- ▼ Low tide 10:33 pm 0.6 ft
↓ Falling The tide is falling. 2 h 58 min to low tide at 11:31 am.
Tide coefficient 90 for the 3:55 am high tide and 84 for the 6:50 pm high tide. Spring tides. The water rises and falls 1.0 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 26 (1.1 ft) and the lowest, on December 25 (-0.1 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 26 to 28 (coefficient 99, 1.0 ft range). The smallest, on October 19 (coefficient 30, 0.6 ft).

Where this tide comes from
Tides from the Donghae Port station (KHOA), 0.9 mi from Tonghae. Times and heights are its predictions.

The sea at Tonghae
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.6 ft
- Highest expectedHighest3.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.4 ft. Before heading out, expect waves of up to 3.4 ft.
Wind on the coast and offshore
Offshore wind. The coast faces northeast and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 4: 3.2 ft with a period of 6 s, from the north-northeast (slight).
Water temperature
Water temperature →The satellite measured 5.2 °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 63.3 °F by Wednesday 4.
Water about normal for late October.

Surf in Tonghae today
Surf today
Poor- 1.4–2.1 ft surf at the shore, a fun size for most surfers
- 1.8 ft swell at 5 s from the north-northeast, short: weak, messy waves
- Light offshore wind (7 mph): it holds up and grooms the waves
- First or last light of the day
- Falling tide (low tide at 11:31 am)
- Light: First light 6:18 am · sunrise 6:45 am · sunset 5:29 pm · last light 5:56 pm
- Tide: high 3:55 am (1.0 ft), low 11:31 am (-0.0 ft), high 6:50 pm (0.7 ft) and low 10:33 pm (0.6 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 64.8 °F: a 3/2 fullsuit.
- Energy: 14 kJ · Low power
Today’s surf at a glance
The best window, 6:18 am to 10:00 am, has light offshore wind, though with a short-period swell. 12:00 pm to 4:00 pm can also work, with light offshore wind, though with small waves and a short-period swell.
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.

Your diving day at a glance
The best window, 10:50 am to 12:20 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high.
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 Tonghae
Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:26–3:26 am Major · the moon passes overhead · high activity
- 1:58–3:58 pm Major · the moon passes underfoot · high activity
- 9:48–10:48 am Minor · moonset · medium activity
- 7:06–8:06 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.3 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. Shore diving works here: 33 ft at 0.45 mi and 66 ft at 0.9 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
