Tides in San Remo
Today's high and low tides
- ▲ High tide 3:49 am 10.3 ft · coef. 86
- ▼ Low tide 9:32 am 3.1 ft
- ▲ Next high tide 3:40 pm 8.7 ft · coef. 89
- ▼ Low tide 9:35 pm 0.5 ft
↑ Rising The tide is rising. 4 h 53 min to high tide at 3:40 pm.
Tide coefficient 86 for the 3:49 am high tide and 89 for the 3:40 pm high tide. Average coefficient. The water rises and falls 9.8 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 May 20 (10.9 ft) and the lowest, on November 28 (0.3 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 come from October 30 to 31 (coefficient 93, 10.2 ft range). The smallest, from October 23 to 24 (coefficient 46, 4.6 ft).

Where this tide comes from
San Remo has no station of its own, so we use the tide at Western Port Stony Point (TICON-4), 13 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 San Remo
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.5 ft
- Significant7.1 ft
- Highest expectedHighest14 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 14 ft. Before heading out, expect waves of up to 14 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 build over the next few days. The biggest waves arrive on Wednesday 4: 9.2 ft with a period of 8 s, from the west-southwest (rough).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 61.4 °F by Wednesday 4.
Water warmer than normal for late October (+1.4 °F).

Surf in San Remo today
Surf today
Fair- 4.7–7.2 ft surf at the shore, a good size with some punch
- Big surf (7.2 ft): for experienced surfers
- 6.4 ft swell at 9 s from the southwest, a bit short
- Light onshore wind (7 mph): a bit of chop
- Falling tide (low tide at 9:35 pm)
Big surf: for experienced surfers only. If in doubt, stay on the beach.
- Light: First light 5:46 am · sunrise 6:14 am · sunset 7:51 pm · last light 8:19 pm
- Tide: high 3:49 am (10.3 ft), low 9:32 am (3.1 ft), high 3:40 pm (8.7 ft) and low 9:35 pm (0.5 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 60.3 °F: a 4/3 fullsuit.
- Energy: 639 kJ · High power
Today’s surf at a glance
The best window, 5:00 pm to 8:00 pm, has a good size, though with big surf. 6:00 am to 10:00 am can also work, with a good size, though with onshore wind.
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 San Remo today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (3:40 pm): little current from 3:10 pm to 4:00 pm
- 6.5 ft swell at 9 s from the southwest: strong surge on the bottom
- Light onshore wind (11 mph)
- 0.2 mph current toward the north-northeast, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 3:49 am (3:30–4:10 am), low tide 9:32 am (9:10–10:00 am), high tide 3:40 pm (3:10–4:00 pm) and low tide 9:35 pm (9:20–9:50 pm)
- Likely visibility: poor. Swell (up to 6.6 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 60.3 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 8:19 pm. Waning gibbous (89%), rising at 11:51 pm: a bright night.
Your diving day at a glance
The best window, 2:30 pm to 4:20 pm, combines slack water at high tide, light wind, weak current and the sun high, though with a big swell. Also worth a look from 8:50 am to 10:50 am, with slack water at low tide, light wind and weak current, though with a big 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.

Moon phase and position
Today the moon is 226,459 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:18–4:18 am Major · the moon passes overhead · high activity
- 2:50–4:50 pm Major · the moon passes underfoot · high activity
- 7:22–8:22 am Minor · moonset · medium activity
- 11:21 pm–12:21 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.

- 16 ft deep1.6 mi
- 33 ft deep1.9 mi
- 66 ft deep2.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 1.6 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 near shore: you only reach 33 ft at 1.9 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). The profile is turned slightly from the coast so it does not run into an island or a headland.
