I use this all the time. Its accurate and easy to use. Actually reports buoy data so there is no prediction, its fact. I have sat next to bout 10 miles offshore and temp and swell dead on. I wish it did some swell map predictions and some SST predictions but I doesnt that I can find. Oh well, like I said its a ample app that works great.
