Best time to visit the Algarve: month by month

The Algarve, the south coast of Portugal, is one of the sunniest corners of Europe. Summers are hot and practically rainless, winters mild enough for walks in a T-shirt on many days. The Atlantic stays fresh even in summer, which makes the coast more pleasant than inland Spain in July – but it also means the sea is not as warm as the Mediterranean. We analysed the weather from 2015 to 2024 in Faro in the east and Lagos in the west.

The short answer

• Best time: May to June and September to October. 23 to 26 °C by day in Faro, long days, hardly any rain and fewer visitors than in high summer.
• High summer (July and August): 29 °C by day, almost no rain, but the beaches and resorts are at their fullest.
• Winter (November to March): mild at 16 to 19 °C by day – good for walking, golf and city trips, less so for swimming.
• Rainiest months: October to March, with peaks of 71 to 76 mm in March and October in Faro.

The Algarve's climate: all 12 months

Temperature and rain: monthly averages 2015–2024 from the ERA5 reanalysis (via Open-Meteo), rounded. A grid cell is about 25 km wide, so the values describe the coastal region around each town rather than a single beach.

Faro and Lagos are almost identical: the west around Lagos is a few tenths of a degree warmer by day and slightly cooler at night. The more noticeable difference on the ground is the wind – the further west, the more exposed the coast is to the Atlantic, especially around Sagres and Cape St. Vincent.

From June to September the Algarve is practically dry, with 0 to 15 mm a month. Rain comes in autumn and winter, often in a few heavy days rather than as constant drizzle; between them there are many sunny days.

The Algarve month by month

March to May

Spring is the best time for walking: the cliffs are green and in flower, and Faro warms from 18 to 23 °C. The coastal paths such as the Seven Hanging Valleys Trail near Benagil or the routes around Lagos are pleasant now. The sea is still cold. Around Easter, visitors from Portugal, Spain and northern Europe arrive.

June

For many the ideal month: 25.6 °C by day in Faro, only 7 mm of rain, long evenings and beaches that are not yet full. The sea slowly gets warmer, but it remains Atlantic-fresh.

July and August

High season. 29 °C by day on the coast; inland it gets considerably hotter. The beaches near Albufeira, Lagos and Portimão are very busy, and accommodation and hire cars^* need to be booked early. According to the UK travel advice, the wildfire risk in Portugal is increased from April to October, when it is hot and dry. Boat trips to the Benagil cave run most reliably in calm summer weather.

September and October

The second best time: September still averages 26.2 °C in Faro with hardly any rain, and the sea is at its warmest after the summer. The school holidays are over. October is still warm at 23 °C but brings the first autumn rain, with 76 mm on average in Faro.

November to February

Mild winter: 16 to 19 °C by day and around 10 °C at night. Not beach weather for most, but good for walks along the Ria Formosa lagoon, golf and the old towns of Tavira, Faro and Lagos. Some hotels and beach restaurants close; the larger towns stay open all year. More winter sun: where to go in January for sun.

The regions of the Algarve

Base map: Natural Earth

The east (Faro, Tavira) has long sandy beaches and lagoon islands, and is a little calmer. The centre around Albufeira is the busiest resort area. The west around Lagos and Sagres has the famous cliffs and coves, and further north along the west coast the wilder Atlantic beaches. With a car, Faro to Lagos is about an hour's drive.
