Derby – sunsets and big tides

Tides are the periodic rise and fall of sea level resulting from the gravitational interaction and motion of the Sun, Moon and Earth acting on ocean waters. Tidal patterns are modified by other influences such as the shape and depth of oceans and the weather. The combination of factors is complex and causes local tides to vary greatly from one site to another.

Derby has Australia’s highest tides and one of the highest in the world.

The Bay of Fundy, Nova Scotia, Canada, has 15m tides. Other high tides occur at Bristol (UK) 14.6m, Mont Saint Michel (France) 12.3m, Puerto Gallegos (Argentina) 13.2m and Bhaunagan (India) 12.2m. Home in Kerikeri a big tide will only be about 2.7 m

High tides in Western Australia are Derby 11.8m, Yampi Sound 10.9m, Broome 9.8m and Wyndham 8.4m. Also had some fantastic sunsets over the wharf where Barb and I has dinner tonight watching the sun disappear
