Hello Friends,
No sign of any significant swell this morning at Dee Why. But then again, the predictions have consistently been for the energy to start building late today.
The offshore data from the Sydney MHL buoy is showing a metre at an average of 6 seconds from the ESE. There is some longer period 11 sec stuff in the mix, so if you sit around long enough there could be the odd bigger set.
Down at Eden, MHL’s buoy is showing the swell jumping from around the same size at midnight to nearly three metres at the latest run of data. The period setting is still a very short 7 seconds though, so what’s showing down there isn’t groundswell. This is consistent with the various prediction models, which are currently showing the swell initially coming from the south at around 7 seconds.
Overnight, if all goes to according to the latest run of the models, the swell should push up into the three metre range as it moves around to the SSE and the period stretches out to 10-11 seconds.
Of course this energy is going to arrive with lots of wind. The Bureau’s saying that we’ll be looking at S-SW 20-30 kts from late today through Wednesday. And the weather will be grey and showery from the sound of it.
Naturally we’ll be keeping a close eye on things and of course I’ll be hoping to get a few pictures as well (I’ve got the new Canon 7D to test).
Synoptic Situation
A Low in the Tasman Sea to the east of Bass Strait is expected to remain semi stationary during today and Tuesday, moving only very slowly to the northeast, and then move further east during Wednesday. Meanwhile a High in the Bight is expected to pass over Tasmania on Tuesday and to the southeast of Tasmania on Wednesday. This will result in fresh to strong southerly winds along the New South Wales coast today and tomorrow, easing and turning more southeast on Wednesday.
