Tristan, Windguru is good for forecasts for Sandy Point:
www.windguru.cz/15753 - you can also use the options button top right and apply Mat's correction which gives a better reading for S to W winds, although it ends up similar to the recently added "wind gusts" figure.
Haircut, Sandy Point can be good in a N or NW if you head out left from the carpark area and up towards Yanakie - long runs up there on any tide - across the shallow water over banks on a high tide and in the channel in the low tide.
I am hoping to head to Inverloch tomorrow (Sat) with my partner Lari for more lessons for her - if she doesn't imbibe too much "festive spirit" tonight!
