graphs like this

that show the Min, Avg and Max windspeed.
my session today according to bellambi wind meter which I could see from the beach said between 21-27kts. real life said 5-27kts.

its not the big gusts that annoy me during winter its the lulls. would be nice if the BOM included a 3second average of lowest windspeed in their data like they do for gust calculations..
