Doufujiao Diving Tides

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

Doufujiao: 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

Tofu Cape Recreation Area is south of Nanfangao Harbor and officially provides parking and toilets. Bring dive gear through the recreation-area lot rather than unloading beside the harbor channel. Official source
Without a car, transfer from Suao New Station or Suao bus terminal, or use G28/1879 to Nanfangao. Confirm carriage of bulky dive gear with the bus operator first. Official source

Water entry and exit

The official page confirms scuba and SUP but asks visitors to use a coach familiar with local land and water. “Open year-round” describes site access, not safe entry in every sea state. Official source
The bay contains block-like reefs and a coastal path, and the authority says to avoid deep and dangerous zones. Choose entries from on-site notices rather than crossing an unverified reef gap. Official source

Rinsing, parking and facilities

Official facilities list only parking and toilets. Plan toilet use here, but the published information does not promise gear rinsing, lockers or tank storage. Official source

Rules and ecological care

There is no resident site manager, and the authority explicitly says to avoid entering at night. Do not infer night-diving permission from year-round land access; verify rules and lawful supervision. Official source
For scuba or SUP, read on-site notices and assess ability first. Without a coach familiar with Tofu Cape’s terrain and water, do not independently explore deep zones. 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.

Does year-round access mean night diving is allowed at Tofu Cape?

No. The official page separately warns that the site is unattended and night entry should be avoided. Verify current rules and lawful local supervision for any night activity.

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.
