The Lowdown
Alright folks, Rusty here. Let’s have a proper look at the coming swell window for Yo Yo's-The Wedge. This is a reef setup, advanced only, and it’s exposed to the southwest swell. The water’s sitting at 80°—right on the money for this time of year, no anomaly to speak of, so it’s lovely and warm.
The outlook kicks off Sunday morning, 30 August, with a clean 5 ft SW groundswell pushing in at a solid 13 seconds. It’s a bit crossed up on the wind early, but the energy is moderate (960). The pick of the day is Sunday afternoon: the wind shifts to a light cross-offshore breeze, the swell holds at 5 ft SW, and the conditions clean right up. It’s not massive, but it’s tidy and ridable.
Monday 31 August sees the swell dip a touch to 4 ft in the morning, but the period jumps to 18 seconds—proper long-period groundswell. The energy is building (1339), but with that super-long period, it’s going to be a bit more lined up and a bit more particular at the reef. The afternoon bumps up to 5 ft SW with the same 18-second period, and wave energy climbs (1795). Moderate cross-off wind keeps it clean. This is a standout for the first week: good size, excellent period, clean conditions.
Tuesday 1 September gets a bit heftier—7 ft SW in the morning and afternoon, still with a long period of 17-18 seconds. The energy is strong (2851). But the wind is pushing 16 mph from the SE, cross-off, so it’s clean but a little blustery. This is solid expert territory.
The run from Wednesday 2 September through to Friday 4 September stays in the 4 ft to 7 ft range, all SW swell, with periods dropping from 17 seconds down to 14. Winds remain cross-offshore, but the speed picks up to 19 mph at times, which will put a bit of bump on the face. Energy stays moderate to strong. Not the cleanest, but there’s always something to surf.
Saturday 5 September is a bit of a write-off in the morning—cross wind, cross-chop, 6 ft SSW. The afternoon cleans up with cross-off wind and the energy jumps back up (1403), but the quality is marginal.
Now, here’s where it gets interesting. Sunday 6 September through to Monday 7 September delivers a solid run of SSW swell. Sunday morning has 5 ft at 18 seconds (2718 energy), and Sunday afternoon pumps up to 7 ft at 16 seconds (2930 energy). That’s big, clean, powerful surf. But the wind is up around 16 mph, cross-off, so it’s a bit on the windy side for a pure glassy session. Still, the energy is strong.
The real standout of the entire forecast period is Wednesday 9 September. Morning sees 8 ft SSW at 17 seconds, with energy at 5017—very strong. The wind is a moderate 12 mph cross, so there’s a bit of cross-chop, but the afternoon is where it’s at: 10 ft SSW, 17 seconds, cross-off wind at 16 mph, and the energy is huge (4513). That’s big, powerful, expert-only reef surf. If you’re good enough, this is the day.
Thursday 10 September drops back to 7 ft in the morning, 7 ft in the afternoon, with 15-second period and strong cross-off wind. Still serious, but a step down.
The second week settles into a rhythm of 5 ft to 8 ft SW swell, with periods between 15 and 18 seconds. The pick of the second week is Sunday 13 September: 7 ft SW at 18 seconds in the morning (3985 energy), building to 8 ft SW at 17 seconds in the afternoon (3668 energy). Clean cross-off wind. That’s a proper session.
Look, overall, this is a solid run for Yo Yo's-The Wedge. The standout days are Monday 31 August afternoon for the clean, long-period groundswell, and Wednesday 9 September afternoon for the raw power and size. The water’s warm, the winds are mostly favourable, but it’s advanced-only territory. Don’t take a beginner out here.
Rusty.
