The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks.
Gotta be straight with you, the outlook is a bit of a struggle. The finder didn’t put forward any strong recommendations, and when I look at the numbers, it’s a tough run. The forecast period kicks off on Thursday the 23rd of July and runs through to Friday the 7th of August, but there’s hardly a session that’s calling out to be had.
The only spot in the frame is Octagon House (Octagon). It’s a beginner-friendly, fairly consistent break that’s exposed to the swell. The water is sitting at 87°, which is a touch warmer than normal for this time of year. The overall pattern is a long stretch of small, weak swell with poor wind conditions. We’re looking at a solid two-week gap where the surf just isn’t worth chasing.
Let’s break it down. Through the first week, from the 23rd to the 30th of July, the swell is tiny—mostly 1 ft to 2 ft—with short periods of 4 to 6 seconds. The combined energy is weak, mostly in the teens and twenties (like 10 to 87 in the bracket). The wind is a constant problem: cross-off, onshore, or cross-onshore, with speeds from 15 to 25 mph. It’s going to be choppy and messy. There’s no standout here.
The second week doesn’t get much better. From the 31st of July through to the 7th of August, the swell picks up a hair, hitting around 3 ft to 4 ft, with periods still short at 5 to 7 seconds. The energy gets a little more lively, especially on the 5th of August, where it reaches 133 (moderate energy). But the wind is still a pain—mostly cross-onshore and onshore, often 20 to 25 mph. The conditions are described as poor across the board. The 5th of August morning has the biggest swell of the whole run at 4 ft, but it’s cross-onshore and choppy, so it’s not the clean, lined-up wave you’d want.
Honestly, if you’re a paddler, you’re better off giving this period a miss. The setup is more interesting for kite surfing than paddle surfing, given the consistent wind and the small, messy waves. For the rest of us, it’s a waiting game. Keep an eye on the forecasts—things can change, but right now, there’s nothing to get excited about.
