Dull skies, dull waves at Dee Why

Posted by: on November 28th, 2010

Hello Friends,

Wind is going along from the NNE at 15-20 kts this morning under grey skies. The MHL buoy off Sydney is showing two metres of 7 second east wind swell, but it sure isn’t anything like 2 metres at Dee Why. Every now and then a just barely catchable little thing flips over at the point. However if there are any waves bigger than waist high, I’d be very surprised. At around 0830, there was a single bodyboarder chasing the aforementioned bumps, and a few beginners messing around in the knee high dribble at kiddies. Obviously not the first place to check for a wave this morning.

The wind is set to back off by this afternoon according to the forecast, but it seems to me to have already done so. With the drop in energy input, I’d expect the little wind swell to weaken further.

The latest run of the models suggests our surf prospects in Sydney are slumping toward flatness across the middle of the week. However, the Bureau’s version of the data is currently saying we might have another NE wind swell day on Tuesday. Hope they’re right and that the other interpretations are too pessimistic. At the outer extreme of the forecasts, there seems to be hope of some longer period east swell for next weekend… wouldn’t that be good!

Have yourself a good one!
