Ludao Port Diving Tides

Before diving at Ludao Port, check tide turns and wave conditions. Slack-water timing is only a reference; follow instructors, local rules and site conditions.

Ludao Port: seven-day slack water and daylight

Each slack-water range is estimated as 60 minutes either side of high or low tide. The stronger-daylight range is four hours centred on the midpoint between sunrise and sunset. Both are planning windows, not declarations that conditions are safe.

Tidal range, spring and neap tides, and the Moon

Spring tides often occur near new and full moon, with a larger difference between high and low water and potentially stronger flow during the middle of the turn. Neap tides are more common near first and last quarter. Local current is not set by astronomical tide alone: wind, swell, seabed shape, and narrow harbor entrances all alter what divers encounter.

Spring tides usually occur near new and full moon and have the largest tidal range; mid and neap tides have progressively smaller ranges.

Sunrise, sunset, and underwater light

Once the Sun is higher, its light travels a shorter path through the water. In clear water with a settled surface, the hours around solar noon usually reveal terrain and color better. Low-angle light at dawn and dusk fades faster underwater. The table's daylight window is not a visibility forecast; suspended sediment, runoff, and waves remain decisive.

Verified access, entry and facilities

Only official or owner-confirmed information is shown. Unverified drafts stay off the page. Check same-day notices and on-site controls before departure.

Getting there with equipment

• This Ludao Port page refers to Nanliao Harbor. The official crossing from Fugang takes about 50 minutes; confirm carriage restrictions with the ferry company before bringing tanks or oversized gear. Official source

Water entry and exit

• Nanliao is shared by fast ferries, leisure craft, glass-bottom boats and fishing vessels. The basin and berths are not general shore entries; distinguish harbor operations from nearby Shilang. Official source
• The official harbor camera identifies Shilang to the left of Nanliao Harbor. Use the marked Shilang area for shore diving rather than entering from the passenger-cargo quay to shorten the carry. Official source

Rules and ecological care

• Ferry arrivals concentrate pedestrians, vehicles and vessel work at the harbor mouth. Official traffic separation and short-stop controls mean divers must follow same-day directions and keep gear off the quay. Official source
• Use officially identified areas and dive paths such as Shilang and Chaikou with a qualified operator familiar with currents, bottom structure and hazards. A harbor tide page cannot replace site assessment. Official source

FAQ

Should I dive on a rising or falling tide?

What matters is slack water, not rising vs falling — the current is weakest around high and low tide, which is best for shore diving and snorkelling. Mid-tide has the strongest, most dangerous current. Match your entry to that day’s tide times and aim for the slack window.

How do I know the best time to get in today?

Check today’s high and low tide times on this page; the roughly 1-hour window around each turning point is slack water with the weakest current. Still confirm the day’s wind, swell, visibility and weather, and defer to your dive shop and on-site notices.

Can I enter the water as soon as the table shows slack water?

No. Slack water is only an estimated period around an astronomical tide turn. Waves, local current, visibility, entry and exit conditions, and closures still require an on-site check. Use a qualified instructor or guide when your training or knowledge of the site is not sufficient.

Is Ludao Port itself a shore-diving entry?

No. Nanliao is a working passenger-cargo harbor, while nearby Shilang is separately identified as the dive area. Move to the marked site and avoid harbor operations.

Tide times and heights come from the site's daily CWA forecast. Sunrise, sunset, and lunar phase are calculated at build time with the same astronomy engine used by the live pages.
