Excuse me, which website is better for inquiring about ocean weather!

How about going to China Meteorological Network /cma_new/tqyb/zhyj/

If you only care about the marine weather in a certain place, you can look it up directly on the internet, such as "Hainan marine weather forecast", which may be better. If it is nationwide, it will be even harder to find. After all, this aspect is relatively rare. If you are an ocean fan, you can go to China Ocean Culture Online to see /cma_new/tqyb/zhyj/
