↑ Rising The tide is rising. 5 h 21 min to high tide at 7:53 am.
Tide coefficient 90 for the 7:53 am high tide and 86 for the 8:19 pm high tide. Spring tides. The water rises and falls 27.4 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 21 (32.6 ft) and the lowest, on March 20 (1.3 ft).
Semidiurnal: two high and two low tides a day, of similar height.
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 26 to 28 (coefficient 97, 29.4 ft range). The smallest, from October 19 to 20 (coefficient 30, 9.5 ft).

Where this tide comes from
Jersey Marine has no station of its own, so we use the tide at Mumbles (TICON-4), 6.5 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.

The sea at Jersey Marine
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.9 ft
- Significant3.8 ft
- Highest expectedHighest7.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.6 ft. Before heading out, expect waves of up to 7.6 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces southwest 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 ease over the next few days. The biggest waves arrive on Thursday 29: 4.1 ft with a period of 9 s, from the west-southwest (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 56.1 °F by Wednesday 4.

Diving in Jersey Marine today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (1:55 pm): little current from 1:30 pm to 2:30 pm
- 2.4 ft swell at 8 s from the west-southwest: some surge on the bottom
- Light cross-shore wind (8 mph)

- Sun high: more light underwater
- Slack water today: low tide 1:34 am (1:10–2:00 am), high tide 7:53 am (7:30–8:20 am), low tide 1:55 pm (1:30–2:30 pm) and high tide 8:19 pm (8:00–8:40 pm)
- Likely visibility: poor. Swell (up to 6.4 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 57.7 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:29 pm. Waning gibbous (85%), rising at 6:37 pm: a bright night.
Your diving day at a glance
The best window, 1:00 pm to 2:30 pm, combines slack water at low tide, light wind, weak current and the sun high. Also worth a look from 7:10 am to 8:30 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.

The moon in Jersey Marine
Moon phase and position
Today the moon is 226,641 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:41–3:41 am Major · the moon passes overhead · high activity
- 2:14–4:14 pm Major · the moon passes underfoot · high activity
- 11:20 am–12:20 pm Minor · moonset · medium activity
- 6:07–7:07 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.6 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
