Tide coefficient 93 for the 7:36 am high tide and 88 for the 8:01 pm high tide. Spring tides. The water rises and falls 2.9 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 November 26 (3.8 ft) and the lowest, on March 22 (0.1 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 100, 2.8 ft range). The smallest, from October 19 to 20 (coefficient 21, 0.1 ft).

Waves 3.6 ft · 10.7 s from the south (185°)

The waves you may find

  • Most commonMost common1.8 ft

  • Highest expectedHighest7.3 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.3 ft. Before heading out, expect waves of up to 7.3 ft.

Wind on the coast and offshore

On the coast 4 mph WNW · gusts 11
Offshore (6.2 mi SW)Offshore 1 mph WNW · gusts 4

Cross-offshore wind. The coast faces south and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

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

The best window, 6:00 am to 10:00 am, has a good size and glassy water.

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, 12:10 pm to 1:50 pm, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 6:50 am to 8:20 am, with slack water at high tide, light wind and weak current, though with some swell.

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
  • 1:37–3:37 am Major · the moon passes overhead · high activity

  • 8:23–9:23 am Minor · moonset · medium activity
  • 8:55–9:55 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 750 ft from shore.

From the shoreline (2 mi from Teluk Dalam) out to sea, heading south.

How far from shore

  • 16 ft deep480 ft
  • 33 ft deep750 ft
  • 66 ft deep0.45 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 7.5 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
  • Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
  • Diving. Shore diving works here: 33 ft at 750 ft and 66 ft at 0.45 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).
