The Lowdown
Alright folks, Rusty here. We’ve got a bit of a mixed bag coming up, so let’s cut through the chatter and get to what matters.
The first week is a tough one. The swell is there, but it’s a battle with the wind across most of the period. The real standout window looks to be around the end of the month and into the first day of August, where we finally see a bump in size and better conditions.
Right now, for Wednesday the 22nd and Thursday the 23rd, it’s mostly cross-onshore winds making a mess of things. The swell is small, around 3ft to 4ft from the SSW and S, but the wind is just ruining it. The combined wave energy is moderate (553 to 642), but with that cross-on breeze, it’s choppy and pretty poor. Friday the 24th is no better, with tiny 2ft swell and a cross-on wind. The energy drops off a cliff to 299 in the afternoon. This is not the time to paddle out.
The weekend doesn’t offer much relief. Saturday the 25th and Sunday the 26th stay in that 3ft to 3ft range, with the wind swinging around to the south, making it choppy again. The energy is moderate (around 751 to 909), but the surf quality is poor. You’re better off waiting.
Now, Monday the 27th and Tuesday the 28th start to show a little promise. The wind finally goes light and offshore from the SSW and SW. The swell picks up slightly to 4ft to 4ft, still from the SSW. The energy jumps into the strong range (around 1035 to 1093). The conditions are described as marginal, but with that light offshore wind, it’s a huge step up from what we’ve seen. It’s not perfect, but it’s the best we’ve had so far.
The real highlight, though, is shaping up for Friday the 31st of July through Saturday the 1st of August. On Friday the 31st, the swell is building. The morning is 3ft from the S, but the afternoon jumps to 5ft from the S, with a period of 14 seconds. That’s a nice groundswell. The wind is light and offshore in the morning, turning light cross-on in the afternoon. The energy is strong, hitting 1077. Then Saturday the 1st of August, the swell peaks at 6ft from the S. The wind is light cross-onshore, but the energy is pumping hard at 1200. This is the swell to keep an eye on. It’s getting a bit big for beginners, but for the experienced crew, this is the best window of the whole forecast.
After that, things fade out quickly. Sunday the 2nd drops to 4ft, and by Monday the 3rd we’re looking at tiny 2ft swell and poor conditions. The rest of the first week of August is flat and windy.
So, for the standout, I’m pointing you straight at Trestles (Lowers). The best surf will be on Friday the 31st of July, with that 5ft S swell and light offshore winds, and Saturday the 1st of August with the 6ft S swell. It’s a beach and reef setup, very consistent, and it’s exposed to the SW swell, which is a good match for the direction we’re seeing. Just remember, it’s always crowded here, so get there early.
Rusty.
