Where this tide comes from
Songdo Beach has no station of its own, so we use the tide at Busan (KHOA), 1.7 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 Busan (부산, DT_0005), https://www.data.go.kr/data/15145395/fileData.do. Free, no restrictions on use (이용허락범위 제한 없음). Modified by TidePlanet: M2, S2, K1 and O1 from KHOA, the other constituents of those bands inferred from them.
The sea at Songdo Beach
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.3 ft
- Significant0.6 ft
- Highest expectedHighest1.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.2 ft. Before heading out, expect waves of up to 1.2 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces southeast and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 2.0 ft with a period of 5 s, from the southeast (slight).
Water temperature
Water temperature →The satellite measured 4.7 °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 65.1 °F by Wednesday 4.
Water about normal for late October.

Today’s surf at a glance
The best window, 6:16 am to 10:00 am, has glassy water, though with barely any waves.
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, 9:10 am to 10:30 am, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 3:30 pm to 4:50 pm, with slack water at low 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.

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
- 9:40–10:40 am Minor · moonset · medium activity
- 7:15–8:15 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 0.4 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. 33 ft deep 0.45 mi from shore; 66 ft is far out (1.3 mi): for deeper dives, go by boat.
