↓ Falling The tide is falling. 2 h 21 min to low tide at 11:33 am.

Tide coefficient 58 for the 4:40 am high tide and 49 for the 2:47 pm high tide. Low coefficient. The water rises and falls 1.5 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?

2026 extremes: the highest tide of the year is on July 13 (2.3 ft) and the lowest, on February 1 (-0.9 ft).

Mixed: two high and two low tides a day, but of quite different heights.

Heights above MLWS. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLWS

Tide coefficient and range in October

The biggest tides of the month came from October 24 to 26 (coefficient 101, 2.1 ft range). The smallest, on October 2 (coefficient 20, 1.2 ft).

Where this tide comes from

B · Nearby station

Praia da Ferrugem has no station of its own, so we use the tide at Imbituba (TICON-4), 11 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.

One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.8 ft. Before heading out, expect waves of up to 4.8 ft.

Wind on the coast and offshore

On the coast 3 mph ESE · gusts 10
Offshore (9.5 mi NE)Offshore 6 mph SSE · gusts 7

Onshore wind. The coast faces southeast and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.

Today’s surf at a glance

The best window, 5:00 am to 9:00 am, has glassy water, though with a short-period swell. 3:00 pm to 6:57 pm can also work, with glassy water, though with a short-period swell.

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, 10:30 am to 12:40 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 1:50 pm to 3:20 pm, with slack water at high tide, light wind, weak current and the sun high. Also good from 6:30 am to 8:20 am, with 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
  • 1:48–3:48 am Major · the moon passes overhead · high activity
  • 2:21–4:21 pm Major · the moon passes underfoot · high activity
  • 7:26–8:26 am Minor · moonset · medium activity
  • 10:16–11:16 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

Deepens quickly

The bottom deepens quickly: 33 ft of water 1,000 ft from shore.

From the shoreline out to sea, heading southeast.

How far from shore

  • 16 ft deep470 ft
  • 33 ft deep1,000 ft
  • 66 ft deep0.5 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 11 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 1,000 ft and 66 ft at 0.5 mi 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.
