The Lowdown
Alright, this is Rusty. Let's have a look at what's on the table for the next couple of weeks.
Honestly, mate, it's a pretty flat stretch for this area. We're looking at a solid 16-day run but the truth is, the surf is just not showing up. The first recommendation for a wave is on Monday, July 20th, but it's a tiny 0.3ft on a short period of 4 seconds from the SSW. The energy is barely registering (7). It's a poor surf condition, and it stays that way. There's a long gap of absolutely nothing worthwhile until the very end of the outlook.
The only real time to even consider it is around the very end of the forecast, from the 1st of August onwards. The swell picks up ever so slightly, but it's still struggling. On Sunday morning, August 2nd, we get a little bump with a 2ft swell from the S, but the period is still a short 5 seconds, and the combined energy is only moderate (34). The wind is cross-offshore from the WSW, so it could be clean. But it's still a tiny wave, and the energy is just not enough to get excited about. The following Monday morning, August 3rd, looks similar with a 2ft swell from the SSW, a 4-second period, and a cross-offshore wind from the WSW. It's clean, but again, it's barely a wave.
The main spot here is Octagon House. It's a beginner-friendly break, and it's fairly consistent, but there's just no swell to work with. The water temperature is about average for the time of year, nothing unusual. For the whole 16 days, the wave energy never gets out of the weak zone, with the highest reading being a moderate 58 on the 28th of July. That's not enough for a proper surf.
If you're desperate for a paddle, the 2nd and 3rd of August mornings are your best bet, but it's a real struggle. This is a classic blank run for this area; it happens. The forecasts can change, but as it stands, there's nothing to recommend.
Rusty.
