The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking for the next couple weeks. We’re looking at a slow start, but there’s a proper little window of fun shaping up further down the track if you’ve got the patience.
The first few days are pretty weak. Tuesday the 25th and Wednesday the 26th have tiny 1ft swells coming from the SW. The combined energy is way down in the dumps (88 to 65), so honestly, it’s not worth paddling out for anything more than a floating session. Thursday morning the 27th is a bit better with the energy bumping up to 91, but the swell is still just 1ft. It’s clean with a moderate offshore, but it’s a real struggle for any kind of ride.
We start to see a shift on Friday the 28th. The swell picks up to 2ft from the WSW and the energy kicks up to 326, but the wind switches to a cross-offshore, so it’s clean but the waves are still pretty poor. Saturday the 29th is the first day that starts to look interesting. The swell builds to 2ft in the morning, and by the afternoon it’s hitting 3ft from the WSW with a combined energy of 447. The wind is light and cross-offshore, so the conditions are clean. This is the first real glimmer of hope – a good sign for the weekend.
Sunday the 30th keeps the same 3ft swell, now coming from the SW, with a solid 372 energy in the morning and light offshore winds. It’s clean and surfable. That Saturday afternoon and Sunday are shaping up to be the best early windows.
Then we hit a bit of a lull again. Monday the 31st and Tuesday the 1st of September see the swell drop back to 2ft to 2ft with much lower energy. The wind is either moderate offshore or crosses onshore, making it messy. Wednesday the 2nd and Thursday the 3rd are pretty flat – 1ft to 2ft waves with very ordinary conditions.
Now for the real standout. Friday the 4th of September looks like the winner of the whole run. Potrero Grande (Ollie's Point) is going to fire. The swell jumps to 3ft in the morning and 3ft in the afternoon from the WSW, with a combined energy of 505 and 565 – that’s moderate to strong wave energy. The wind is light offshore in the morning and glassy by the afternoon. This is the kind of clean, lined-up SW groundswell that this point break loves. The period is 17 to 18 seconds, which is a proper long-period groundswell. At a point break like this, those long-period lines will wrap in beautifully. It won’t be too big for anyone, and with offshore/glassy conditions, it’ll be pristine. Saturday the 5th and Sunday the 6th also look good with similar 3ft swell and clean conditions, so it’s a solid weekend stretch. The water temp is about average for this time of year, so no surprises there.
After that, Monday the 7th and Tuesday the 8th fade back to 2ft waves with less energy, and by Wednesday the 9th we're back to tiny 1ft and strong winds. That run from the 4th to the 6th is the one to circle on the calendar.
Bottom line: Wait it out until Saturday the 29th for a taste, but the absolute best bet is Friday the 4th of September. That’s your golden window at Potrero Grande.
Rusty.
