Wind Direction vs Wave Direction - confused

Post by skouta » Fri Feb 23, 2018 3:43 pm

I was just looking at Buoyweather and I am a little confused.

Current wind direction in PPB is listed as NNE.

Current wave direction in PPB is listed as WSW.

So the wind is coming from the North but the waves are coming from the West.

I thought they would flow the same direction as the wind but I'm obviously wrong...

Can someone help me understand...

Generally it does but if the wind has just changed direction then it takes a while for waves to change too. And in Melb the wind can change around alot!

Buoyweather uses swell height and direction, that found in bass strait and lower ppb which most times comes from the sw direction and the giveaway is the 11 second gap, not the waves created by the wind like you're thinking. Wind waves will always come from the same direction as the wind and grow as wind gusts strengthen
