The Lowdown
Alright, let’s get into it.
Honestly, the next couple of weeks are looking pretty grim for a proper surf. We’ve got a long stretch of small, weak, and wind-affected waves ahead. The swell energy is just non-existent for the most part, with values in the low double digits or even single digits for a lot of the period. We’re talking about a real lull.
The first week is basically a write-off. From Saturday the 8th through to Friday the 14th, we are looking at nothing but knee-high slop and onshore breeze. There’s a bit of a pulse on the Saturday morning, but it’s coming in at 3ft from the ENE with a cross-on SE wind, making it choppy and messy. The energy is weak, with a combined value of 103. Don’t bother. The rest of the week is even smaller, with the swell dropping to 0.3-0.6ft. There’s a glassy window early Wednesday morning, but there’s just no swell to make it worthwhile. It’s a classic summer flat spell.
The following week sees a couple of little bumps, but nothing that would get you excited. Saturday the 15th shows a slight increase to 3ft from the SE, but the wind is up to 15 mph from the SE, making it a choppy mess. The jetty will be a crumbly, cross-onshore mess, way more interesting for the kite crew than for us. The energy is still weak, sitting around 31-34.
We’re looking at a long gap with no real options until we get to the back half of the month. The morning of Sunday the 23rd is the only thing that even gets close to a “pop.” We finally see a cleaner window with a light W wind and glassy conditions, and the swell pushes up to 3ft from the NE. The energy jumps to 81, which is the best we’ve seen in this whole stretch. The period is 9 seconds, so it’s a bit of a short-period windswell, but it’s the only thing on offer. It’s still far from perfect, and the afternoon goes back to the poor cross-on junk. But for a guy who’s desperate, it’s the only wave in town.
So, keep your expectations low. The jetty is a sharky, ribbed-bottom spot that needs a decent push of swell to work, and it’s just not getting it. The water temp is sitting at 85°, which is about normal for this time of year, so at least it’s warm while you’re sitting there wondering where the waves went. This is a classic summer flat spell for the area. Hang loose, and hopefully, the forecasts change.
