In this article, we'll find out what causes rip currents, how you can recognize them and what you should do if one takes you out to sea. A rip current is a narrow, powerful current of water running perpendicular to the beach, out into the ocean. These currents may extend 200 to 2,500 feet (61 to 762 m) lengthwise, but they are typically less than 30 feet (9 m) wide. Rip currents can move at a pretty good speed, often 5 miles per hour (8 kph) or faster.

In cold temperatures the wind also makes a difference, and in calm conditions at -29Â°C a well clothed person is in little danger, but if there is a light wind of 10mph it gives the same effect as a temperature of -44Â°C when exposed flesh can freeze in a minute or so.n the cold it really depends how well clothed you are! In Antarctics, temperatures regularly get to -60Â°C, and people can survive here if they have very good technical clothing that keeps their core body temperature within the normal range of 36.5-38Â°C.
