The Lowdown
G’day, Rusty here. Look, it’s a pretty quiet stretch ahead for the Rincon - Rivermouth area. We’re looking at a solid two-week run of small, mostly messy waves with a few windows where things tidy up. The first real chance of a surfable wave doesn’t show up until Wednesday afternoon, so don’t bother paddling out before then.
The standout period kicks off on Friday 18th September with the afternoon session. We’ve got a clean little 1ft swell rolling in from the SW, with a period of 19 seconds – that’s proper long-period groundswell, meaning better-shaped waves and more energy behind them, but at a point break like this, it’ll handle it just fine. The combined swell energy is sitting at 231 (moderate), and with those light cross-offshore winds from the WSW, the face is gonna be clean as a whistle. Crowds are likely here, so get out early if you can. Saturday 19th afternoon is the other gem – 2ft from the SW, 18 seconds, energy at 261 (moderate), and again those clean cross-off winds. It’s not big, but it’ll be fun on the right board.
The rest of the fortnight is a mix of mornings with cross or cross-onshore winds and afternoons that clean up but only deliver knee-high slop. The long-period swell (over 15 seconds) shows up a few times, but the size just isn’t there to make it exciting. The water temp is about average for this time of year, nothing unusual.
Hang in there – these flat spells don’t last forever. Rusty.
