We use a number of online sites to forecast weather and determine flying conditions. We use:
www.metservice.com/Taylors Mistake or /Port Hills
Typically we need a N-NE-E costal wind to fly from our training site in the Taylors Mistake Valley.
We also fly at various other sites along the Port Hills of Christchurch and the Banks Peninsula. Generally these sites are for light wind days and are often sites with good thermal conditions.
