Bellambi. Tomorrow if its rainy like the forecast says it will usually be squally, on for 20 minutes, not much for 20 min. Should be strong enough though.
If its fairly clear it will be good.
Bellambi is certainly the best but its also worthwhile to check out the latest weather observations for Albion Park (through BoM, weather zone) - its not perfect for the lake as its slightly inland from the SW corner of the lake, but the lake can quite often be different from Bellambi so the average of the two can be useful
