Things to Do in the Algarve in May: What's Worth It
May in the Algarve brings warm, green days and quiet beaches before the summer crowds. Here are the walks, boat trips and towns that suit the month.

May is the month the Algarve stops hedging. Daytime highs typically sit around 22–24°C, the landscape is still green rather than parched, and the beaches stay noticeably quieter than in July and August, which makes it one of the most usable months for both walking and lazing outdoors.
The trade-off is small and specific: evenings cool off enough to need a layer, and the sea lags well behind the air. Plan the trip around the land rather than around swimming, and May rewards you.
Is May a Good Month for the Algarve?
Yes, for most trips. May gives you reliable sun without the 30°C-plus afternoons that build through summer, which means cliff walks, town wandering and long terrace lunches all happen comfortably in the same day.
It suits walkers, couples, families with young children and anyone who wants the coast before it fills. It suits swimmers less well, and anyone chasing guaranteed heat should look at June or later. If you are still weighing months, the best time to visit the Algarve lays out how April, May and June differ.
Weather in May
Expect average daytime temperatures in the low twenties Celsius, feeling warmer in direct sun, with nights cool enough for a jumper or light jacket once the sun drops. Rain is infrequent, and any showers tend to be short rather than day-ruining.
The sea is the honest caveat: it is still on the cool side in May, so treat swimming as a quick dip or paddling rather than long sessions, and judge it for yourself once you feel the water. That lag between air and water is exactly why the coastal paths and hill trails are the stronger May choice.
Early vs Late May
Late May is warmer and reliably drier than the first week, and the sea has had more time to lose its winter chill. If your trip is fixed in early May, weight the days towards walking, towns and inland drives rather than long beach afternoons.
The bigger shift is commercial: through the month, boat trips, beach bars and coastal restaurants move from reduced pre-season hours towards full summer operation. Book water-based outings through operators who list their May sailings and confirm timing when you book.
Walk the Seven Hanging Valleys
The clifftop route between Praia da Marinha and Carvoeiro is the Algarve's signature walk, threading above sea arches and limestone stacks. May is close to ideal for it: the sun is strong but not punishing, and the path is far less busy than in August.
Start early from Marinha, carry water, and give yourself most of a morning rather than rushing it. The same coastline appears in our guide to Praia da Marinha, which is worth reading if you want to build a beach stop into the walk.
Ponta da Piedade and the Lagos Coast
The rock formations and stairways at Ponta da Piedade, just south of Lagos, are a natural half-day: a short clifftop circuit plus time on the small coves below. In May you can move at your own pace without the summer queue at the viewpoints.
Pair it with the old town in Lagos for lunch, then use the afternoon for the sheltered south-coast beaches, which handle a breezy day better than the exposed west.
Beaches and Breezy Days
South-coast beaches between Faro and Portimão are the safer bet when the wind picks up, since the cliffs and bays break it. The west coast around Sagres and Aljezur is wilder and windier, best saved for the days you want dramatic scenery rather than sunbathing.
May is warm enough for sunbathing and sandcastles, and beaches are much quieter than peak summer, so parking and space are rarely a problem.
Benagil Cave and Boat Trips
The Benagil sea cave is the Algarve's most photographed sight, and the only realistic way in is by water or by kayak and paddleboard tours that launch nearby. May's calmer, quieter conditions make it a better month for this than high summer.
Departures run from Albufeira, Portimão and Lagos, with options ranging from short cave runs to half-day cruises towards Ponta da Piedade. Compare what each trip actually covers before booking, because the distances between departure points change the itinerary substantially.
Inland: Monchique and the Hills
The wooded Serra de Monchique behind Portimão is the antidote to a hot coastal afternoon, with cooler air, cork oak and viewpoints over the coast. Foia, the range's high point, gives you the whole Algarve in one view on a clear May morning.
Combine it with a spa town stop in Caldas de Monchique and a long lunch of local chicken and honey cake, then drop back to the coast for the evening.
Cape St Vincent and the West
Cabo de São Vicente, the south-western tip of Europe, is a straightforward day out from Lagos: lighthouse, cliff edges and big Atlantic views, with Sagres a short drive away. It is windswept even in May, so treat it as a scenery stop rather than a beach day.
Birdwatchers should head for the Sagres headland, which sits on a major migration route, and the quieter west-coast villages such as Aljezur reward a slow afternoon.
Eating and Drinking in May
May is a good month for the table: fresh fish and shellfish are at their best before the summer rush, and terraces are warm enough for dinner outside in the early evening. Grilled sardines, clams and cataplana all feel right now, as do the region's young wines.
Estate visits around Lagoa and Portimão are easy to arrange in May, when tasting rooms are quiet and the vineyards are still green.
Crowds and Prices in May
May is shoulder season: busier than winter but far below July and August levels, with accommodation, flights and car hire generally cheaper than high summer. Resorts and popular towns are quieter, and restaurants are mostly open in the main beach areas.
Watch the UK bank holiday weekends and half-term, which tighten availability on the coast; if your dates are flexible, midweek in the middle of the month is the calmest window.
May or June?
Choose May for walking, greenery, quieter towns and lower costs, and accept a cooler sea and cooler evenings. Choose June for warmer water, longer beach days and a livelier resort scene, and expect prices and crowds to climb.
If you are set on April instead, our guide to the Algarve in April covers the cooler, greener version of the same trip, and where is warm in Europe in April helps you compare alternatives across Southern Europe.
The Verdict
May is the Algarve's most useful month for a mixed trip: walk the Seven Hanging Valleys early, take a boat to Benagil while the water is calm, and keep the afternoons for south-coast beaches and long lunches.
Book water-based trips through operators who publish their May schedules, and leave the swimming expectations modest until the sea warms through June.
