The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our stretch of coast. First up, the water temp is sitting at 87°, which is a touch warmer than normal for this time of year. That’s a nice little bonus.
Right, I’ll be straight with you – the next 16 days are a real struggle. There’s a massive gap right from the start. The first recommendation doesn’t come until Friday the 21st of August, and even then, it’s not good. We’re looking at a long, dry spell with no decent surf on offer until at least the 5th of September. That’s a solid two weeks of flat or poor conditions.
We’ve only got one spot in the mix, and that’s Octagon House. It’s a beginner-friendly, fairly consistent break that’s exposed to the swell. The problem is, the swell is tiny and the wind is a mess. The entire 16-day window is filled with poor surf conditions. The swell is coming from the S and SSE, but it’s barely scraping 3 ft at its best, and the period is a short, weak 4 to 6 seconds. The combined energy is well below 100 (45 is the strongest we see), which is just weak, weak energy.
The winds are a nightmare. For most of the period, it’s cross-on or onshore from the S, SSE, or SE, blowing at 9 to 16 mph, making everything choppy. There are a few morning windows with lighter cross-shore winds, like on the 22nd and 25th, where it’s a bit cleaner, but the swell is still laughably small (2 ft to 2 ft). It’s a tease.
Saturday the 5th of September morning is the only faint glimmer. We’ve got a light SW breeze (6 mph) creating a light cross-shore, with a swell of 3 ft from the SE at 6 seconds. The combined energy hits 45, which is still weak, but it’s the best it’s gonna get. The afternoon then gets ruined by onshore winds again.
Honestly, for the whole run, there’s nothing to get excited about. The swell is too small, the period is too short, and the wind is mostly rubbish. For a beginner, the tiny waves might be okay, but for anyone else, it’s a hard pass. The setup here is more interesting for a kite surfer than a paddle surfer on most days.
Keep the board in the car, but don’t hold your breath. Forecasts can change, but this run looks stubborn.
Rusty.
