↓ Falling The tide is falling. 3 h 23 min to low tide at 11:50 am.
Tide coefficient 94 for the 4:13 am high tide and 89 for the 4:12 pm high tide. Spring tides. The water rises and falls 3.4 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 December 25 (2.5 ft) and the lowest, on December 24 (-1.6 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. mean sea level
Tide coefficient and range in October
The biggest tides of the month came from October 12 to 13 (coefficient 110, 3.2 ft range). The smallest, on October 20 (coefficient 20, 1.5 ft).

Where this tide comes from
Marion Bay has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 2.3 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.
Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.
The sea at Marion Bay
Sea stateSea state: slight
The waves you may find
- Most commonMost common2.0 ft
- Significant3.9 ft
- Highest expectedHighest7.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.8 ft. Before heading out, expect waves of up to 7.8 ft.
Wind on the coast and offshore
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.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Wednesday 4: 5.9 ft with a period of 8 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 is steady these days, with no sudden changes.

Surf in Marion Bay today
Surf today
Good- 2.7–4.2 ft surf at the shore, a good size with some punch
- 3.9 ft swell at 10 s from the southwest, a bit short
- Light offshore wind (8 mph): it holds up and grooms the waves
- Rising tide (high tide at 4:12 pm)
- Light: First light 5:56 am · sunrise 6:23 am · sunset 7:49 pm · last light 8:16 pm
- Tide: high 4:13 am (2.3 ft), low 11:50 am (-1.1 ft), high 4:12 pm (-0.5 ft) and low 9:03 pm (-1.2 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 63.1 °F–64.2 °F: a 3/2 fullsuit.
- Energy: 263 kJ · Medium power
Today’s surf at a glance
The best window, 2:00 pm to 6:00 pm, has a good size and light offshore wind. 10:00 am to 1:00 pm also works, with a good size.
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.
Diving in Marion Bay today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (4:12 pm): little current from 3:40 pm to 4:50 pm
- 3.9 ft swell at 10 s from the southwest: strong surge on the bottom
- Light offshore wind (7 mph)
- 0.2 mph current toward the west-northwest, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 4:13 am (3:58–4:30 am), low tide 11:50 am (11:30 am–12:20 pm), high tide 4:12 pm (3:40–4:50 pm) and low tide 9:03 pm (8:30–9:30 pm)
- Likely visibility: fair. Swell (up to 4.3 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 63.1–64.2 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 8:16 pm. Waning gibbous (89%), rising at 11:44 pm: a bright night.
Your diving day at a glance
The best window, 2:40 pm to 4:30 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 11:20 am to 12:20 pm, with slack water at low 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 226,463 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:23–4:23 am Major · the moon passes overhead · high activity
- 2:55–4:55 pm Major · the moon passes underfoot · high activity
- 7:39–8:39 am Minor · moonset · medium activity
- 11:14 pm–12:14 am 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 1.1 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 near shore: you only reach 33 ft at 1.7 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
