The Algarve has one of the mildest climates in Europe, with long, dry summers and gentle winters, so the best time to go depends on what you want to do. Here is how the seasons compare, so you can match the trip to the coast.
Spring (March to May): flowers, walking and fewer crowds
Spring is a favourite with hikers and photographers. The hills are green, wildflowers and almond and orange blossom colour the interior, and the cliff paths such as the Seven Hanging Valleys trail are comfortable to walk. Days are warm and often sunny, though the sea is still cool for swimming and the Atlantic can be breezy. Boat trips run, and caves are visited when the swell allows. Prices are lower than in summer, and attractions such as water parks are not yet open or run reduced calendars. Easter and school holidays are busier.
Early summer (June): the sweet spot
June brings long days, warm sunshine, a sea that is warm enough for most swimmers and fewer people than July and August. It is a very good month for boat trips to the caves and the Ria Formosa, for beaches and for family attractions as they move into full season. Evenings are pleasant and restaurants are lively without being full.
High summer (July and August): hot, busy and bright
These are the peak months. Temperatures are hot, especially inland, the sea is at its warmest and calmest, and the beaches, roads and car parks are at their busiest. Prices for hotels and tours are at their highest, with minimum stays at some resorts. Benagil and other caves book up, and popular beaches fill by mid-morning. Plan clifftop walks for early morning or evening, and carry water, a hat and sunscreen. Families with school-age children often have no choice, and the water parks, zoos and marine parks are at their best in these months.
Early autumn (September and October): warm sea and calm
Many regulars say September is the best month of all. The sea has been warming all summer and is at its warmest, the air is pleasant, the crowds thin and the light is soft. Beaches, boat trips, golf and walking are all excellent, and prices fall from August. October is more variable, with a chance of rain, but there are still many bright days and the first rains refresh the hills. Some seasonal attractions begin to reduce their open days, so check calendars.
Late autumn and winter (November to February): quiet and mild. Winter on the Algarve is gentler than much of Europe, with plenty of sunny days and temperatures that suit walking, golf and sightseeing, but rain comes in bursts and the sea is too cold for most swimmers. Boat trips run less often and caves are more frequently closed by the swell, so build in spare days. Many seasonal restaurants and some attractions close or reduce their hours, but towns such as Lagos, Faro, Tavira and Silves stay open, and prices are the lowest of the year. Almond blossom appears in late winter, and citrus is in season. It is a good time for travellers who want quiet, walking and value, and for anyone who likes to visit castles, churches and markets without queues. Pack layers, because mornings and evenings can feel cool indoors, where heating is often modest.
Choosing by interest
For beach days and swimming, choose June to September. For walking and photography, choose April, May, September or October. For boat trips and caves, summer is the most reliable but spring and early autumn are calmer and less crowded. For family attractions, aim for the full season between late spring and early autumn, and check opening calendars. For quiet and value, pick winter and accept some closures.
Sea and wind
The Atlantic is cooler than the Mediterranean, even in summer, and the west coast near Sagres is windier and cooler than the south-facing beaches of the central Algarve. Surfers like the west, and swimmers prefer the sheltered coves of Lagoa and Albufeira. Check swell and wind forecasts before booking boats or kayaks.
A simple rule
If you can choose, go in late May, June or September. If you have to travel in August, book early, start days early and keep afternoons for the shade or the sea. If you go in winter, bring a light waterproof, plan inland and town days, and enjoy the quiet.
