The Lowdown
Alright, let’s get into it. The surf over the next two weeks is gonna be a real mixed bag. We’ve got some clean swell lined up, but there’s a lot of waiting involved. Let’s break it down.
Right now, Monday the 10th kicks things off with some proper energy at Little Austi and Main Beach. We’re looking at a solid 7 ft swell from the ENE, with a period of 9 seconds – that’s a decent groundswell, but it’s gonna be a bit of a handful for the beginners. The combined swell energy is sitting at a moderate 676, so there’s plenty of push. The wind is a fresh offshore from the NNW at 19 mph, which will clean it up nicely. Water temp is 64°, which is pretty average for this time of year, nothing unusual. Afternoon holds similar size, but the wind swings NW and stays offshore. This is your best bet for the first few days, but be aware the tide might play games with the shape.
By Tuesday the 11th, the swell drops right off to 2 ft, and the wind goes cross-offshore. It’s clean, but there’s just not enough push. This flat spell stretches through Wednesday, Thursday, and Friday – those days are basically a write-off. You’ll be looking at ankle-to-knee high dribble with glassy conditions on Friday morning, but it’s not worth paddling out for.
Saturday the 15th brings a bit of life with a 3 ft short-period SSE swell (6 seconds), but the wind is cross-onshore and choppy. Not good. Sunday’s even smaller. This poor run continues right through to Tuesday the 18th, where we see a bit more size – 6 ft – but the wind is cross-onshore and the quality is poor.
Now, here’s where it gets interesting. Thursday the 20th is a standout. Morning glass-off with zero wind, a clean 4 ft ESE swell at 9 seconds, and a combined energy of 367 – moderate, but it’s the cleanest conditions we’ve seen in over a week. The wave comment says “expect good surf conditions,” and that’s what we like to hear. This is the one to aim for if you can get out early.
Friday the 21st morning is also clean with a slight offshore breeze and 4 ft ENE swell, but the afternoon gets messy with a moderate cross-shore. Saturday the 22nd morning is similar – clean, 4 ft, good energy – but again, the afternoon falls apart.
The real standout in the longer range is Monday the 24th. We’ve got 6 ft to 7 ft SSE swell at 8 seconds, but the wind is a gentle offshore from the NW, and the combined energy jumps to 903 – that’s strong, powerful surf. The wave comment says “expect very good surf conditions.” This is for experts only though – over 5 ft, and at 7 ft it’s big, powerful, and will be handling some serious punch. If you’re an experienced surfer, mark that date.
Tuesday the 25th holds size at 5 ft to 6 ft from the E, with a long 12-13 second period – that’s proper groundswell. The wind is light, but it’s cross-shore, so the shape might be a little wonky. Still, that energy is there (940), so it’s worth a look for the experienced crew.
Bottom line: the best windows are Thursday 20th morning for clean, manageable waves, and Monday 24th for a serious, powerful session. The rest of the time, you’ll be waiting. Hang in there.
