The Lowdown
Alright, Rusty here. Let's take a look at what's on offer for the local stretch.
Honestly, the next couple of weeks are looking pretty flat and uninspiring for a proper paddle session. We're looking at a long stretch of small, weak surf with very little push behind it. The water temp is sitting at 76°, which is right about average for this time of year, so not much to complain about there, but the waves just aren't cooperating.
The first real sniff of anything worth mentioning doesn't come around until Monday the 17th of August. Early that morning, we see a new pulse of long-period groundswell, 13 seconds, coming from the SE. That's a good sign for energy, but the swell height is only about 1 foot, and it's all locked up in a cross-shore wind, so it's messy. The real highlight, and the only standout in this whole forecast, is Monday afternoon. The wind drops to glassy, and we get a cleaner 1-foot wave from the SE with a solid 13-second period. The combined energy is moderate at 77. It's tiny, but for a log or a longboard, that glassy window with that long-period groundswell could offer up a few clean, fun lines. It's the best on offer, but it's a very small window of opportunity.
After that, the rest of the week slides back into poor conditions with small, short-period windswell and onshore winds. We do see a brief spike on Thursday the 20th of August. The morning has a clean 2-foot SE swell with a gentle offshore wind from the W, and the combined energy jumps to 93. The afternoon pushes a bit more size to 3 feet from the SE, with energy hitting 128. That's the most powerful window of the entire forecast. The winds are a bit more cross-off that afternoon, but it's still clean. For a beginner-friendly spot, this is the most surfable it's going to get, but it's still not what you'd call pumping.
The run from the 7th to the 17th is a real dead zone, with nothing but tiny, weak waves and poor conditions. Then, the 17th afternoon offers a small, clean glimmer of hope, and the 20th gives us the best size and energy of the whole outlook. It's a tough call, but that's the reality of it.
Rusty, signing off.
