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/Rangoon local. Folk tradition, not a scientific forecast.

Last spring tide on Tue 19 May (range 3.3m). Next neap on Sat 23 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.

Kawthaung is the southernmost town in Myanmar, occupying a peninsula at the tip of the Tanintharyi Region where the Andaman Sea meets the Strait of Malacca, directly opposite Ranong in Thailand across the Pak Chan River estuary. The two towns are connected by a 15-minute longtail boat crossing; the estuary is 1.5 km wide, the current runs 1 to 2 knots on both ebb and flood, and the crossing is made dozens of times each day by traders, day-trippers with Thai border passes, and travellers completing an overland crossing. The English colonial name Victoria Point appears on older charts and in WWII records of the region. The town has the practical density of a working border port: a covered market where fresh fish, tropical fruit, and border-trade goods from Thailand sit side by side, a waterfront restaurant strip, a cluster of guesthouses, and the logistics of the liveaboard fleet that provisions here before heading north into the Myeik Archipelago. The pagoda on the hilltop above the town is the visual landmark visible from the Thai side of the estuary. Lampi Marine National Park, accessible by longtail or liveaboard from Kawthaung pier, is the most easily reached significant island in the outer Myeik Archipelago: 20 km long, with mangrove-lined coasts accessible by boat, coral reefs on the western edge, freshwater streams and waterfalls in the interior, and essentially no tourist infrastructure beyond the park office. Day trips from Kawthaung are possible in calm conditions; overnight requires a park permit. The park protects a section of the outer archipelago where Moken sea nomads have traditional seasonal camps, and the terrestrial forest holds hornbills, kingfishers, and the monitor lizard species common throughout the Tanintharyi coast. The Andaman Sea regime here is semidiurnal macro-tidal: spring range 4.0 to 5.0 m, though at the southernmost point of Myanmar — near the transition toward the smaller tidal ranges of the Strait of Malacca — the range is toward the lower end of that band compared to the Myeik latitude. The Pak Chan estuary current of 1 to 2 knots is the most practically significant local tidal feature; the longtail boat operators are experienced with it and the crossing times vary only marginally with tidal phase. The fish market operates from early morning on the incoming tide as the overnight boats return with Andaman catches — deep-water snapper, grouper, and the seasonal pelagics that make these waters productive. Predictions on this page come from Open-Meteo Marine (gridded model, ±45 min / ±0.2–0.3 m). The Kawthaung morning market operates from before dawn, with fresh Andaman fish, crabs, and the imported goods from the Thai trade trucks lining the road behind the market stalls. The market is at its most active on the incoming tide when the overnight Andaman fishing boats return and sell their catch at the pier end of the market. The walk from the main pier to the hilltop pagoda takes 30 minutes and gives a panoramic view of the Pak Chan estuary, the Thai hills on the other side, and the outer island horizon of the upper Myeik Archipelago. The passage between Kawthaung and Ko Chang Noi in Thailand is busy with cross-border ferry traffic; tidal current in the channel can reach 2 knots at spring tide and the local operators know exactly when to depart to take current with them. Recreational kayakers crossing should consult current tables, not just height predictions. The islands south and east of town are fringed with reef and mangrove; snorkelling conditions on the reef flats are highly tide-dependent, with the clearest water on the first two hours of the incoming flood when offshore water replaces the mixed lagoonal water. The morning market at Kawthaung pier fills with catches landed on the early flood; the fish auction is typically done by 08:00. The broader Mergui Archipelago begins here, and liveaboard dive operators working the outer islands read spring and neap cycles carefully — dive sites on steep walls are relatively tide-neutral, but submerged reef flats require enough water to be safe.
