Hello Friends,
The lull before the storms this morning. Just about flat at Dee Why but the low is winding up out at sea, so by tomorrow things should look very different. Right now swell at sea is almost straight south at a metre with a 13-second period. Lots of big clear patches in the sky, but by this afternoon we should be getting the first of the rain. Tomorrow is shaping to be rainy all day with SW winds and ramping swell. This morning sees the ECM model predicting SS
E 2-3 m tomorrow, 3-4 m Wednesday and then fading a touch to 3-3.5 m on Thursday. Wavewatch (which generally seems to be a bit closer to the mark) is saying 4-5 m SSE @13s Weds, 5 dropping to 3 Thr. Could be interesting…
Have a great day everyone.
Weather Situation
A trough of low pressure off the coast is deepening into a low pressure system, with its main centre forming over the Tasman Sea and the secondary centre developing off the southern coast. The low pressure system is forecast to linger in the region through to the mid-week, bringing vigorous southerly winds and large waves to coastal waters as the secondary centre heads north on Tuesday. From Thursday the low is expected to weaken and move away to the east, as a ridge of high pressure develops over southeast Australia.
