🏖️ Recommended Activities
At low tide the waters tend to be calmer.
Access only within the 2 hours near the lowest tide.
Ask the skipper about the conditions.
🎣 Solunar Table
Major Periods (2h)
Minor Periods (1h)
Based on the Solunar Theory (John Alden Knight): fish and wildlife tend to feed more during the periods when the moon is overhead or underfoot (major) and at moonrise/moonset (minor). The score considers the lunar phase and the crossing of major periods with the local high tide.

📘 About Shanghai Tide Forecast
The coordinates for Shanghai (31.23° N, 121.47° E) place this stretch of China's coast in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 3.5m and spring tides reaching up to 5m (values estimated from nearest harmonic station). With tides above 3 metres, ebb current speeds can exceed 2 knots in narrow channels, requiring extra caution from mariners. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. Data from this station feeds into the global sea-level monitoring network, contributing to long-term change research. This page shows the complete 2026 tide table for Shanghai, with precise high and low tide times and heights in metres for every day of the year. In September, Shanghai is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. All tide predictions are computed from harmonic constants validated for this coastal station, with accuracy within ±15 minutes for most conditions.
