There are about 260 bores in each year occurring twice a day on 130 days. Because the bores are associated with the phases of the moon, one occurs between 7 a.m. and noon on bore days, and the other between 7 p.m. and midnight GMT, with the largest bores occurring between 9 and 11 in both the morning and evening.
How often is the Severn bore wave?
approximately 250 times per year
The bore occurs approximately 250 times per year, ranging from a small ripple to the highest waves. However it is generally at its best when a very high spring tide is predicted, something in excess of 14 m at Avonmouth.
How often does a tidal bore occur?
Tidal bores can occur every day, like the tidal bore of the Batang River in Malaysia, called the benak. Other tidal bores, like the pororoca, occur during spring tides. Spring tides happen during new moons and full moons, when tides are strongest. Tidal bores almost never occur during neap tides.
When should I watch the Severn Bore?

How far does the Severn Bore travel?

How many times do you pass through a tidal bulge in a day?
Coastal areas experience two low tides and two high tides every lunar day, or 24 hours and 50 minutes. The two tidal bulges caused by inertia and gravity will rotate around the Earth as the moons position changes. These bulges represent high tides while the flat sides indicate low tides.

What does a tidal bore look like?
Tidal bores occur during flood tides when the tide is flowing towards land, often upstream. To an observer on the bank, an approaching tidal bore looks like a turbulent wave or “wall” of water that suddenly raises the water level.
Can you see the tidal bore?
The Tidal Bore can be best viewed at the Fundy Discovery Site in Truro and the Fundy Tidal Interpretive Centre South Maitland. These sites will also list the times of the tidal bore. My Bay of Fundy map will help you locate these places along the bay. Some folks opt for the more adventurous way to see the Tidal Bore.
