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

Where this tide comes from

B · Nearby station

Praia das Pacas has no station of its own, so we use the tide at Imbituba (TICON-4), 31 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.

Sea and waves

The sea at Praia das Pacas

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · light breeze, Beaufort 2
Waves 1.4 ft · 6.4 s from the east-southeast (104°)
Swell 1.3 ft · 5.5 s from the east-southeast
Current 0.2 mph toward the SSE

The waves you may find

  • Most commonMost common0.7 ft
  • Significant1.4 ft
  • Highest expectedHighest3.0 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.0 ft. Before heading out, expect waves of up to 3.0 ft.

Wind on the coast and offshore

On the coast 6 mph NNW · gusts 10

The model doesn't separate offshore wind here: it's the same as on the coast.

Offshore wind. The coast faces southeast and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

Water now69.1 °F

Satellite (2 days ago) 65.8 °F measured 0.5 mi away

The satellite measured 3.2 °F less 2 days ago than the model gives now: the water is probably colder than the forecast says.

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 72.5 °F by Wednesday 4.

Water colder than normal for late October (−2.5 °F).

The best window, 5:00 am to 9:00 am, has glassy water, though with small waves and 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, little swell, light wind, weak current and the sun high. Also good from 1:50 pm to 3:20 pm, with slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 5:20 am to 8:20 am, with slack water at high tide, little swell, 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

  • 7:26–8:26 am Minor · moonset · medium activity
  • 10:15–11:15 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

Gentle slope

The bottom slopes gently: 16 ft deep 0.55 mi from shore and 33 ft at 0.65 mi.

From the shoreline out to sea, heading southeast.

How far from shore

  • 16 ft deep0.55 mi
  • 33 ft deep0.65 mi
  • 66 ft deep2.9 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.55 mi): cast far from the beach and fish the high tide, when there is more water close in.
  • Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
  • Diving. Shallow near shore: you only reach 33 ft at 0.65 mi. For dives deeper than 33 ft, go by boat.

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