2026 extremes: the highest tide of the year is on June 16 (6.7 ft) and the lowest, on December 25 (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)

The sea at Sanctuary Point
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.2 ft
- Significant4.5 ft
- Highest expectedHighest9.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 9.0 ft. Before heading out, expect waves of up to 9.0 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces south 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.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Friday 30: 5.6 ft with a period of 10 s, from the south-southeast (moderate).

Your diving day at a glance
The best window, 4:50 pm to 6:50 pm, combines slack water at low tide, light wind and weak current, though with some swell. Also worth a look from 9:50 am to 11:40 am, with slack water at high tide, light wind and the sun high, though with some swell and 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.

Moon phase and position
Today the moon is 226,459 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:56–3:56 am Major · the moon passes overhead · high activity
- 2:28–4:28 pm Major · the moon passes underfoot · high activity
- 7:13–8:13 am Minor · moonset · medium activity
- 10:46–11:46 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.
