In America,Virginia Beach has all the elements of a classic seaside resort:brilliant beaches,a lively boardwalk,plenty of restaurants and nightspots,and amusement rides sure to appeal to kids. Many believe Virginia Beach is at its best in the off-season,when the town is less crowded but the weather is still mild. Meanwhile,some safety tips should be followed,enjoying the happiness and excitement the beach offers. The number l safety tip concerns ocean safety:pay attention to Flag conditions posted on the lifeguard stands. Lifeguards post a red flag to warn when the ocean water is dangerous. Take them seriously! Tourists from land-locked regions are particularly easily attracted by the magic of the waves. However, a calm ocean can become risky without warning. Make sure you swim near a lifeguard. Swimming without lifeguard protection is almost five times as great as drowning at a beach with lifeguards. Never swim alone. Many drownings involve single swimmers. When you swim with someone else, if one of you has a problem,the other may be able to get help,including signaling for assistance from others. Don't fight the current. The facts show that some 80% of rescues by lifeguards at ocean beaches are caused by currents. These currents are formed by surf and gravity,because once surf pushes water up the slope of a beach,gravity pulls it back. This can create concentrated rivers of water moving off shore. If you are caught in a rip current,don't fight it by trying to swim directly to shore. Instead,swim parallel to shore until you feel the current relax,then swim to shore. Most rip currents are narrow and a short swim parallel to shore will help bring you to safety. |
