Where this tide comes from
Porto Judeu has no station of its own, so we use the tide at Angra do Heroísmo (TICON-4), 6.5 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 Judeu
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.2 ft
- Significant6.5 ft
- Highest expectedHighest13 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 13 ft. Before heading out, expect waves of up to 13 ft.
Wind on the coast and offshore
Offshore wind. The coast faces south and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Saturday 31: 8.5 ft with a period of 9 s, from the north-northeast (rough).
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 Judeu today
Surf today
Poor- 2.9–4.4 ft surf at the shore, a good size with some punch
- 2.4 ft swell at 7 s from the north, short: weak, messy waves; this coast faces away from it
- 4.3 ft wind swell at 4 s: messy waves
- Light onshore wind (11 mph): a bit of chop
- Falling tide (high tide at 2:34 pm)
- Light: First light 6:44 am · sunrise 7:11 am · sunset 5:53 pm · last light 6:20 pm
- Tide: high 2:15 am (5.2 ft), low 8:27 am (0.8 ft), high 2:34 pm (4.9 ft) and low 8:45 pm (0.9 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 69.6 °F: a springsuit or a 2 mm fullsuit.
- Energy: 108 kJ · Medium power
Today’s surf at a glance
The best window, 7:00 am to 11:00 am, has a good size, though with a short-period swell, wind swell and onshore wind. 12:00 pm to 4:00 pm can also work, with a good size, though with a short-period swell, wind swell and 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 Porto Judeu today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (8:27 am): little current from 8:10 am to 8:50 am

- Likely visibility: poor. Swell (up to 7.6 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 69.6 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:20 pm. Waning gibbous (92%), rising at 7:23 pm: a bright night.
Your diving day at a glance
The best window, 7:10 am to 9:20 am, combines slack water at low tide and light wind, though with waves and current. Also worth a look from 2:10 pm to 3:30 pm, with slack water at high tide, weak current and the sun high, though with waves 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.
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 226,444 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:15–3:15 am Major · the moon passes overhead · high activity

- 9:36–10:36 am Minor · moonset · medium activity
- 6:53–7:53 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.
