The Lowdown
Alright, grab your board and listen up, it's Rusty here.
Right off the bat, I'm looking at the whole 16-day window and it's a tough one for Octagon House. The swell is just tiny, barely a ripple, for the entire first week and a half. We're looking at a solid block of nothing from the 19th of July right through until the 29th of July. That's a long, dry spell. The water is a warm 85° currently, which is about normal for this time of year, so at least you won't be cold while you're sitting there waiting for a wave that isn't coming.
For the first real sniff of anything rideable, you have to wait until the 29th of July. On Wednesday afternoon, the swell finally bumps up to 3ft from the SSE with a period of 6 seconds, and the combined energy hits 135 (moderate energy). It's a bit of a tease, though, because the wind is a moderate cross-onshore, making it choppy. It's still the best of a bad bunch by a long shot, but it's not exactly clean.
The following morning, Thursday the 30th, the swell drops back to 2ft from the S, and the energy is back down to 32. The wind is a gentle cross-onshore, so it's a bit cleaner but the swell is barely there.
The next day, Friday the 31st, the morning session has a 2ft S swell with a moderate cross-shore wind. It's messy, but at least there's some energy at 43. The afternoon gets worse with the wind switching to a stronger onshore.
Honestly, the standout - and I use that term loosely here - is the afternoon of the 29th of July. The swell is just over waist-high, but it's the only time the energy gets into the triple digits. Every other day, the energy is weak, mostly under 50. The wind is the main problem, it's almost always cross-on or cross-shore, never properly offshore. There's nothing here that's going to be clean, lined up, and worth a paddle. For a beginner spot, the swell never gets scary, but it also never gets good.
This is a tough outlook. The forecasts can change, but as it stands, I wouldn't waste the gas.
Rusty.
