I searched for this topic but I didn't find any threads so if this is old news, my bad... but I was browsing the app store to find weather/buoy info that I could use before heading out and I came across 2 apps.
the first is Bombora

and the second is NOAA Buoy Data Reader

both are only a few bucks
