Rincon - Rivermouth Surf Forecast and Surf Report

G’day, Rusty here. Look, this forecast window for the region is a real mixed bag. We’ve got a run of small, clean waves coming through, but the standout sessions are the afternoons where a light cross-offshore breeze cleans things right up. The first week looks the most promising, with a few afternoons that’ll have you smiling, then it tapers off into a long, quiet spell. The water is sitting at a very unusual 71°F – that’s much warmer than normal for this time of year, so you might be in a spring suit or even a shorty.

We kick off on Friday the 28th and Saturday the 29th with small swell, around 2ft to 3ft from the SSW. The mornings are a bit messy with a cross-shore wind, but Saturday afternoon is the first real highlight. The wind goes light cross-offshore, the waves clean up to about 3ft from the SSW with a period of 16 seconds – that’s a long-period groundswell, which Rincon - Rivermouth (a point break) will love, giving it shape and power. Energy is moderate at 321. This is the best on offer for the first few days.

Sunday the 30th afternoon is solid again, with clean 2ft SSW swell and that light cross-off breeze. Energy drops to 301 but still fun. Monday the 31st and Tuesday the 1st see the swell fade to 1ft. The afternoons are clean but tiny – surfable but very ordinary.

Then we get a shout for Thursday the 3rd afternoon. The swell bumps back up to 3ft from the SSW, period 12 seconds, with that beautiful cross-offshore wind again. Energy hits 352 – this is one of the better windows, offering clean, rideable waves at the rivermouth. Friday the 4th and Saturday the 5th afternoons are also good, with 2ft to 3ft SSW swell and clean conditions. Energy is moderate in the 400 range, making for some fun, lined-up waves.

From Sunday the 6th onward, the swell slowly fades. The 6th afternoon is still clean with 2ft, but by Monday the 7th the energy drops to 125 and we’re into a long stretch of very small, ordinary surf. Tuesday the 8th through to Saturday the 12th September is a real lull. The swell sits between 1ft and 2ft, with energy below 200 most days. There’s no punch, no power. A few afternoons stay clean but it’s barely worth paddling out for.

The one bright spot in the second week is Thursday the 10th morning. A clean 2ft SW swell with a period of 17 seconds (very long groundswell) and light cross-offshore wind. Energy is 207. For a point break like Rincon - Rivermouth, that long period should wrap in nicely and give a few decent, lined-up runners. It’s the last real stand-out before everything fades away.

Overall, your best surf this whole window is Saturday afternoon the 29th, and then Thursday afternoon the 3rd of September. Both have clean conditions, moderate swell energy, and that classic rivermouth shape. Don’t hold your breath for the second week – it’s mostly flat and ordinary.

Rusty.
