winds we could be having warmer and generally nicer days.

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.
