This lets you know what you could expect. Most buoys worldwide, except buoys found in Canadian waters and maintained by Environment Canada have this infomation, just look under Historical Data.

Click on area of interest then on your buoy. You can look up among other items,Air and Sea temps,Peak wind,Wind gusts, Significant wave heights and Average wave period.
