The Lowdown

G’day, it’s Rusty here. We’ve got a pretty quiet stretch ahead at Rincon - Rivermouth. The water’s sitting at 69°, which is much warmer than usual for this time of year – a nice surprise if you’re paddling out in a spring suit.

The first week is mostly small and ordinary. Wednesday the 19th sees a tiny 2ft SSW groundswell with a long 15-second period, but the morning is cross-shore and the afternoon goes clean with light WSW cross-off breezes. Combined energy is weak (237 in the morning, 188 in the afternoon). It’s surfable, but only just. Thursday the 20th is similar – 2ft SSW, 14 seconds, clean in the afternoon but still tiny. Friday the 21st drops even smaller to 1ft, and the energy bottoms out around 106. Saturday the 22nd has a brief bump to 2ft W swell, but with a short 10-second period, it’s not doing much. Sunday the 23rd through to Thursday the 28th is a long run of 1.0ft to 1ft swells, mostly clean but with combined energy rarely cracking 200. It’s pretty ordinary.

Now, here’s the standout. Saturday the 29th of August morning, things finally wake up. We’ve got 3ft SSW groundswell with an 18-second period and combined energy jumping to 423 – that’s moderate and the most energy we’ve seen all outlook. Winds are light SW, cross-off, and clean. This is the best on offer for those who like a long-period point break. Sunday the 30th morning holds similar energy at 3ft SSW, 16 seconds, and 479 combined energy, also clean. It’s a promising window, but we’re over a week out, so keep an eye on it – long-range forecasts can shift.

After that, from Sunday afternoon the 30th through to Thursday the 3rd of September, it fades back into marginal or poor conditions with small swells and light cross-shore winds. The energy drops off again into the double digits.

So, the best bet is definitely Saturday the 29th and Sunday the 30th mornings at Rincon - Rivermouth. It’s a fairly consistent point break exposed to WNW, and with the long-period SSW groundswell, it should wrap in nicely. Crowds are often here, so get in early. Not a standout for beginners with the 3ft – 3ft range, but it’s solid for intermediates.

Stay stoked,
Rusty

A general guide to surfing at Rincon - Rivermouth can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Rincon - Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
