Is March Right for You?
Weigh the advantages and considerations before booking
Advantages
- + March hands you the Atlantic coast's best-kept secret: winter swells have quieted but summer crowds have not yet landed, so you will split Praia do Guincho with maybe a dozen surfers instead of the August chaos. Worth it. The lineup stays friendly. You catch more waves. You park free.
- + Hotel rates along Avenida Dom Carlos I fall to shoulder-season levels while the town's well-known restaurants, like 40-year-old Mar do Inferno at Boca do Inferno, still run their full winter menus starring percebes (goose barnacles) at peak freshness. Eat them now. Prices dip. Flavors spike.
- + The coastal walking trail from Cascais to Estoril turns pleasant in March's mild temperatures. You will want to walk the full 2.5 km (1.6 miles) instead of collapsing into an Uber like summer visitors do. Breathe easy. No sweat. Pure Atlantic air.
- + Local life snaps back to normal after winter. Fishermen mend nets at Praia dos Pescadores, grandmothers reclaim their regular benches in Marechal Garden, and the Tuesday-Saturday market at Rua Padre Moisés da Silva bustles with residents rather than tourists. Watch. Listen. Learn rhythms.
Considerations
- − Ocean temperatures hover around 15°C (59°F); locals call this 'frio de cortar' (cutting cold), so beach days demand the dedication of a polar bear club member. Bring neoprene. Or courage. Or both.
- − March still hurls those famous Atlantic storms that roll in fast and hard; Boca do Inferno's dramatic waves might be Instagram-worthy but they will also soak you to the bone if you edge too close. Keep distance. Respect power.
- − Many seasonal businesses, the beach bars at Praia da Rainha, the outdoor terraces along Rua Frederico Aroua, remain shuttered until Easter, leaving the town feeling half-asleep some evenings. Plan dinners early.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
March is when locals use the indoor heated pool at Piscina Oceânica Alberto Romano. Tourists do not know it exists, costs a fraction of hotel spa pools. Swim cheap.
The Tuesday-Saturday market on Rua Padre Moisés da Silva runs 7am-2pm but vendors start packing at 1pm. Arrive by 10am for the best selection of winter produce and fresh fish that did not sell over the weekend. Move fast.
Restaurant week happens mid-March; established spots like Hemingway (running 35 years) offer fixed menus that let you taste their classics without the usual splurge. Book tables.
March storms punch shallow bowls into Praia da Rainha. These fleeting tide pools turn into living aquariums. Kids crouch, stare, shriek with delight. Instagrammers never see it. They only come in summer.
Avoid These Mistakes
March is not spring here. Portuguese March clings to winter. Pack for San Francisco in April. Forget Barcelona vibes. Bring layers.
Ocean-view rooms promise storm romance. March gales hit 45 mph (72 km/h). Windows jitter. Sleep flees. Interior rooms stay quiet.
White sneakers die here. Coastal trails bleed red clay. Stains lock in forever. Guides spot the footwear from kilometers away. Wear dark shoes.
Low season lulls travelers. March weekends fool Lisbon locals. They drive to the coast. Tables fill fast. Book ahead. Sunday lunch disappears.
