Bored with ocean surfing? Thought about taking a wave down ye olde river? That’s right – I’m talking about
tidal bore and the
sport of bore surfing. This
National Geographic article
talks about this interesting recreational activity and how these inland waves form. In summary, a tidal bore occurs
when a wave forms from tides as they head into certain rivers and only under certain environmental conditions. Some
bores can travel up to 20 miles an hour and get stronger as they go up the river, creating a unique surf condition
which has sometimes been sighted many miles inland.
