About the tides at Rivière-au-Tonnerre
Rivière-au-Tonnerre has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. With a mean range of about 1.54 m, the shoreline here changes a lot between high and low water. That is smaller than most Quebec stations on this site. Over the next two weeks the biggest daily range, 2.34 m, comes today, and the smallest, 1.36 m, on October 7.
Predictions for Rivière-au-Tonnerre come from this station's own tide records. There is no live sensor, so the table shows forecast only. It was established in 1962. The nearest other station is Mingan, 53 km away, where high tide comes about 21 min earlier. Heights are measured from chart datum, which in most Canadian tidal waters is set near the lowest normal tide. That is why lows here rarely go below zero.
