Rip Current Science

You might have heard them referred to as undertow
or rip tides, but these ocean phenomena are actually rip currents. Rip currents are narrow currents in the surf
zone that move quickly away from shore. A typical rip current ranges from 50-100 feet
wide, and can extend 100 yards or more offshore. It can reach speeds of over 5 miles per hour
- thats faster than an Olympic swimmer! That makes them dangerous and potentially
deadly, and scientists want to learn more about them so we can better forecast when
and where they will form - and keep beachgoers safe.

Heres what we know: Waves dont have to be huge for a rip current
to form - two or three feet are all it takes. And the weather doesnt have to be bad for
a rip current to emerge. They often occur in the nice days after a storm. Theyre usually strongest near low tide,
but can form at any time.

Rip currents often form where sand bars are
near the shore. They occur at breaks or channels in the bar. Theyre often difficult to see, but you
can spot them in areas where waves arent breaking, or where theres foam, seaweed,
or discolored water being pulled offshore. Its easier to see a rip current from higher
up - such as from the beach access over dunes or a lifeguards tower.

Rip currents are a hazard for beachgoers,
but by knowing the dangers and what to look for, you can avoid being caught in the grip
of the rip..
