Today's high and low tides

  • ▼ Low tide 9:55 pm 0.1 ft

↑ Rising The tide is rising. 4 h 7 min to high tide at 5:48 am.

Tide coefficient 67 for the 5:48 am high tide and 58 for the 5:18 pm high tide. Low coefficient. The water rises and falls 3.6 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 March 2 (4.7 ft) and the lowest, on September 25 (-1.0 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 25 (coefficient 106, 4.9 ft range). The smallest, on October 18 (coefficient 20, 1.6 ft).

Where this tide comes from

B · Nearby station

Ilha Comprida has no station of its own, so we use the tide at Cananéia (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

One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.1 ft. Before heading out, expect waves of up to 6.1 ft.

Today’s surf at a glance

The best window, 5:01 am to 9:00 am, has glassy water, though with a short-period swell. 6:00 pm to 6:47 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, 10:10 am to 1:10 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 5:20 am to 6:20 am, with slack water at high tide, light wind and weak current. Also good from 4:40 pm to 5:50 pm, 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.

Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

  • 7:31–8:31 am Minor · moonset · 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

Shallow, gradual

Shallow, gradual bottom: you need to go 1.3 mi out for 33 ft of water. Right off the beach it already drops to about 14 ft.

From the shoreline (1,200 ft from Ilha Comprida) out to sea, heading southeast.

How far from shore

  • 16 ft deep650 ft
  • 33 ft deep1.3 mi
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 14 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. Shallow near shore: you only reach 33 ft at 1.3 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).

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