A tidal bore is a surge. A tidal bore is a tumbling wavefront which moves upstream in a river, announcing the arrival of an incoming tide. Tidal bores occur in regions of the world that have large tides. However, a tidal bore does not occur in every river flooded by a high tide.High and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.Surfing tidal bores and river waves is possible and can be done safely. Bores only happen in a few places in the world and may only hit your spot once a year. If you’re lucky, it’s the ultimate experience. This particular wave is usually consistent and strong due to the funnel-type effect on the riverside.There are approximately 60 tidal bores in the world. All range in wave height, frequency and distance. They reach up to 30ft in height, travel at speeds close to 25mph and run up river for hours- could you stay on a wave that long?In places where an incoming high tide enters a shallow and sloping estuary, river, or harbor, the higher water level can form a wave called a tidal bore (SF Fig.

Different Types of Tides. As the moon rotates around Earth, there are different types of tides that can occur, as Earth revolves around the sun. Tides can be classified into 3 groups, which are high tide and low tide, semidiurnal and diurnal tides, and spring and neap tides.Semi-diurnal tide The most common tidal pattern, featuring two high tides and two low tides each day [Actually it varies between 3 tides to 4 tides –– 3 tides in rare cases but 4 is normal]. The successive high or low tides are approximately of the same height.
