What's the weather like in the Algarve in March?
One week you're eating lunch outdoors in a T-shirt, watching early wildflowers open along the clifftops. The next, an Atlantic front rolls in and you're reminded that winter hasn't quite let go. March in the Algarve is a gamble: the odds favour spring, but the house still wins a few rounds.
When the sun's out — and it's out more often than not — the days feel genuinely warm by midday. Orange trees are flowering in the old towns, the countryside is still green from winter rain, and the coast has that sharp early-spring light that makes everything look clean. The beaches are empty, the hiking is superb, and you'll pay a fraction of summer prices for everything.
Temperature
Mornings are jacket weather, no question. Step outside at 8am and you'll feel it, especially inland or on the west coast. But the shift happens fast: by 11am on a clear day, the south coast feels properly warm, particularly in sheltered spots. A terrace in Tavira's old town or the streets of Lagos can feel warmer than the numbers suggest when you're out of the breeze and in direct sun.
The volatility is the thing. A string of 20°C afternoons can be followed by a day that barely cracks 14°C with low cloud and wind. The west coast around Sagres runs cooler and more exposed, while inland valleys can be surprisingly warm during the day and cold at night.
Sunshine and rainfall
The spring sun is stronger than most visitors expect. On clear days, it's easy to sit outside for a few hours and end up pink. Don't skip the sunscreen, even though it doesn't feel like summer.
March still belongs to the rainy season, but only just. When rain comes, it follows the Atlantic pattern: a front moves through, dumps rain for a few hours, and clears. All-day washouts are rare. The second half of March is typically drier than the first, and dry stretches of four or five days are common. You'll want a waterproof layer in your bag, but you probably won't use it often.
Sea temperature and swimming
The sea is at its coldest. This is wading-in-and-gasping territory, not leisurely swimming. A quick dip on a warm afternoon at a sheltered south coast beach like Praia da Marinha or Praia da Luz is doable if you're the type, but you won't linger. Hotels with heated pools are a better bet for actual swimming.
The west coast is where March beaches earn their reputation, though not for swimming. Praia do Amado and Praia da Bordeira still get consistent swells, and the surf community is out in force, all in wetsuits. On the south coast, the calmer water means boat tours and kayaking are starting up along the Ponta da Piedade coastline, weather permitting.
Wind and conditions
Atlantic fronts are still a factor in March, though less frequent than winter. Expect one or two to pass through over a fortnight, each bringing a day of wind and rain before clearing. Between fronts, conditions are often calm and still.
The west coast takes the weather harder. When a front arrives, Sagres and the Costa Vicentina can feel properly windy while the south coast barely notices. On calm days, the eastern Algarve around Tavira and Olhão is often still enough to eat lunch outside without a jacket.
What to pack for March in the Algarve
- Layers: T-shirts, a fleece or light jumper, and a waterproof jacket
- Sunscreen (SPF 30+) and sunglasses — the spring sun is deceptively strong
- Sturdy walking shoes for cliff trails and countryside paths (some trails are muddy after rain)
- A warm layer for evenings — it cools down quickly after sunset
- Swimwear only if your hotel has a heated pool or you're a cold-water swimmer
- Binoculars if you're planning to visit the Ria Formosa or any of the coastal reserves
Events and seasonal highlights
The wildflower season is building through March, with early blooms covering the clifftops between Carvoeiro and Marinha. The real peak comes in April, but March offers a preview without the Easter crowds. The Seven Hanging Valleys trail is already looking good, and the inland countryside is at its greenest.
Orange blossom scents the air in the old towns of Lagos, Silves, and Tavira. Walk through any neighbourhood with citrus trees and you'll catch it. This is also a strong month for birdwatching: spring migration is beginning, and the Ria Formosa Natural Park hosts an overlap of overwintering species and early arrivals.
Why visit the Algarve in March?
March suits visitors who don't mind a bit of unpredictability in exchange for low prices and empty spaces. Accommodation is still at off-season rates, golf courses have available tee times, and the hiking is excellent with green landscapes and comfortable temperatures. The wildflowers are starting, the days are long enough for full afternoons outdoors, and the Algarve feels like it belongs to the people who live here rather than the people who visit.
The honest trade-off: March is a gamble. You might get a week of sunshine and 20°C afternoons, or you might catch a string of Atlantic fronts that bring grey skies and rain. The sea is too cold for swimming, some beach restaurants and bars are still closed, and evenings require warm layers. If you want guaranteed sun, wait for May or June. If you're happy to take what comes and pay less for it, March can be excellent.
Frequently asked questions
Is March a good time to visit the Algarve?
It depends on your expectations. For hiking, golf, cycling, and exploring without crowds, March is very good. For beach holidays and swimming, it's too early. Prices are low and the weather is usually pleasant, but be prepared for occasional rainy days.
Can I swim in the Algarve in March?
The sea is around 16°C, which is too cold for most people. You'll see surfers in wetsuits and the occasional quick dipper on warm afternoons, but comfortable swimming is still a couple of months away. Hotels with heated pools are the practical option.
Does it rain much in March?
Expect rain on roughly six days, usually as short showers rather than all-day downpours. The second half of March tends to be drier. Rain rarely ruins a full day, and dry stretches of several days are common.
Is March warm enough for the beach?
On sunny days, sheltered south coast beaches are pleasant for sunbathing from late morning. The air temperature reaches the high teens on good days, and spots with cliff shelter feel warmer. The sea is cold, so this is a sunbathe-and-walk month rather than a swimming month.
When do wildflowers start in the Algarve?
The first blooms appear in February, but March sees the clifftop displays building noticeably, particularly along the coast between Carvoeiro and Marinha. The full peak comes in April. March offers quieter viewing without the Easter crowds.
How does March compare to April for visiting?
April is more reliably warm, has better wildflower displays, and the days are longer. March is cheaper, quieter, and still enjoyable, but the weather is less predictable. If guaranteed good weather matters, April is the safer choice. If budget and solitude matter more, March delivers.
Is March busy with tourists?
No. March is still off-season for most visitors. Beaches are empty, restaurants take walk-ins, and popular trails are uncrowded. You'll share the Algarve with golfers, hikers, and a few early-season visitors rather than the summer crowds.
What should I pack for the Algarve in March?
Layers are essential: T-shirts for warm afternoons, a fleece for mornings and evenings, and a waterproof jacket for the occasional shower. Bring sunscreen, as the spring sun is stronger than expected. Sturdy shoes are useful for trails that may be muddy from winter rain.
