NOT A LOT OF PEOPLE KNOW THAT . . .

The biggest tides are in the Bay of Fundy (Nova Scotia) where a range of 57ft (17.4m) is sometimes recorded

At Nokwakto Rapids (British Columbia) a tide speed of 16 knots has been observed.

The tidal bulge, scraping along the bottom of ocean shallows, slows the Earth’s rotation by one second every 1000,000 years

Off the island of Euboea (Greece), the tidal current changes direction some 14 times a

day. So far, nobody can explain why.

The tidal cycle averages about 29.5 days and is reflected by the reproductive cycle of many plants and animals, including Homo sapiens.

Even though New Moon and Full Moon exert the greatest gravitational pull on tides, there is such a huge mass of water to be shifted that the effects of these astronomical phenomena are not felt until about 36 hours after they occur.

Spring and neap tides tend to occur at the same time of day at each cycle in every location, e.g. – Dover HWS at 12.00, LWS at 12.30.
