Portugal's southern coast is a 200-kilometre line of golden cliffs, sea-cut grottoes and broad sandy beaches, with a hinterland of cork forests and whitewashed villages. The Algarve has the longest reliable beach season in continental Europe outside of southern Spain, helped by an Atlantic exposure that keeps summer humidity low and a microclimate locals call 'three hundred days of sunshine' — close enough to the truth.
May to early July and September are ideal. The water is bracing rather than warm — Atlantic, not Mediterranean — but air temperatures and sunshine hours rival anywhere in Europe. October stays warm for sightseeing and golf.
Winter highs hover around 16-17°C with mild nights and modest rainfall — about eight to ten rainy days a month from December to February. The region attracts long-stay visitors and golfers who want sun without heat. The Atlantic is too cold for swimming but the light is extraordinary.
Wildflowers across the cliffs from late February. By April daytime temperatures reach the low twenties, the almond blossom and citrus groves are at their best, and the trails along the Rota Vicentina open up before the summer heat. Sea temperatures stay around 16-17°C — too cold for most.
June through August brings 28-30°C days, near-zero rain, and twelve hours of sunshine. The Atlantic sea temperature finally creeps to 21-22°C, which feels refreshing rather than warm. Western beaches near Sagres are noticeably windier and cooler than the sheltered eastern coast around Tavira.
September is exceptional: sea at its warmest (22-23°C), air still around 27°C, and crowds gone after the first week. October keeps mid-twenties highs and is the favourite month of golfers and hikers. By November the first Atlantic fronts arrive and the season winds down.
By Mediterranean standards, yes. Sea temperatures peak at 22-23°C in August and September. Sheltered eastern beaches are a degree or two warmer than the exposed west.
March, April, October and November combine warm-but-not-hot weather, dry fairways and shoulder-season green fees. Summer is too hot for most rounds.
Very. Portuguese and Spanish school holidays both fall in August. Albufeira and Lagos are busy from breakfast onwards. Tavira and the Costa Vicentina stay calmer.
Yes — one of the warmest winter regions in continental Europe, with daytime highs around 17°C and frequent sunshine. Many golfers and long-stay retirees base here from November to March.
