Windy! .........not Wendy

Checking out the forecast for today and its blowing 25 knots northerly here at Camerons Bight as per the Windy and Seabreeze forecast.
But Hobart's a different story as the forecast is for Northerlies with the southerly arriving late today. Meanwhile the real time Mt Wellington reading is a 40 knt southerly!
I haven't done a thorough check with BOM etc but it goes to show that if you where planing an early morning dash around the Tasman Peninsula before the change, on this info alone, you'd be in for a nasty surprise!
