About the tides at Saint-Laurent I.O.

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.62 m. The tide range here is very large, about 4.19 m on average. Water can come in faster than you can walk across flats. Check the time before you go out. That is larger than most Quebec stations on this site. The next spring tides peak on October 28, with a range of 5.70 m. Neap tides follow today, when the range shrinks to 3.35 m.

Saint-Laurent I.O. is a CHS station with a live water level gauge. Predictions come from the station's own tidal analysis. It was established in 1966. The nearest other station is Saint-Jean I.O., 10 km away, where high tide comes about 15 min earlier. Canadian tide heights use chart datum, a level set low on purpose. Negative heights are uncommon.
