Windfinders.com is pretty accurate up here....All the kite boarders and surfers use it.......I like it on account of its showing the inbound Wind directional patterns, rising or declining velocities etc...so some beaches will be sheltered, and some not...
Its taking the readings from the offshore bouys..so a guy can use it to preplan a hunt ahead of time if the wind is steady and prevailing...we have a small window to hunt right during the slack and turn of a big onshore blow and corresponding rip....maybe only a few hours before it all slumps in again... of course the beach webcams are important...
