What is the law of high tide and low tide in Qingdao?

First, the time of high tide is different every day, and 15 days is a cycle. Every day, the tide is divided into two high tides and two low tides. The difference between high tide and low tide is about 6 hours, and the high tide usually lasts for more than an hour before it ebbs.

Second, the second, third, sixteenth and seventeenth days of the lunar calendar every month are the spring tide period. At this time, the difference between high tide and low tide is very different.

In these days of each month, the sea water rises rapidly, and the highest tide level of the sea water is higher than usual. When encountering storm surge, the seawater will rise or fall abnormally, so tourists should pay special attention to safety at this time.

3. Every July and August, when there is a big storm at the seaside, if there is a big storm surge, the marine forecasting department will definitely issue an alarm to remind tourists and make relevant emergency plans.

Once a tourist is trapped on a rock, don't think that he wants to swim ashore because he is good at water, which is even more dangerous. Because there are many reefs in the front line of Qingdao Qianhai, if you don't understand the surrounding terrain, it's easy to be self-defeating Not only can't you save yourself, but you will harm yourself.

"It is the most dangerous to be trapped on a reef in windy days. If you encounter big waves, visitors must remember to hold their breath and avoid suffocation due to the huge impact of seawater. " Ming Jiang, captain of the Qingdao Red Cross Emergency Rescue Volunteer Team, believes that tourists who come ashore on their own are easy to be cut or even fatal by the reef.

After being trapped, tourists should always keep calm, use their mobile phones to ask the police for help, and try to ask the nearest person for help as loudly as possible when there is no mobile phone or the cell phone signal is not good.
