The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the next stretch.

We’re starting with a bit of a wait. The first few days are a write-off, with a massive, messy swell from the south and howling cross-shore winds. Tuesday the 4th through Wednesday the 5th are just plain ugly, with the wave energy up around 3807 to 9824, but it’s all lumpy, choppy, and crossed up. Not worth a second look.

Things start to clean up a bit on Thursday the 6th, but the conditions are still marginal. The morning offers a 10ft south swell at 11 seconds with a cross-offshore breeze, but it’s still a bit of a battle. The real first glimmer of hope comes on Friday morning the 7th. We’ve got a light NW offshore wind, clean lines, and a 4ft SE swell. The wave energy is a modest 615, but it’s clean. The standout for the early part of the week is Saturday morning the 8th. A gentle offshore from the NW, clean conditions, and a 4ft SE swell with a 13-second period. The water temp is sitting at 56°, which is about 1° cooler than average for this time of year, so nothing wild, just a typical chilly winter dip. This morning is the pick of the first week: clean, organised, and fun.

Sunday the 9th stays clean with a smaller 3ft to 3ft swell, but it’s the kind of day you take the log out. The consistency is good, but the energy is low. Monday the 10th we get a weird one – a short-period 6-second south swell in the afternoon that’s just trash. Then Tuesday the 11th morning comes back with a clean 4ft SSE swell and an offshore WNW breeze. That’s nice.

Now, looking further ahead, the surf builds again. The big news is the swell arriving on Saturday the 15th. That morning, we’ve got a clean 7ft ESE swell with light NW winds. The wave energy is 887, which is solid. But the real standout of the whole forecast is Sunday morning the 16th. This one is for the experienced crew only. We’re talking an 12ft ESE swell, clean offshore NW wind, and wave energy of 4178. This is proper, powerful groundswell. The period is 10 seconds, so it’s got some punch, but it’s not a super-long period that might make it weird. The wind is perfect, the swell is big, and the break is exposed. It’s going to be downright heavy. This is the best session on offer, but only if you’ve got the chops. Expect crowds at Stockroute, as it’s a spot that sees people.

Monday the 17th keeps the big energy going, with 10ft to 12ft ESE swells and clean conditions in the morning, again for the experienced surfers. Tuesday the 18th is still solid with 10ft to 8ft swells, and the wind stays favourable. The energy drops off a bit by Wednesday the 19th, with a 7ft ESE swell, but the wind picks up from the WNW, so it’s still clean-ish.

So, to wrap it up: the first few days are a total washout. The best window is the morning of Saturday the 8th for a clean, fun, smaller day. Then, the absolute standout is Sunday morning the 16th for the big, clean, powerful stuff. That’s the one you circle on the calendar.

Rusty.
