Algarve Weather Month by Month
Practical Info
The Algarve enjoys one of the most favourable climates in Europe, with over 3,000 hours of sunshine a year and average temperatures that rarely drop below 10 degrees Celsius even in the coolest months. Understanding the month-by-month weather patterns is essential for planning a visit, whether the aim is beach holidays, walking, golf or exploring the region's cultural heritage.
January and February are the coolest and wettest months, with average daytime temperatures of 15 to 16 degrees and overnight lows of around 8 degrees. Rain falls on approximately 6 to 8 days per month, though periods of bright, clear weather are common between the rain. The almond blossoms appear in late January and early February, transforming the Barrocal hinterland. These months are excellent for walking, birdwatching and cultural exploration, with very few tourists and correspondingly lower prices.
March brings noticeably longer days and warmer temperatures, with daytime highs reaching 18 to 19 degrees. Rain becomes less frequent, and the countryside is at its greenest. The wildflower season begins in earnest, making March one of the best months for botanical walks and photography. Easter, when it falls in March, brings the first significant influx of visitors.
April and May see temperatures climb to 20 to 23 degrees, with rain becoming increasingly rare. The sea temperature, still cool at around 16 to 17 degrees, begins to warm. These months offer what many regular visitors consider the ideal Algarve conditions: warm, sunny days without the intense heat of summer, quiet beaches and countryside carpeted with wildflowers.
June marks the transition to summer. Daytime temperatures reach 25 to 28 degrees, and rain is virtually absent. The sea warms to around 19 to 20 degrees. Tourist numbers begin to increase, particularly in the second half of the month, though the Algarve is not yet at peak capacity.
July and August are the hottest months, with daytime temperatures regularly reaching 30 to 35 degrees and occasionally exceeding 40 degrees during heatwaves. The sun is intense, and UV levels are high. The sea reaches its warmest at 21 to 23 degrees. These are the busiest months for tourism, with beaches, restaurants and accommodation at full capacity. The west coast and Costa Vicentina are typically several degrees cooler than the sheltered south coast, with a refreshing Atlantic breeze.
September is widely regarded as one of the best months to visit the Algarve. Temperatures remain warm at 26 to 28 degrees, the sea is at its warmest, and the summer crowds have thinned considerably. Rain is extremely rare. Many returning visitors time their trips for September.
October sees the first autumn rains return, though they are typically brief and interspersed with long sunny spells. Temperatures of 22 to 24 degrees remain comfortable for outdoor activities. The sea, still at around 20 degrees, is warmer than the English Channel in high summer.
November and December bring cooler conditions, with daytime temperatures of 17 to 19 degrees and increasing rainfall. December is typically the wettest month. However, clear, sunny days are still frequent, and the mild winter climate attracts a growing number of long-stay visitors from northern Europe seeking to escape the cold.
