What is a tidal bore?
This is a natural phenomenon which is seen in very few
parts of the world. The Bay of Fundy is particularly noted
for its extremely high tides, the highest in the world, and
for its tidal bores.
As is generally known, the rise and fall of ocean tides is
caused by the gravitational “pull” of the moon on the earth’s
watery blanket. At most places along the ocean shores, high
tides occur regularly every 12 hours, 25 minutes.
In the open ocean the tide only rises and falls a fraction
of a metre. However, in most V-shaped bays and inlets the
tide enters the broad end and the water literally “piles up”
as it moves up the bay. In certain areas, such as the Bay of
Fundy, the natural period of oscillation is very close to the
tidal period and, just like water sloshing back and forth in a
bowl, the rise and fall of the tide is greatly amplified.
Thus, the tide water enters The bay at its widest point,
and as it passes along toward the head of the bay, it is in
effect squeezed by the ever-narrowing and by the constant
“shallowing” of the bottom.
At the very head of the bay this advancing tide becomes
a wave varying from just a ripple to several feet in height,
and this wave continues into and up the rivers which
empty into the bay. This wave is referred to as the “Tidal
Bore”. -Thus, we have the phenomenon of the river chang-
ing its flow before your very eyes, created by the tidal wave,
or bore, flowing in OVER the outgoing river water.
The height of the tidal bore increases with the range of
the tide. The range of the tide varies with the phases of
the moon, the distance of the moon and other factors and
can be obtained from the Canadian Tide and Current Tables
published by the Department of fisheries and Oceans.
This wonder of nature may be seen from your car at the
free parking area near highway 102, just outside Truro. As
noted, the actual bore may vary in height from just a ripple to
several feet.The important factor is the tremendous inrush
of water and the extremely rapid rise in the water level
immediately following arrival of the bore. In fact, high tide
at the Truro viewing site is reached in just over one hour
from arrival of bore.
