Lagos shares the Algarve headline numbers, around 3,000 hours of sun a year and summers with essentially no rain, but with a western twist. Sitting closer to the Atlantic corner of the coast, it catches more of the northerly wind that wraps around the Sagres headland, so summer afternoons are usually a pleasant 27–28 °C, a touch fresher and breezier than in the central Algarve resorts.

The same west-facing position affects the sea. Summer winds pull deep, cold water toward the surface along the west coast, so the ocean at Lagos typically peaks around 19–21 °C, one or two degrees below the eastern Algarve. Winters are mild and bright, with 16 °C sunny days the norm and rain confined to short spells between November and February.

Averages for 2016–2025, based on ERA5 historical data from Open-Meteo. A rainy day is one with at least 1 mm of precipitation.

Why is the sea colder in Lagos than in the eastern Algarve?

Summer northerlies push surface water away from the west coast and draw cold deeper water up to replace it. Lagos sits close to that upwelling zone, while beaches further east are sheltered from it and warm up more.

When is the sea warmest in Lagos?

In August and September, when it reaches roughly 20–21 °C after a summer of heating. A few days of strong westerly wind can temporarily cool it several degrees at any point in the season.

Does it rain in Lagos in summer?

Almost never. From June to September measurable rain falls on only a handful of days, which is why the western Algarve can promise sunshine with such confidence.
