Just saw this on Facebook, All surfers should check this out - http://www.wavealarm.com.au/ Only wakes you when the waves are up to the quality you want as a minimum. 
pretty sure I used to live next door to the kid that made this! Or at least had this idea!
What?! ...and ruin the feeling of jumping out of bed early to drive around all the usual haunts looking for the right wave?
Please don't take that away - it's one of the only things that get me out of bed early in the mornings!
