Red

The most often asked question when it comes to beach flag meaning is that what does a red flag mean at the beach? To answer it quickly, a red beach flag indicates high hazard with strong current, high surf, or another severe hazard.

In such conditions, you can swim at your own risk only but shouldn’t enter the water only if you absolutely have to go.

Red over red

Probably this is one of the most important beach flag meanings that you should take very seriously. Red flag over another red flag means there is an extremely high hazard with dangerous surf and current and the water is closed to public use, swimming is prohibited.

Red and white

When lifeguards put out the red and white quartered flag that means evacuating the water immediately. This could happen due to a variety of reasons such as sudden strong surf, current, hurricane conditions, or even sharks around, so if you see this flag, go to the shore as soon as possible.

Yellow flag with black dot

At beaches where surfing is typical, yellow flags with black circle in the middle are often used. These suggest that in that area the use of watercraft and surfing is prohibited ensuring that swimmers can swim there without worrying about surfboards and other watercraft passing around.

White-black flag

Black and white, or white-black quartered flags are used in pairs and indicate watercraft areas where non-powered watercraft like surfboards can be used. Swimmers should stay away from such areas for their own safety if there is a black flag at the beach.

Purple

This is that beach warning flag that not many people know but for your own safety, it is essential to learn what a purple flag means at the beach. It indicates that marine pest can be present in the water that can cause beach injuries. It can be not only purple but dark blue as well.

Usually, people think when seeing this safety flag that there may be sharks around the beach, but in such cases red or even double red flags are placed out. If there is purple flag, it notifies beachgoers that stinging marine life such as jellyfish, stingrays or algae can be around.

To decide if it’s safe to go swimming or not if there is purple flag, we recommend asking the lifeguard what type of danger the flag indicates.

Orange

Not exactly a flag, but still an important beach warning sign is the orange windsock that means there is strong offshore wind, and inflatable beach items or floats shouldn’t be used.
