The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks.
Well, I gotta be straight with you – this is a tough one. We’re looking at a seriously long stretch of flat, poor surf conditions. The only spot that’s even in the conversation is Laniakea Reef and Holtons, but honestly, it’s a grim picture for a while.
The first 7 days are basically a write-off. From Tuesday the 11th right through to Monday the 17th, we’ve got nothing but tiny, weak swell. We’re talking waves around 0.7ft to 1.0ft, with combined energy levels barely hitting double digits (19 to 40). The water temp is sitting at a pretty normal 80°F for this time of year, but you won’t need a wetsuit because you won’t be surfing. The wind is cross-offshore from the east, which is a decent direction for this break, but there’s just no power in the water to make anything of it. It’s a real bummer.
Now, we finally get a little flicker of hope on Tuesday the 18th. The morning still looks poor, but by Tuesday afternoon the combined energy jumps to 209 (moderate), with a 3ft swell from the NE. The period is 8 seconds, so it’s a short-period windswell, but it’s the biggest we’ve seen all forecast. The wind is a gentle cross-offshore breeze from the east at 9 mph, which would keep things clean. This is the only window that might be worth a look, but it’s still a marginal call. Don’t get your hopes too high.
After that brief tease, it’s right back to the doldrums. From Wednesday the 19th through to Wednesday the 26th, we’re back to tiny ripples. The swell drops to 0.7ft to 2ft, with combined energy mostly under 100 (weak). The wind stays cross-offshore, but it’s like polishing a turd – there’s just nothing to ride.
Look, this is a classic late-summer lull for this area. It’s a blank run that can happen. There’s no standout day here, not even close. The only tiny window to even consider is Tuesday the 18th afternoon at Laniakea Reef and Holtons, but even that’s a stretch. Pack the board away for a bit, or take up fishing.
Rusty.
