Hi Satan [}:)],
Jan and Feb will be fishing or surfing in the morning and kiting until it hurts in the afternoon.
Generally old Beelzebub, "prince of the devils" the wind kicks reliably after 2pm most regularly NE during summer. I've found it reliably over 15 knots near every hot sunny day.
You'll find old 'Spirit that now Worketh in the Children of Disobedience', Pippy beach will be the highlight, I recon. Can hold a bit of swell, especially if there is a storm out at sea. Excellent lefts.
And while you're down there old Nick, Angourie back-beach might be a very pleasant secluded area for the kite as well. Steer clear of the surfers though as this was where the infamous fight Nat Young had with another local and broke his Shnoz (perhaps you know too much about this mischief already Chief Spirit of Evil and Adversary of God).

Now you old serpent, there is one other spot that as an old windsurfer was way cool. Whiting Beach. It's on the inside of the Clearance River. It gets real smooth behind a rock wall and the wind is a little stronger due to a funelling effect. This may be too difficult to find and perhaps v difficult to launch from Whiting Beach during summer (peak periods).
Oh...as LotofWind suggests Iluka too has open beaches and nice waves with some points with left and right breaks. Wicked! My unfamiliar Diabolos.
Constant enemy of God, enjoy the night life, go to the Pacific hotel for a beer during light time, a view all salt dogs enjoy!
Smiles,
Rod.
