Seogwipo tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Asia/Seoul local. Folk tradition, not a scientific forecast.

Next spring tide on Tue 05 May (range 2.0m). Next neap on Sat 09 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Seogwipo is on the south coast of Jeju Island, sheltered from the prevailing north wind by Hallasan volcano (1950 m), and benefits from the warm subtropical current that flows along the southern coast. The city has a subtropical climate — the warmest in Korea — and the marine environment reflects this: hawksbill turtles, subtropical reef fish, and warm water (22 to 26°C in summer) that makes diving and snorkelling accessible without a thick wetsuit. Tidal range is semidiurnal with a mean spring range of about 1.2 metres. Jeongbang Waterfall is one of the world's few waterfalls that falls directly into the sea — the 23-metre cascade of the Jeongbang Stream drops off a basalt cliff into the Pacific Ocean. The viewing platform at the base of the cliff (accessed by stairs from the waterfall entrance above) gives a direct view of the falls entering the sea at high tide. At low water, the basalt rock shelf at the base is accessible and the rock pool zone is rich. The waterfall is stronger in summer monsoon (June through August). The fishing village of Cheonjiyeon Waterfall Park hosts Seogwipo's second waterfall — Cheonjiyeon (23 m) falls into a pool before reaching the sea; the access path through subtropical forest is notable for the Taiwanese firefly (Luciola hydrophila) population that is visible at dusk from May through June. The firefly viewing is seasonally restricted. Scuba diving from Seogwipo is the best in South Korea. The 30-40 minute boat trips to Munseom, Seopseom, and Beomseom islets produce consistent encounters with hawksbill and loggerhead sea turtles at most sites — the turtles are habituated to divers. The warm subtropical current brings visibility to 15 to 25 metres on the best days. Several full-service dive shops operate in Seogwipo's harbour area. The annual Seogwipo Fire Festival (in February) and the Haenyeo Culture Festival reflect the town's deep connection to the sea. The haenyeo diver demonstrations at the waterfront market are the most accessible public version of the diving tradition. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge. For Korean tide data, consult KHOA at khoa.go.kr.
