Semidiurnal: two high and two low tides a day, of similar height.
Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

Where this tide comes from
Samouco has no station of its own, so we use the tide at Cascais (TICON-4), 22 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 Samouco
Sea stateSea state: slight
The waves you may find
- Most commonMost common2.0 ft
- Significant4.1 ft
- Highest expectedHighest8.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.0 ft. Before heading out, expect waves of up to 8.0 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 Wednesday 28: 5.2 ft with a period of 13 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 cools over the next few days: about 63.5 °F by Tuesday 3.

- Likely visibility: fair. Swell (up to 5.1 ft at 11 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 64.2 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:08 pm. Waning gibbous (92%), rising at 7:07 pm: a bright night.
Your diving day at a glance
The best window, 8:50 am to 10:20 am, combines slack water at low tide, light wind, weak current and the sun high, though with a big swell. Also worth a look from 2:50 pm to 4:20 pm, with slack water at high tide, light wind and weak current, though with a big 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.

The moon in Samouco
Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:59–2:59 am Major · the moon passes overhead · high activity
- 1:31–3:31 pm Major · the moon passes underfoot · high activity
- 9:21–10:21 am Minor · moonset · medium activity
- 6:37–7:37 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.1 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
