The Lowdown

Alright, surfers, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for pulling into anything decent at Navarro Rivermouth. We’ve got a lot of onshore wind and messy, lumpy conditions to wade through before we see any real potential, and even then, it’s going to be a tough call for most of us.

Right off the bat, from Saturday the 15th through to the 23rd, it’s a write-off for the most part. We’re looking at small, weak surf in the 3 ft to 4 ft range, with the energy barely getting going. The wind is sitting cross-onshore, and the wave quality is just poor – lumpy and uninviting. There’s nothing here worth paddling out for. Honestly, you’re better off finding something else to do.

Things start to pick up in size around Wednesday the 19th, with waves pushing to 6 ft, but the energy is still getting chopped by that moderate cross-onshore breeze. That trend continues into the weekend of the 23rd and 24th, with swell climbing to 8 ft, but it’s still coming with that cross-onshore wind and poor quality. The only slight glimmer in the whole stretch is on Monday morning the 24th, when a 7 ft NW swell shows up with lighter winds, earning a marginal call. But with a period of only 8 seconds, it’s still going to be a grovel, and not what I’d call a standout.

The bigger stuff starts to roll in during the last few days of the month. On the 25th and 26th, we’re seeing solid 8 ft to 8 ft surf. Morning sessions on the 25th and 26th hold a little more promise as the winds are lighter, but that cross-onshore angle is still going to put a wrinkle on things. This is when it starts to get serious, size-wise. By the afternoon of the 27th, we’ve got an 12 ft NW swell, and the table says the wind and tide are favorable, but it’s predicted to be too big for this break. That’s a session for experts only, and even then, it’s a gamble. The 28th brings a huge 13 ft NW swell, but it’s coming with a 20 km/h cross-onshore wind and the comment is just “poor surf conditions.” Too big, too messy, and not safe for most.

So, the long and short of it: the standout window, if you can call it that, is the 27th of August. It’s the one day where conditions align, but you’d better be a seasoned charger because that 12 ft swell is no joke. That’s the one to circle on the calendar if you have the skills and the nerve. It’s a week and a half out, so we’ll have to see how it shapes up, but it’s promising. The rest of the period is a lot of close-outs and blown-out waves. A spot like this, a rivermouth that’s already inconsistent, is going to be especially fickle with all this cross-onshore energy. Keep your expectations low and your patience high.

This is Rusty, signing off. Stay safe out there.

A general guide to surfing at Navarro 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 Navarro 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.
