Where this tide comes from
Barreiro has no station of its own, so we use the tide at Cascais (TICON-4), 19 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The sea at Barreiro
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.7 ft
- Significant5.4 ft
- Highest expectedHighest11 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 11 ft. Before heading out, expect waves of up to 11 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northwest and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Thursday 29: 5.7 ft with a period of 12 s, from the west-northwest (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.
Water colder than normal for late October (−1.9 °F).

Your diving day at a glance
The best window, 3:30 pm to 5:30 pm, combines slack water at high tide, light wind and weak current, though with some swell. Also worth a look from 9:50 am to 10:40 am, with slack water at low tide, light wind, weak current and the sun high, though with some swell.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,641 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:03–4:03 am Major · the moon passes overhead · high activity
- 2:36–4:36 pm Major · the moon passes underfoot · high activity
- 10:32–11:32 am Minor · moonset · medium activity
- 7:39–8:39 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

Water depth
Shallow, gradualShallow, gradual bottom: you need to go 2.4 mi out for 33 ft of water.
From the shoreline (0.25 mi from Barreiro) out to sea, heading northwest.
How far from shore
- 16 ft deep1.8 mi
- 33 ft deep2.4 mi
- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 1.8 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow near shore: you only reach 33 ft at 2.4 mi. For dives deeper than 33 ft, go by boat.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
