NOAA weather, it is on our home page here. I also check the Belmar cam. You can get a general idea of what the ocean looks like. It is deceiving at times though. Looks good on the cam, but can be rougher than it appears on the cam.
The most accurate weather I check is...taking a ride to the ocean and seeing for myself!
There have been days where the ocean would have been ideal for fishing but the weather report made it sound like big seas and no way to get out. There are also days where the weather forcast said 10-15 knot winds and you have steady 20-25s.
If you are not too far, always best to ride down and check it out yourself. Use the weather sites as a guide only.
