Where this tide comes from
São Vicente has no station of its own, so we use the tide at Ponta Delgada (TICON-4), 5.8 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 São Vicente
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.5 ft
- Significant7.0 ft
- Highest expectedHighest14 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 14 ft. Before heading out, expect waves of up to 14 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces northeast and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 7.5 ft with a period of 9 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 69.3 °F by Wednesday 4.

Surf in São Vicente today
Surf today
Poor- 1.9–2.9 ft surf at the shore, a fun size for most surfers
- 4.9 ft swell at 9 s from the west, a bit short; it hits this coast at an angle
- Light onshore wind (8 mph): a bit of chop
- Rising tide (high tide at 3:21 pm)
- Light: First light 6:38 am · sunrise 7:05 am · sunset 5:47 pm · last light 6:14 pm
- Tide: high 2:56 am (5.5 ft), low 9:12 am (1.1 ft), high 3:21 pm (5.1 ft) and low 9:28 pm (1.3 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 70.2 °F: a springsuit or a 2 mm fullsuit.
- Energy: 340 kJ · Medium power
Today’s surf at a glance
The best window, 9:00 am to 1:00 pm, has a good size. 7:00 am to 8:00 am can also work, with a good size, though with onshore wind. 5:00 pm to 6:00 pm can also work, with a good size, though with onshore wind.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.
Diving in São Vicente today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (9:12 am): little current from 8:50 am to 9:40 am
- 4.7 ft swell at 9 s from the west: strong surge on the bottom
- Light onshore wind (9 mph)
- 0.3 mph current toward the southwest, weak (model)

- Likely visibility: poor. Swell (up to 4.9 ft at 9 s) and rain (1.89 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 70.2 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:14 pm. Waning gibbous (85%), rising at 8:21 pm: a bright night.
Your diving day at a glance
The best window, 8:10 am to 9:40 am, combines slack water at low tide, light wind and weak current, though with some swell. Also worth a look from 2:50 pm to 3:30 pm, with slack water at high tide, weak current and the sun high, though with a big swell and moderate wind.
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.

Solunar periods
Today's activity: medium- 2:12–4:12 am Major · the moon passes overhead · high 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. 33 ft of water just 0.25 mi from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
