The Lowdown
Imperial Units
Alright, Rusty here again, breakin’ it down in feet and degrees for those who think in inches.
Water temp is sitting at 71°F right now, and that’s a whopping 8°F warmer than usual for this time of year. You can ditch the rubber for a boardies session if you’ve got the gumption.
Right then. This afternoon, Monday August 31st, we’ve got a piddly 1ft SSW swell rolling in with a solid 13-second interval. Wind is light out of the WSW, which puts it cross-off at Rincon - Rivermouth. The combined energy is weak at 86, so it’s tiny, but glassy clean. It’ll be crowded – this spot always sees a crowd when it’s clean – but for a log or a fish, it’ll be good fun.
Tuesday the 1st and Wednesday the 2nd are dead. Cross winds and next to no energy (down to 67). Save the gas.
By Thursday the 3rd of September, there’s a pulse. The afternoon sees the swell push to 2ft from the SSW with an 18-second period. That’s proper groundswell. The combined energy hits 281 (moderate). Wind is light but cross, so it’s a bit bumpy, but there’s enough power to make a few waves interesting.
Friday the 4th of September is the standout. The morning is still building at 2ft with a 17-second period (energy 271), but by Friday afternoon, it’s 3ft from the SSW at 16 seconds, with a light WSW cross-off breeze. The combined energy climbs to 366 (moderate). It’ll be clean, well-shaped, and with that long period, the point will link up nicely. Not too big – perfect for intermediates.
Saturday the 5th afternoon is also solid – 2ft, cross-off wind, combined energy of 228. A nice little encore.
Sunday the 6th and Monday the 7th fade back into the doldrums – tiny 2ft waves, energy dropping below 170, and winds getting messy. Heavy rain rolls in Monday morning, but the point stays clean thanks to the offshore angle.
The second week, from September 8th onward, is a flat snooze. Swell sits at 1ft to 1ft, combined energy mostly under 100, with winds shifting onshore or cross. The only glimmer is Thursday the 10th afternoon – 2ft of SSW swell at 16 seconds, light cross-off wind, and combined energy of 206. Might give a few clean little corner waves if you’re keen.
The clear winner is Friday the 4th of September afternoon at Rincon - Rivermouth. Small but clean, long-period groundswell, light offshore wind. It’s the best we’ve got.
Rusty.
