Ludao Shilang Diving Tides

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

Ludao Shilang: 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

Shilang adjoins Nanliao and is officially addressed as the Shilang Diving Area. Gear up at the marked dive area rather than treating the adjacent Nanliao quay as its entry. Official source

Water entry and exit

Shilang is officially identified for scuba and snorkelling along a gently extending coral coast. Use established dive facilities to enter and avoid stepping on live coral or intertidal organisms. Official source
Official advice says not to go far offshore because currents strengthen and glass-bottom semi-submersibles operate outside. Preserve a return route and do not pursue features toward vessel lanes. Official source

Rinsing, parking and facilities

Shilang’s official facilities list includes a payphone, fuel station and lookout, but not toilets, parking or public rinsing. Arrange supplies and gear washing with a lawful dive operator. Official source

Rules and ecological care

Official advice says stay out in poor weather, use a lawful dive business, follow the instructor and never go alone. “More stable current” does not mean no current or no supervision. Official source
Shilang’s coral and intertidal life are active. Official guidance prohibits collecting organisms and leaving waste; observe the underwater postbox and reef without touching, stepping or removing life. 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.

Why should divers stay close to shore at Shilang?

Currents strengthen offshore and glass-bottom semi-submersibles operate there. Keep a return line, follow a local instructor and avoid vessel routes.

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.
