65m in 3–5m on excellent flat sand — one of the best-holding beach anchorages on the Alentejo coast. The NE orientation gives marginally better Nortada protection than purely W-facing beaches. Depart immediately on any southerly forecast.
About This Anchorage
Praia do Malhão is a long, almost entirely empty Atlantic beach immediately NW of Sines — part of the Costa Vicentina Natural Park (PNSACV). The beach stretches for over 3km and is backed by low dunes and scrub vegetation. The bay's NE-facing aspect provides marginally better protection from the afternoon Nortada than many other Alentejo beaches — the cliffs and headland NW of Sines provide some deflection of the prevailing NW trade wind. The sand holding is outstanding — flat, firm, clean sand throughout. An excellent overnight anchorage in settled summer conditions, with the wild PNSACV landscape and night sky making this one of the most memorable anchorages on the Portuguese Atlantic coast.

Orca Interaction Protocol — Alentejo Coast
This anchorage is within the orca interaction zone (Atlantic Portugal 36°N–38°N). If orcas approach under way: stop engine immediately, lower sails, release wheel and drift passively. Do not attempt to manoeuvre or accelerate. Report all interactions at orcas.pt and on VHF Ch. 16. The Nortada builds strongly by 12:00 — plan morning departures to minimise motoring time in interaction waters.
Setting Your Anchor
Deploy 7:1 scope minimum on the Alentejo coast — Atlantic groundswell can arrive overnight even in settled summer weather and will put significant loading on the rode. If staying overnight, use 10:1 scope for additional security.
Nortada assessment: The afternoon Nortada builds from 10:00–12:00 most summer days. If you are setting your anchor for the night, set it at peak Nortada strength to confirm it holds in the worst daytime conditions you are likely to see.
Atlantic swell assessment: Check the ipma.pt ocean swell (ondas) model before anchoring overnight. A 1m SW groundswell arriving at 03:00 will make many Alentejo anchorages uncomfortable or dangerous — know your departure conditions in advance.
Orca protocol reminder: Do not run your engine unnecessarily when in orca interaction waters. Consider anchoring for the night rather than motoring through peak interaction hours (dawn to mid-morning).

Hazards
- !S/SW/W exposure — any Atlantic swell from S/SW makes the anchorage untenable; Nortada afternoon swell from NW builds quickly
- !No facilities of any kind — fully self-sufficient overnight stay
- !ORCA RISK on passages nearby — engine-off protocol if approached
Skipper's Tips
- →One of the best overnight anchor spots on the Alentejo coast in settled summer conditions — flat sand, no crowds, extraordinary night sky with no light pollution
- →The NE aspect means the Nortada afternoon chop is marginally less severe than on purely W-facing beaches — test conditions before committing to overnight
- →Sines is 5nm N — a short motor to top up provisions, fuel, and water before a remote Malhão overnight
- →Best viewed at sunset: the empty beach, cork oak scrubland and the orange Atlantic light from the cockpit is genuinely stunning
Facilities
Nearest provisions: Sines town centre (5nm)
Best Months & Season
May, June, July, August, September
May–September settled high-pressure windows. One of the most remote and beautiful overnight anchorages on the Portuguese coast when conditions allow. Not a Nortada refuge — the afternoon wind will build regardless.

Sleep Peacefully at Praia do Malhão
The Nortada builds while you sleep — sometimes from nothing at 02:00. On the Alentejo coast, an unexpected afternoon gust or arriving Atlantic swell can set a vessel dragging before the skipper wakes. Safety Anchor Alarm monitors your position through the night and fires an alert the moment you move beyond your set radius — giving you time to act before the beach finds you.
