Where this tide comes from
Porto da Cruz has no station of its own, so we use the tide at Funchal (TICON-4), 9.7 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 Porto da Cruz
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.3 ft
- Significant2.7 ft
- Highest expectedHighest5.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.3 ft. Before heading out, expect waves of up to 5.3 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
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 Sunday 1: 3.2 ft with a period of 7 s, from the southwest (slight).
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.

Surf in Porto da Cruz today
Surf today
Poor- 1.1–1.8 ft surf at the shore, small: good for learning or a longboard
- 2.0 ft swell at 9 s from the west-northwest, a bit short; it hits this coast at an angle
- Almost no wind (2 mph): glassy water
- Falling tide (low tide at 9:31 am)
- Light: First light 6:57 am · sunrise 7:22 am · sunset 6:19 pm · last light 6:45 pm
- Tide: high 3:20 am (8.0 ft), low 9:31 am (1.4 ft), high 3:48 pm (7.4 ft) and low 9:45 pm (1.8 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 73.2 °F: a rash guard or a neoprene top.
- Energy: 55 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 11:00 am, has glassy water. 1:00 pm to 4:00 pm can also work, with light offshore wind, though with small waves.
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 Porto da Cruz today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (3:48 pm): little current from 3:20 pm to 4:10 pm
- 1.4 ft swell at 8 s from the west-northwest: some surge on the bottom
- Light offshore wind (5 mph)
- 0.2 mph current toward the north-northeast, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 3:20 am (3:00–3:40 am), low tide 9:31 am (9:10–10:00 am), high tide 3:48 pm (3:20–4:10 pm) and low tide 9:45 pm (9:20–10:10 pm)
- Likely visibility: fair. Swell (up to 3.5 ft at 11 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 73.2 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:45 pm. Waning gibbous (85%), rising at 9:02 pm: a bright night.
Your diving day at a glance
The best window, 2:50 pm to 4:30 pm, combines slack water at high tide, light wind, weak current and the sun high. Also good from 8:50 am to 10:40 am, with slack water at low tide, light wind and weak current.
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- 2:36–4:36 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.

Water depth
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 340 ft from shore. It reaches 164 ft at 1.2 mi.
From the shoreline (0.8 mi from Porto da Cruz) out to sea, heading northeast.
How far from shore
- 16 ft deep170 ft
- 33 ft deep340 ft
- 66 ft deep0.4 mi
- 164 ft deep1.2 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 32 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 340 ft and 66 ft at 0.4 mi from shore.
Right by the shore the bottom may drop even faster than shown.
