The water rises and falls 16.6 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 19 (17.3 ft) and the lowest, on December 26 (-0.4 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above chart datum (CD), the zero of that port's nautical charts. 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 (CD)

Where this tide comes from
Sinan has no station of its own, so we use the tide at Sinan (Songgong, KHOA), 6.8 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.
Station data attribution: Korea Hydrographic and Oceanographic Agency (해양수산부 국립해양조사원), harmonic constants of the TideBED reference ports (예측조위(타이드베드) 기준항 조화상수, 2025-08-12), station Sinan (Songgong) (신안송공, SO_0566), https://www.data.go.kr/data/15145395/fileData.do.

The sea at Sinan
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.2 ft
- Highest expectedHighest2.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.6 ft. Before heading out, expect waves of up to 2.6 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces west and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Saturday 31: 1.9 ft with a period of 3 s, from the northwest (slight).
Water temperature
Water temperature →The satellite measured 6.1 °F more 2 days ago than the model gives now: the water is probably warmer than the forecast says.
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 61.5 °F by Wednesday 4.
Water about normal for late October.

Your diving day at a glance
The best window, 8:40 am to 10:10 am, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also worth a look from 3:10 pm to 4:20 pm, with slack water at high tide, little swell and weak current, though with moderate wind.
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.

The moon in Sinan
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:38–3:38 am Major · the moon passes overhead · high activity
- 2:10–4:10 pm Major · the moon passes underfoot · high activity
- 9:51–10:51 am Minor · moonset · medium activity
- 7:28–8:28 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.
