Try these:
NQ Coastal Obs.
www.bom.gov.au/qld/observations/coastal.shtmlLow Ilses is the closest point to Port Douglas, but bear in mind it is a little offshore so out in a stronger trade flow.
The AIMS weather station at Agincourt Reef.
www.aims.gov.au/pages/facilities/weather-stations/agincourt.htmlOut at the edge of the shelf opposite Port Douglas.
Buoyweather is my personal choice for the forecasting side of it, but you have to subscribe for the longer range material...worth it though IMHO.
This is the virtual buoy closest to Pt Douglas:
www.buoyweather.com/wxnav6.jsp?region=AE&program=nww3BW1&grb=nww3&latitude=-16.0&longitude=146.25&zone=10&units=eand of course the best one of all....
...go down the beach and have a look at the whitecaps, and put up your choice of wind weapon!!
