Rip currents on the Atlantic beach: spotting one and getting out
Rip currents are the number one hazard at a surf beach. How to spot one before you enter the water, what to do if one carries you out, and what the official sources say about when they are likely.
A rip current is not a large wave. NOAA describes rip currents as powerful, narrow channels of fast-moving water (NOAA National Ocean Service). The National Weather Service calls them strong, narrow, seaward flows that extend from close to the shoreline to outside the surf zone, found on almost any beach with breaking waves (NWS Rip current science).
They matter because of the numbers. NOAA and the U.S. Lifesaving Association describe rip currents as the number one hazard at a surf beach, leading to tens of thousands of lifeguard rescues and over 100 drowning deaths every year in the United States (NWS toolkit).
How strong, how wide
The NWS gives these figures for the best-documented type, the channelized rip current (NWS Rip current science):
| Property | NWS figure |
|---|---|
| Typical flow speed | about 1 to 2 feet per second |
| Fastest speed | up to 8 feet per second |
| Typical width | 5 to 100 yards |
| Typical depth | 3 to 10 feet or more |
| Spacing between rips | 50 to 500 yards |
The NWS compares the strongest speeds to those of some of the fastest Olympic swimmers, and says that even a strong swimmer who tries to swim back against the flow can quickly become exhausted. It also notes that a rip current’s speed is not constant: a “rip pulse” is a sudden acceleration lasting 30 seconds to a minute, linked to sets of larger waves breaking, and during a pulse the flow can more than double.
How to spot one from the shore
The NWS offers these tips for spotting rip currents:
- Look from an elevated position, such as a dune crossover, a beach access or a car park overlooking the beach.
- Watch the water for several minutes, because conditions change.
- Look for a darker, narrow gap in the lines of breaking waves, heading offshore.
- Look for narrow bands of choppy, rippled water heading out.
- Look for foam or sand plumes beyond the breakers, moved away from shore.
- Look for scalloped cut-outs in the beach edge, which long-lasting rips can erode.
- Ask a lifeguard if there are rip currents and to point them out.
If you see any of these signs, do not enter the water at that spot. Not seeing them is not proof that there is no rip current: flash rips are less predictable and appear as narrow bands of turbulent water and sand.
What you must never do
Do not try to swim straight back to shore against the current. NOAA says panicked swimmers often do this and risk drowning from fatigue, and the National Hurricane Center says not to try to swim directly back to shore or against the breaking waves (NOAA, NHC).
What to do if you are caught
The NWS Newport/Morehead City office, which covers this stretch of coast, gives these steps (NWS Newport/Morehead City):
- Stay calm to save energy and think clearly.
- Do not fight the current. Think of it as a treadmill you need to step to the side of.
- Swim parallel to the shoreline to get out of the current.
- Once out of it, swim at an angle away from the current toward shore.
- If you cannot swim out of it, float or tread water calmly, and swim toward shore once you are out of the current.
- If you still cannot reach shore, wave your arm and yell for help.
NHC adds that rip currents do not pull you under; they pull you away from shore (NHC). The NWS likewise says the idea that rip currents or undertow pull people under is a myth.
If someone else is in trouble
Get a lifeguard, or have someone call 911 if there is no lifeguard. Throw the person something that floats, such as a lifejacket, cooler or ball, and shout the escape instructions. Do not enter the water yourself: the NWS Newport/Morehead City office warns that many people drown while trying to save someone else.
Before you go in
- Swim where lifeguards are present. The NWS says to swim only at beaches with lifeguards, and cites the U.S. Lifesaving Association for a chance of drowning at a guarded beach of 1 in 18 million (NWS).
- Never swim alone.
- Check the forecast and ask the lifeguard. The NWS says to look at the local beach forecast before you leave and to talk to the lifeguard at the beach.
- Keep clear of piers and jetties. The Newport/Morehead City office advises staying at least 100 feet from piers and jetties, where permanent rip currents often exist.
Weather and conditions: what the sources do and do not say
Good weather does not mean a safe beach. The NWS states that rip currents often form on calm, sunny days (NWS).
The NWS Newport/Morehead City office publishes a rip current risk level for the day, and the levels are defined by wind and/or wave conditions. At the low level, wind and wave conditions are not expected to support the development of rip currents, though rips can still occur near groins, jetties and piers. At the moderate level, wind and/or waves support stronger or more frequent rip currents and only experienced surf swimmers should enter the water. At the high level, wind and/or waves support dangerous rip currents that are life-threatening to anyone entering the surf. Treat the day’s published level, not your own judgement of the sky, as the starting point.
The NWS science page explains that rip currents are driven by breaking waves and form where wave breaking varies along the beach, so a gap in the line of breaking waves is the signature to look for. Hurricanes can also cause rip currents, according to the National Hurricane Center, which is one reason to check official forecasts during hurricane season.
Rip currents are not the only hazard. The NWS also warns against turning your back on the ocean.
This does not replace lifeguard instructions
This article summarises official guidance and is general information. At the beach, the authority is the lifeguard. If a flag or a lifeguard tells you to stay out of the water, follow it, even when the sea looks calm to you.
