Apart from wind speed forecasts are there other factors or BOM information you consider before venturing out to get a better idea of wind conditions.

Sunrise and sunset

red skys at night sailors delight, red skys in morning sailors warning

i'm not sure whether you mean forecast or current conditions.

for current conditions i look at the bom stations, seabreeze, out the window, etc.

for forecasts i look at seabreeze, bom, gfs and ecmwf models then cross my fingers.

oh, and also moon phases. :)

I go by the bom, check the st kilda kite cam and if my curtains start blowing inthe wind it gives me signs.

the seabreeze one keeps changen i find its not that good to go by
