Then you can go into options in google sync and turn on the calendar, and viola....you've got tides for free. It's not a surf report, per say, but it gets the job done for me. I usually know if there's surf coming so the only time I ever need my phone is to figure out tide.
There is also, in case anyone cares, a google map from tides.info that provides tides. Log in to google and create a personal map with the tide information for the area(s) you want and you can bring that layer up on google maps on your BB. It's working great for me right now.
