The Lowdown
Grab a coffee and listen up. It's a grim picture here, folks. For Octagon House, it’s a long, tough stretch ahead. Honestly, for the first week plus, there’s barely a ripple worth paddling for. We’re talking tiny, weak, choppy slop day after day. The water is about average for this time of year, nothing wild there.
From Thursday the 16th right through to Monday morning the 27th, it’s almost all poor surf with combined swell energy barely ticking over, mostly below 50 (weak). The winds are almost always onshore or cross-onshore, messing up what little bump there is. There are a few moments of clean, cross-offshore glass on the 20th and 22nd, but the swell is so tiny (0.3 ft to 0.7 ft) you wouldn’t even get wet. It’s a brutal stretch with no real rideable waves.
The first sign of anything with a bit of push comes around Monday the 27th morning. The swell ticks up to 3 ft from the S, but with a short period of 5 seconds and a moderate cross-shore wind, it’s still going to be weak and messy with a combined energy of 52 (weak). Not something to get excited about.
The one true standout—and I use the term loosely—arrives on Friday the 31st of July. That morning we get a bit more size, 4 ft from the SE with a period of 8 seconds. The combined energy finally hits three digits at 176 (moderate wave energy). But here’s the kicker: it comes with a risk of thunderstorms and a moderate cross-onshore wind from the S at 12 mph. It’s the best on offer in this entire 16-day window, but it’s going to be choppy and bumpy. This break is exposed to the SE, so that direction is right on it, but the wind angle will spoil the surface. It’s a fairly consistent spot, but honestly, the whole month looks more interesting for a kite surfer than a paddle surfer.
So, to sum it up: you’re waiting until the end of July for the only real pulse of wave energy, and even then, the conditions will be rough. It’s a long dry spell. Keep an eye on the forecast, because it has to get better than this.
