↓ Falling The tide is falling. 1 h 1 min to low tide at 1:18 pm.
Tide coefficient 52 for the 7:00 am high tide and 47 for the 8:33 pm high tide. Low coefficient. The water rises and falls 11.0 ft between the highest high and the lowest low: an average 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 22 (19.3 ft) and the lowest, on August 10 (-0.3 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)
Tide coefficient and range in October
The biggest tides of the month came from October 23 to 24 (coefficient 103, 17.6 ft range). The smallest, from October 15 to 16 (coefficient 28, 6.7 ft).

Where this tide comes from
Haeju has no station of its own, so we use the tide at Sunwi-do (KHOA), 29 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 Sunwi-do (순위도, NS_0017), https://www.data.go.kr/data/15145395/fileData.do.

The sea at Haeju
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.1 ft
- Significant2.3 ft
- Highest expectedHighest4.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.9 ft. Before heading out, expect waves of up to 4.9 ft.
Wind on the coast and offshore
Onshore wind. The coast faces south and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 2.4 ft with a period of 4 s, from the south-southwest (slight).
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 57.0 °F by Wednesday 4.
Water colder than normal for late October (−3.6 °F).

Your diving day at a glance
The best window, 1:30 pm to 2:30 pm, combines slack water at low tide, little swell, weak current and the sun high, though with moderate wind. Also good from 6:30 am to 8:00 am, with slack water at high tide, little swell, light wind and weak 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 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:40–3:40 am Major · the moon passes overhead · high activity
- 2:12–4:12 pm Major · the moon passes underfoot · high activity
- 10:05–11:05 am Minor · moonset · medium activity
- 7:18–8:18 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.
