The Lowdown
Righto, Rusty here. Let’s have a look at the next couple of weeks, and let me tell you, it’s a bit of a slow burner with one hell of a payoff if you’re patient.
We start off with a few fun, clean days on the cards. For the first part of the week, the waves are small but the conditions are going to be seriously good. We’re looking at clean, glassy surfaces with light airs and the water is running a touch warmer than usual for this time of year, which is a nice bonus.
Monday the 10th kicks off with some chest-high lines, around 4ft to 4ft, out of the southwest with a solid 14 to 16 second period. The energy is moderate (596 to 923), but it’s going to look like a million bucks with no wind on it. This is your classic small-wave window where you can get a few fun ones without any drama.
Tuesday the 11th is much the same story, with 4ft SW swell and 14-second period. Another glassy morning, and the afternoon turns it on too. This is a great chance to get your log out and just paddle around. The energy is still moderate (610 to 769), so don't expect any power, but it’ll be clean.
Wednesday the 12th gets a bit messier. The swell bumps up slightly to 4ft from the southwest, but a light cross-onshore breeze puts a bit of chop on it. It’s not terrible, but the magic is gone. Thursday the 13th cleans right back up with a light cross-offshore in the morning and dead calm in the afternoon, but the swell drops a little to 4ft, making it a small, clean day for the mellow crew.
Now, here’s where things start to get interesting. Friday the 14th morning, the swell jumps to 5ft from the southwest, with a 13-second period and the energy is ramping up (1087). It’s still glassy, and this starts to feel like proper surf. But the real standout, the one you should be circling on the calendar, is Saturday the 15th.
Saturday morning starts with 5ft of clean SSW groundswell and dead calm conditions, but it’s the afternoon where it gets special. The swell pushes up to 7ft, still out of the SSW, with an 18-second period. The energy is significant (4337), and it’s dead glassy. This is proper, powerful reef surf. This is the pick of the week for sure.
Sunday the 16th keeps the good times rolling. We’ve got 7ft to 7ft of that long-period SSW groundswell, with a touch of light air in the morning and glass in the afternoon. The energy is still strong (2414 to 3036). It’s going to be big, clean and powerful. Just be aware, this size is for experienced surfers only.
After that, things back right off again. Monday the 17th drops back down to around 4ft, and the conditions aren't as clean. We get a bit of a mixed bag, but there’s still some fun to be had on the glassy afternoon. Tuesday and Wednesday the 18th and 19th see the swell drop further to around 3ft to 3ft. Consistency is there, but we're back to small, clean surf.
The second week stays pretty quiet. From the 20th through to the 23rd, we’re looking at small, clean waves in the 2ft to 3ft range. Not much energy to get excited about, just long-period background pulses. Honestly, this is the kind of stretch where you don't need to rush out.
However, there’s one more promising blip on the long-range radar. Around Monday the 24th and Tuesday the 25th, a new pulse of S swell looks to push in. It’s expected to be another solid one, with the swell building to 6ft to 7ft on the Monday, and while the winds look a bit iffy at first, Tuesday the 25th afternoon looks like it could clean right up again with 6ft and glassy conditions. That's a promising sign for the end of the window, but it's a long way out, so don't book your flights just yet.
Overall, the standout window is Saturday the 15th through Sunday the 16th. That’s the one with the size, the power, and the glass. Don't sleep on it.
Rusty, signing off.
