Vila Nova de Milfontes stands where the Mira river meets the Atlantic, inside the Southwest Alentejo and Vicentina Coast Natural Park. It is one of the classic Portuguese summer destinations, packed with domestic holidaymakers in August and quiet the rest of the year. The river beaches, Franquia above all, are calm and sheltered, while the ocean beaches out by the Farol are open to the full swell.
Summer afternoons usually reach 25–28 °C, with a northerly wind that builds after lunch and drops again in the evening. Winter is mild at 15–16 °C, with rain in Atlantic spells. This is west-facing coast, so upwelling keeps the ocean cool through the summer at around 16–18 °C, while the shallow river water behind the sandbar can feel several degrees warmer.

In September, once the summer northerly eases and the upwelling relaxes, when the ocean reaches about 17–19 °C. For a warmer swim at any point in the season, use the river beaches: the Mira estuary is shallow and sheltered and always ahead of the open sea.
The river for calm water, safe paddling and warmth, the ocean for waves, space and sunsets. Franquia, on the estuary, is the family choice and is protected from the afternoon wind. The Atlantic beaches by the river mouth have currents and shorebreak, so swim near the lifeguards.
June and September are the sweet spot: warm, uncrowded and with the sea at its best in September. August is when the whole country arrives, so book months ahead and expect the beaches and restaurants to be full. Outside summer it is a quiet base for walking the cliffs inside the natural park.
