The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Right and Left Side.

Right now, it’s a bit of a slow start. The first week or so is pretty much a write-off, with nothing but small, weak, and messy conditions. The swell is tiny, mostly around 1ft to 1ft from the ENE, and the energy is barely registering (26). The wind is mostly cross or onshore, and even when it goes offshore, the swell is just too small to do anything with. There’s a gap from the start all the way through to the end of July where I wouldn’t bother paddling out. It’s flat and frustrating.

Finally, we get a glimmer of hope on Sunday, August 2nd. The morning starts to show a little life with 2ft of ENE swell, and the energy starts to climb (173). The wind goes glassy, with the afternoon turning dead calm and glassy. The swell period jumps to 14 seconds, which is proper groundswell, and the energy jumps to 298. It’s not huge, but it’s clean and rideable.

Now, the real standout is Monday, August 3rd. The morning brings a clean 5ft of ENE swell, period still a solid 14 seconds, and the energy is pumping (1000). The wind is glassy, and conditions are prime for experienced surfers. This is the first day that’s worth getting excited about. The water temp is about average for the time of year, so no surprises there.

But the absolute best session on offer is Tuesday, August 4th, in the morning. We’ve got 5ft of NE swell, a very long 15-second period, and the energy is massive (1257). The wind is offshore from the SSE, making for clean, groomed faces. This is a proper groundswell, and it’s going to work well here. For a reef break, that long period means the waves will have real shape and power. It’s a bit much for beginners at over 5ft, but for the experienced crew, this is the one to circle.

The rest of the first week of August follows a similar pattern, with solid 5ft to 6ft of swell from the NNE, but the afternoon winds tend to get a little cross-onshore, so make sure you’re on the morning sessions. The mornings are consistently glassy or offshore, with the energy staying strong (over 1200).

Thursday, August 7th, is another big one. The afternoon brings a 7ft WNW swell, dead calm and glassy, with energy rocking (2006). That’s expert territory, but for those who can handle it, it’s going to be epic.

Then, on Saturday, August 8th, the morning offers up a 8ft WNW swell, glassy calm, with energy way up at 2758. That’s a serious swell, and it’s only for experts. The direction is a bit different from the optimum, but when it’s that clean and that big, you don’t complain.

So, to sum it up: the first week is a bust. The real action starts on Sunday, August 2nd, and the standout day is Tuesday, August 4th, with that clean, offshore, long-period groundswell. If you can only pick one session, that’s your morning.

Rusty.
