The Lowdown
Alright, let’s get into it. Honestly, it’s a pretty grim outlook for the next 16 days here at Octagon House. We’ve got a long stretch with no real wave energy to speak of. The whole period is plagued by small, weak swell and poor conditions, so get ready for a blank run.
The first sign of any surf is on Wednesday the 30th of July, but don’t get excited. The swell is a tiny 2ft from the south with a short, weak period of 5 seconds. The combined energy is a measly 22 (weak energy), and the wind is a cross-onshore breeze. It’s just not worth paddling out. This poor quality continues day after day.
We finally get a brief moment of something better on the morning of Saturday the 1st of August. The swell is still only 2ft from the south, but the wind turns cross-offshore from the southwest, giving us clean conditions. The combined energy is still very low at 26 (weak energy). It’s ridable for a beginner, but the waves are gutless. The water temp is a touch warmer than normal at 87°, which is nice.
The best chance across the whole forecast comes on the morning of Monday the 3rd of August. The wind goes glassy, light offshore from the north-northwest with only 3 mph. The swell is 2ft from the south-southwest with a period of 4 seconds, but the combined energy jumps to 47 (weak energy). It’s still not big, but that glassy offshore wind will make the surface perfect. It’s the cleanest the waves will look all period. For a beginner, this is the standout window.
After that, it’s back to the same story. The morning of Sunday the 10th of August has the biggest swell of the run at 3ft from the south-southeast, with 5-second period and combined energy of 43 (weak energy). But the wind is cross-onshore, making it choppy. It’s not going to be pretty.
The very end of the forecast on the morning of Thursday the 13th of August offers a clean window with cross-offshore wind from the west-southwest, but the swell is only 1ft from the south-southwest. It’s barely a ripple.
Overall, this is a tough run. The break is fairly consistent, but the swell is just too small and the wind is often wrong. The only real standout is the morning of Monday the 3rd of August – that glassy offshore window gives you a chance for a fun, clean session on tiny waves. If you’re a beginner, that’s your moment. For anyone else, it’s a long wait for something that never really arrives.
