In the case of Fundy tides, the “swing” is the shallow body of water between the edge of the continental shelf east of Boston and the head of the Bay of Fundy. If the timing is poor, the swing will not move much. The parent must time the pushes to closely match the natural period of the swing, a condition called resonance. A gentle, repetitive push by the parent will sustain a large back-and-forth motion of the swing. Imagine a parent pushing their child on a swing. Why are Fundy tides so high? Resonance - like a push on a swing Select time zone AST for dates before March 10 and after November 2, 2024.

Occasionally, because of much rain and/or rapid snow melt, the river may be too deep for a tidal bore to form.

The largest tidal bores in the Salmon River occur on the days of perigean-spring tides ( the Moon closest to Earth and at its new or full phase). Why does the size of the tidal bore in the Salmon River vary? If a tidal bore encounters water that is much deeper than the height of the bore, the bore collapses into a barely noticeable, smooth surge of rising water. Shallow river water – The water in the river prior to the arrival of the bore must be relatively shallow.Higher riverbed – The riverbed must be well above the level of the low tide so that the tide is rising rapidly when it enters the part of the river where a tidal bore might appear.Almost flat riverbed – The riverbed must have a very gentle, downstream slope.Three conditions are necessary to form a tidal bore: However, a tidal bore does not occur in every river flooded by a high tide. Tidal bores occur in regions of the world that have large tides. 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 6 hours later at low tide (or vice versa).A tidal bore is a tumbling wavefront which moves upstream in a river, announcing the arrival of an incoming tide. The incoming tide reverses the outgoing flow of the river, causing a standing wave, known as the tidal 'bore' to flow back up the river. Tidal bores and rapids are another effect. You can experience those across the Minas Basin from Five Islands on the Shubenacadie River in the Maitland area. In areas such as Five Islands, the tide retreats as much as 5 km (3 miles) at low tide, leaving vast areas of the ocean floor exposed at various times in the tide cycle (changes daily). In additional to the vertical effect, there is also the horizontal effect of the tides. What are the other tidal effects visitors can see? This effect can also be viewed at Five Islands Provincial Park. There, you can witness the vertical tidal effect: a harbour previously full at high tide will look like someone pulled the plug on it at low tide. There many small harbours around the Bay that are empty at low tide and then completely full about 6 hours later at high tide, including the Parrsboro Harbour, only 20 minutes west of our run location in Five Islands. Where can I see one of those cool harbours where boats on are on ground at low tide? The site of the highest recorded tides was in Burntcoat Head, Nova Scotia, just a few kilometres across the Minas Basin from our run location in Five Islands, Nova Scotia.

Where were the highest tides actually recorded? The equivalent outflow of all the world's fresh water rivers is less than the amount of water that moves out of the Bay of Fundy on one tide that's 100 billion tonnes of sea water! How much water goes out with one Bay of Fundy tide? Tide height is normally measured as vertical distance: the change in the ocean’s elevation from low tide to high tide.

Therefore, the predicted high and low 'tide times' in the tide cycle move ahead by 52 minutes each day. It takes 6 hours and 13 minutes for the tides to go from low to high, and vice versa. According to Guinness World Records, and other world renowned sources, the Bay of Fundy has the highest tides on the planet: 16.8 meters (54.6 feet).
