  • ▼ Low tide 10:52 am 0.4 ft
  • ▲ High tide 3:39 pm 2.8 ft · coef. 83

↓ Falling The tide is falling. 5 h 4 min to low tide at 10:57 pm.

Tide coefficient 91 for the 3:48 am high tide and 83 for the 3:39 pm high tide. Spring tides. The water rises and falls 3.7 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 19 (4.2 ft) and the lowest, on August 12 (-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 25 to 26 (coefficient 108, 4.1 ft range). The smallest, on October 18 (coefficient 20, 1.4 ft).

Waves 2.8 ft · 7.4 s from the south-southeast (152°)

One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.6 ft. Before heading out, expect waves of up to 5.6 ft.

Cross-onshore wind. The coast faces southeast and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.

Water warmer than normal for late October (+2.8 °F).

Your diving day at a glance

The best window, 9:30 am to 11:40 am, combines slack water at low tide, light wind, weak current and the sun high. Also good from 3:10 pm to 4:10 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.

Solunar periods

Today's activity: medium
  • 12:22–2:22 am Major · the moon passes overhead · high activity
  • 12:54–2:54 pm Major · the moon passes underfoot · high activity
  • 6:17–7:17 am Minor · moonset · medium activity
  • 8:33–9:33 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.
