Where this tide comes from

B · Nearby station

Porto do Mangue has no station of its own, so we use the tide at Termisa (Areia Branca, TICON-4), 25 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.

How we calculate the tide

Sea and waves

The sea at Porto do Mangue

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · moderate breeze, Beaufort 4
Waves 3.2 ft · 6.4 s from the east-northeast (61°)
Swell 2.0 ft · 3.9 s from the east-northeast
Current 0.4 mph toward the WNW

The waves you may find

  • Most commonMost common1.6 ft
  • Significant3.2 ft
  • Highest expectedHighest6.6 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.6 ft. Before heading out, expect waves of up to 6.6 ft.

Wind on the coast and offshore

On the coast 8 mph ESE · gusts 14
Offshore (5.2 mi NNE)Offshore 16 mph ESE · gusts 23

Cross-shore wind. The coast faces north and the wind blows along the shore: drift and current run parallel to the beach.

Water warmer than normal for late October (+2.1 °F).

Today’s surf at a glance

The best window, 10:00 am to 12:00 pm, has a good size, though with wind swell. 8:00 am to 9:00 am can also work, though with cross-shore 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.

Your diving day at a glance

The best window, 11:20 am to 1:30 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 5:40 am to 7:10 am, with slack water at high 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
  • 12:59–2:59 am Major · the moon passes overhead · high activity

  • 7:33–8:33 am Minor · moonset · medium activity
  • 8:29–9:29 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

Drops off fast

The bottom drops off fast: the water is 33 ft deep just 50 ft from shore.

From the shoreline (1.6 mi from Porto do Mangue) out to sea, heading north.

How far from shore

  • 16 ft deep30 ft
  • 33 ft deep50 ft
  • 66 ft deep100 ft
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 108 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 50 ft and 66 ft at 100 ft from shore.

Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).

Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
