Today's tide forecast for Nanwan Beach: high and low tide times, tide heights, tidal range and wave conditions. Data from Taiwan CWA, updated daily.
Shore diving and snorkelling are safest — and usually clearest — at slack water: the window around high and low tide when the current turns and runs weakest. Mid-tide is when the current is strongest and least suitable for getting in.
Below are estimated slack windows of about 1 hour around each high and low tide today. Actual current, swell and visibility still depend on wind, terrain and weather.
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.
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.
