Is there historical data for certain areas, IE St Kilda? The Melbourne Metro seems abit over the place.. does it average out all wind beacons combined?
BOM Weather Observations record historical data with all readings for all monitored stations:
Eg. www.bom.gov.au/products/IDW60901/IDW60901.94608.shtml
cheers
This is new, and gives average am/pm wind .. just click "last 30 days" on left of your states graphs page:
e.g. WA:
