The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks at our local zone.
Right off the bat, we've got a bit of a slow start. The first real call is for Sunday morning with a solid 8ft southerly swell. That's got some serious energy behind it – we're looking at a combined energy of 1615, which is strong. The wind is a cross-off from the WSW at 16 mph, so it'll be a bit bumpy and the tide might be a factor. It's more for the seasoned intermediate crew.
Monday the 7th morning is a nice little window. The swell drops to 5ft from the SSE, the wind goes light offshore from the NNW at 3 mph, and things clean up. Water temp is sitting at 63°F, which is pretty average for this time of year, nothing weird going on. This is a nice, clean morning session.
The standout, the one you've been waiting for, looks like Monday the 14th afternoon. The swell is a consistent 7ft from the ESE, and the wind turns light and cross-off from the north at 6 mph. The energy is still solid at 883. Conditions should be really good, with clean lines. This is the pick of the period.
Tuesday the 15th is also worth a mention. Morning starts off glassy with a light offshore from the NW and 5ft of swell. Perfect for the dawn patrol.
Later, on Thursday the 17th morning, a glassy north wind and a 4ft southerly groundswell with a period of 11 seconds could offer some clean, lined-up sets. A good one for the points.
And then Friday the 18th morning looks promising again. A 4ft SSE groundswell, nice 12-second period, and a cross-off breeze from the NNE. Another very good window.
The end of the run on Monday the 21st morning is also clean with light cross-off winds and small, surfable 4ft easterly swell.
Be aware that between the 12th and 13th, we get a big pulse of swell – 10ft to 13ft from the southeast. The energy is massive (over 5000 on the Sunday morning), but the wind is onshore and choppy. With that much juice and the wrong wind, it's going to be a washing machine. For a river/jetty setup like this, that's a kite-surfing day, not a paddle-surfing one.
Overall, focus on the 7th morning, the 14th afternoon and the 18th morning for the cleanest, most fun waves.
Stay stoked, catch you in the water.
Rusty.
