Tide coefficient 95 for the 6:52 am high tide and 89 for the 6:59 pm high tide. Spring tides. The water rises and falls 5.1 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 December 25 (5.8 ft) and the lowest, on August 13 (0.0 ft).

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

Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

Tide coefficient and range in October

The biggest tides of the month came from October 10 to 12 (coefficient 109, 5.0 ft range). The smallest, from October 4 to 5 (coefficient 20, 2.1 ft).

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

The best window, 2:00 pm to 5:46 pm, has glassy water, though with barely any waves.

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.

Your diving day at a glance

The best window, 11:30 am to 1:00 pm, combines slack water at low tide, little swell, light wind and the sun high, though with current. Also worth a look from 5:40 am to 7:20 am, with slack water at high tide, little swell and light wind, though with 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.

Solunar periods

Today's activity: medium
  • 12:42–2:42 am Major · the moon passes overhead · high activity
  • 1:15–3:15 pm Major · the moon passes underfoot · high activity
  • 7:31–8:31 am Minor · moonset · medium activity
  • 7:58–8:58 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 40 ft from shore. It reaches 164 ft at 240 ft.

From the shoreline (0.7 mi from Bitung) out to sea, heading south.

How far from shore

  • 16 ft deep20 ft
  • 33 ft deep40 ft
  • 66 ft deep80 ft
  • 164 ft deep240 ft

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 189 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 40 ft and 66 ft at 80 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.
