The Lowdown
Alright folks, Rusty here. Gotta be straight with you – looking at the next 16 days for Octagon House, it’s a tough stretch. The whole period is a write-off for a proper paddle session. The swell is tiny, the wind is never fully offshore, and the whole setup is just messy.
For the first week, from Friday the 17th right through to the end of July, the swell is barely a ripple. We’re looking at combined wave energy values mostly in the single digits or low tens (40 - 7), which is nothing. The wind is either a cross-on breeze or a light cross-off, but the waves are just too small to do anything with. The water temperature is sitting at 85.8°, which is about normal for the time of year, but that's about the only thing that's average.
The latter part of the run into the first of August sees a bit more push, but it’s still no good. On the 31st of July, the swell bumps up to 4.3 ft from the SSE, and the energy ticks into the moderate zone (130), but the wind is a moderate cross-on or cross-shore, making it choppy and poor. The first of August sees the biggest swell of the window at 4.9 ft from the SSE, with energy at 187, but it’s still crossed-up and messy. Honestly, with that wind and the beach break setup, it looks more interesting for kite surfing than paddle surfing.
There are no standout days here. The whole 16-day window is a blank run, but for this area, it’s not unusual to see a stretch like this. Forecasts can change, but as it stands, leave the boards at home.
