I use BOM, its usually fairly accurate and use Seabreeze for to show trends and timing. Seabreeze is often well under the real local breeze. For offshore work I consult www.buoyweather.com. Find a buoy near to your location and set it up. Its very good.
Another page I used to use for fishing was www.heavens-above.com/main.aspx Mainly the daily sun and moon times. You set your own lat and long or location by town. I used it for finding exact moon rise and set times and inclination for purse seining at night. It would also be handy if your planning a night passage and trying to calculate how bright or dark its going to be.
Link from this mornings yachting and boating forums that is interesting;

Seabreeze in wa conditions I find to be more accurate than bom. Only when seabreeze and bom align are they both right and in we that means a very strong 25+ knot ssw . I would put seabreeze at 90% accuracy.
