The Lowdown
G’day, Rusty here. Look, I’ll level with ya – the next 16 days at Rincon – Rivermouth are a real mixed bag. We’re looking at a long stretch of small, forgettable surf, with a couple of windows that might just save the summer. The water’s sitting at a toasty 70°, which is a solid 7° warmer than normal for this time of year, so that’s a real treat for the skin.
The first real glimmer of hope comes Saturday, August 8th. The morning’s a bit messy with a cross-onshore breeze, but the afternoon cleans right up. We’ll see a 2ft SSW swell with a period of 16 seconds – that’s a proper long-period groundswell, which at a point break like this is a good thing. The combined energy is moderate at 215, and with light offshore winds, it’ll be clean. This is your best bet in the first week, but for a Rivermouth, it’s still small.
We hit a bit of a lull after that, with a few days of poor conditions and cross-onshore winds. The standout in the whole forecast is Sunday, August 16th. The morning brings a 2ft SSW swell, 16-second period, and light cross-offshore winds. With a combined energy of 255 (moderate), conditions are labelled as “good.” This is about as good as it gets – small, clean, and workable for the intermediate crew. The 14th and 15th of August see bigger energy numbers (308 and 332) but the winds are cross-onshore, ruining the quality. If you’re an expert, those days might offer a challenge, but for the average punter, they’re a pass.
Overall, don’t expect any barrels. The swell stays under 3ft for the whole run, so it’s strictly a longboard or funboard game. The 16th of August morning is the pick of the crop. That’s the one to circle.
Rusty.
