Best fishing times at Cong Do

Solunar bite windows for today and tomorrow, in local time: major periods (about 2 hours) when the moon is overhead or underfoot, minor periods (about an hour) around moonrise and moonset. A window with the tide turning inside it is the classic pick. Today's best bet is 4:47 PM–6:47 PM: the moon overhead. Solunar timing is folk wisdom more than science, so treat it as a tiebreaker alongside wind, light and what the fish are doing.

About this station

Cong Do is a tide station at 20.8500°, 107.3000° in Ha Long Bay. Predictions: the EOT20 global ocean tide model from satellite altimetry (DGFI-TUM, CC BY 4.0): modelled, not official predictions.

Cosmic's Coast Map shows these tides on a map of campsites, boat launches, hazards and marine forecasts, and, with a Coast Map Pass, saves a year of tide tables to your phone so they still work without signal. See everything the map does.
