The sea at Sansha
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.8 ft
- Significant7.6 ft
- Highest expectedHighest16 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 16 ft. Before heading out, expect waves of up to 16 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-onshore wind. The coast faces northeast 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 Thursday 29: 7.8 ft with a period of 8 s, from the east-northeast (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.
Water warmer than normal for late October (+3.2 °F).

Surf in Sansha today
Surf today
Poor- 4.5–7.0 ft surf at the shore, a good size with some punch
- 6.1 ft swell at 7 s from the east-northeast, short: weak, messy waves
- Moderate onshore wind (17 mph): choppy, blown-out waves
- Light: First light 6:05 am · sunrise 6:27 am · sunset 6:01 pm · last light 6:23 pm
- Tide: We don’t have a reliable tide to show here.
- Water at 84.4 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 403 kJ · Medium power
Today’s surf at a glance
The best window, 12:00 pm to 4:00 pm, has a good size, though with a short-period swell and onshore wind. 6:05 am to 10:00 am can also work, with a good size, though with big surf, a short-period swell and 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 Sansha today
Diving and snorkeling today
Likely visibility: poor- 6.1 ft swell at 7 s from the east-northeast: strong surge on the bottom
- Moderate onshore wind (17 mph)
- 0.6 mph current toward the west-southwest (model)
- Sun high: more light underwater
Not a day for shore diving: swell, wind, current or storms during the best window. If you go, go with a dive shop and only if they give the OK.
- Slack water today: none; the tide doesn't count here
- Likely visibility: poor. Swell (up to 6.6 ft at 8 s), rain (0.27 in) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 84.4 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:23 pm. Waning gibbous (88%), rising at 8:47 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 2:30 pm, lines up with the sun high, though with a big swell, moderate wind and current. Also worth a look from 6:30 am to 8:30 am, with weak current, though with a big swell and fresh wind.
We don't have a reliable tide for Sansha, so slack water doesn't count in the rating.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Sansha
Moon phase and position
Today the moon is 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:36–3:36 am Major · the moon passes overhead · high activity
- 2:08–4:08 pm Major · the moon passes underfoot · high activity
- 8:59–9:59 am Minor · moonset · medium activity
- 8:17–9:17 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.

Water depth
Shallow, gradualShallow, gradual bottom: you need to go 2.2 mi out for 33 ft of water. It reaches 164 ft at 3 mi.
From the shoreline (1,000 ft from Sansha) out to sea, heading northeast.
How far from shore
- 16 ft deep2.1 mi
- 33 ft deep2.2 mi
- 66 ft deep2.5 mi
- 164 ft deep3 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.1 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 2.2 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). Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
