What's the weather like in the Algarve in August

July and August are the hottest months of the year in the Algarve region, and also the sunniest and driest. Due to the decreasing daylight amounts, August has slightly less sunshine than July, with an average of 353 hours of bright sunshine at the region's capital, Faro, which comes out at a mean between 11 and 12 hours per day. The daytime temperature reaches an average high of 29°C, and falls to an average of 19°C overnight.


Although temperatures mostly stay close to the long-term average, major heat waves occasionally crop up and temperatures well in excess of 35°C have been recorded. There was a severe heat wave at the end of July 2003 and during early to mid-August 2003 (a heat wave which also consumed most of the rest of central and Western Europe) which contributed heavily to widespread mountain fires.

The 2003 European heat wave was the hottest summer on record in Europe. August 1st, 2003 was the hottest day recorded in centuries, with night temperatures exceeding well above 30°C. Over the next coming weeks a strong and hot Sirocco wind contributed to the spread of extensive forest-fires. Over 5% of the Portugal's countryside and 10% of the forests were destroyed due to the wild fires. It is also estimated that approximately 18 people died in the flames in the whole of Portugal and temperatures as high as 48°C were recorded in some areas of the country.


Many Augusts are completely free from rain, especially near the coast, but on rare occasions short-lived thundery downpours crop up. On average there is only one day per August with measurable rainfall at Faro, with a mean monthly total of 4mm.

The probability of precipitation at this time of year is very low at only 3% to 8%, compared to January where rainfall is 36% likely. Over the entire year the most common forms of precipitation are moderate rain, light rain, thunderstorms and drizzle. August also lies within the warm season, which lasts from June 23rd to September 14th. During this period of time there is a 6% average chance that precipitation will be observed at some point during a given day. When it does occur usually it is mostly in the form of moderate rain (45% likely).


Humidity at this time of year is generally low; the relative humidity typically ranges from a comfortable 41% to a humid 87%. The air is typically driest around July 12th, at which time the relative humidity drops just below 50%, which is still considered comfortable. The most humid time of the year is around January 3rd where humidity levels can exceed 94%, which is considered as very humid. One thing to bare in mind is that humidity levels are usually lowest when temperatures are high.

The dew point is often a better way to measure how comfortable a person will find the weather than relative humidity levels, as it relates to whether perspiration will evaporate from the skin. Lower dew points tend to feel drier and higher dew points usually feel more humid.  There are two periods in the year that are most comfortable: the first is between January 1st and July 13th and the second is between September 15th and December 31st. August does not lie in between either of these periods and can be relatively muggy at 12°C to 19°C.


Throughout the year typical wind speeds vary from 0 m/s to 8 m/s, which is a calm to moderate breeze, rarely ever exceeding 11 m/s. During August the average wind speed is a low and calm 3 m/s. Compared to April 7th, at which time the average daily maximum wind speed can reach 8 m/s.

Cloud cover at this time of year generally very clear. The sky is usually cloudiest in the Algarve on January 1st and clearest on July 26th. The clearest part of the year begins around June 3rd and lasts up until the end of September. 

Average Sea Temperature

The sea temperature off the coastline is at its warmest during August and September, peaking at around 21°C on average, so this is a good time of year to try swimming or diving off the Atlantic coast.

Algarve Hotels in August

There is a lot of good accommodation available in the Algarve region. The Hotel Da Rocha at Praia da Rocha, Portimao is situated right across the beach, making it a good beach resort hotel, and the 4-star accommodation is relatively inexpensive.

Luxury 5-star options include the Cascade Resort at Praia do Canavial, Lagos, which also offers a range of activities that are particularly geared towards families. The PortoBay Falesia at Quinta do Milharo, Albufeira is another good beach option which offers good 4-star accommodation.

Alternatively, Quinta da Nina at Rua do Moinho da Encarnacao 1, Lagos, is a good value bed and breakfast option, while those who would prefer self-catering can consider the Vilabranca Apartments at Torraltinha, Lagos.

Algarve Beach for August 

August is the most popular time of year to visit the beaches, so some of the more popular beaches can end up quite crowded, but the beaches at the Algarve are so numerous that it is usually possible to find a relatively quiet spot.

For those who would prefer a relatively secluded location, Ilha de Culatra is an island situated off Olhao, and being off the mainland, does not attract as many tourists as some of the other resorts, while boasting pleasant beaches.

Praia Gale, 4 kilometres west of Albufeira, contains soft sands that are suitable for small children, and a range of reasonable restaurants. On the other hand Arrifana Beach is another popular option for young families. This blue flag beach is approximately 500m long and is located within the Vicentine Coast Natural Park. 

Bars and Restaurants

The Algarve region boasts a large number of good restaurants, some of which are also relatively inexpensive. Fin du Mundo at Rua Manuel Teixiera Gomes No 28, Ferragudo is a good option for both English and Portuguese-style food, and there is a strong emphasis on seafood, so most tastes should be catered for. Fans of Italian restaurants should consider L'oasis Pizzeria Italiana at Edificio Atlântico IV, Armacao de Pera, which is particularly known for its good pizzas.

The Algarve region also has a large number of traditional British-style pubs which offer pub food, and evening entertainment. Roskos at Rua Candido dos Reis N0 79, Lagos has frequent musical performances on evenings, which include funk and rhythm and blues. For some good and varied cocktails, Mourisco Cocktail Bar at Alvor, Portimao is easy to recommend, and this bar, too, features musical entertainment on evenings.

Things to do in Algarve in July 

August is a good time of year to try diving off the Mediterranean coastline. UDiving Dive Centre, which has two main centres at Faro and Tavira, is one good centre for divers, as it offers dive trips and also training courses for the benefit of novices, plus intermediate divers who would like to improve their skills. Those into scuba diving are particularly well catered for. A good alternative company is Exclusive Divers, located at Alvor, Portimao, who also offer diving courses, including dives to sites with famous shipwrecks, and they, too, focus especially on scuba diving.

There are some good natural attractions and landmarks in the Algarve. The Fortress of Sagres at Sagres on the coast of the Algarve is impressively mainly for its views over the nearby bay and ocean. There is an exhibition centre contained within, and on a good day, local fishermen can be spotted fishing around the nearby coastline.

The Camera Obscura at the Tower of Tavira gives a very good view of the town of Tamira. Guides present informative discussions about the laws of optics, as established in the paintings of Leonardo da Vinci, and technological gadgets showing panoramic views of the area.
