A tidal bore is a wall of water that moves up certain low-lying rivers due to an incoming tide. Tidal bores form when an incoming tide rushes up a river, developing a steep forward slope due to resistance to the tide’s advance by the river, which is flowing in the opposite direction. Thus we have the phenomenon of the river changing its flow before your very eyes, flowing in overtop the outgoing river water.
he height of the tidal bore increases with the range of the tide and may very in height from just a ripple to several feet.Bores occur in relatively few locations worldwide, usually in areas with a large tidal range (typically more than 20 feet between high and low water), and where incoming tides are funneled into a shallow, narrowing river via a broad bay. The funnel-like shape not only increases the height of the tide, but it can also decrease the duration of the flood tide down to a point where the flood appears as a sudden increase in the water level.
There are approximately two high tides and two low tides within a 24-hour period in the Bay of Fundy. The time between a low tide and a high tide is about 6 hours and 13 minutes. Therefore visitors to the Fundy coast can realistically expect to see at least one high and one low tide during daylight hours.
Tide times move ahead approximately one hour each day, and tide times vary for different locations around the Bay. One of the best ways to experience the full impression of the Bay of Fundy’s tides is to visit the same coastal location at high tide, then return about six hours later at low tide (or vice versa).
The Bay of Fundy tidal bore is a three hour drive from White Point Manor and White Point Beach Resort.
