1. Watch the TV weather forecast or call the meteorological station the day before diving activities, which can be used as a reference before activities. If the typhoon is approaching, but the weather is still fine, it is not appropriate to arrange diving activities at this time. Although the weather is sunny and hot, the waves fluctuate abnormally and the visibility is getting worse. It is quite dangerous to go to sea at this time; Sometimes on normal days, when the weather is "fine", I go straight to the beach without asking indiscriminately. It is not until the scene that the waves can't enter the water, and a large number of people are watching the waves on the shore. Sometimes the weather is cloudy, cool and rainy in Mao Mao, which seems unsuitable for diving, but the sea conditions are calm. It can be seen that the advantages and disadvantages of weather and waves are not absolutely accurate, and the changes of waves are often changing rapidly. Therefore, if you feel uncertain or the weather is weird before diving that day, you'd better call your seaside home and ask about the sea conditions to avoid a trip in vain. Although the distance is not very far, it is quite tiring to move a lot of equipment up and down.
Therefore, it is best to have a home phone near the diving field where you often go. Usually nearby fishing gear shops or diving equipment shops, fishermen and their families will enthusiastically and correctly inform you of the sea conditions or wave levels at that time. With the correct information about the sea conditions, I can judge whether I should carry out this diving activity, or whether I should change to a diving field to reduce the pain of running around. If you come to the seaside in a hurry, but the sea conditions are not good, please don't rush into the water. Visibility will be poor when the waves are big, and it is more dangerous to go ashore. Even after entering the water, it can only be described as regret.
2. Between the rocks or on the top side of the rocks that bear the current, the current is usually turbulent. If you know that your feet are not strong enough or there is not much air left, you should stay away from them, otherwise it will easily be washed away by the current and affect the diving plan.
3. Pay attention to the highest full tide and lowest tide of the diving field. As long as you make full use of your stay time, I believe you can make your diving activities easy and safe.
