The Lowdown
Alright, let’s talk about what the Navarro Rivermouth is cooking up over the next couple of weeks. It’s a river mouth spot that’s fairly open to the north-west, but it doesn’t break all that often, and when it does, you can expect there’ll be a few of you out.
First few days are rough. Choppy, cross-onshore wind and dirty water. Water temp is running about 56°, a bit chillier than what we normally see this time of year. You’ll be glad for the rubber.
The first real chance to score is the morning of Thursday, September 3rd. There’s a 3ft south-west swell, super long period at 19 seconds, and the wind is dead glassy. For a river mouth, that long-period groundswell can sometimes get a bit straight, but with zero wind it should be clean and lined up. Energy is solid (831), and you’ll have plenty of time between sets. It’s a beginner wave at heart, and with the size small and conditions pristine, this is your best early window.
Then we go through a long, average patch. Windy, lumpy, cross-onshore all the way to the 9th of September. That morning has a decent 6ft north-west swell, 12-second period, and strong energy (1074), but it’s still bumpy. The real highlight of the whole run is the afternoon of Wednesday, September 9th. Swell stays up at 6ft from the north-west, period still 12 seconds, energy is very strong (1013), and the wind goes glassy again. That’s a rare combo – powerful, clean waves at the rivermouth. It’s on the bigger side, so best left to surfers with some skill, but the conditions will be mint.
After that, it drops off pretty quick. Some smaller days with cross-shore wind, not much to write home about. For a break that’s inconsistent, this is a case of picking your moment – Thursday the 3rd morning and Wednesday the 9th afternoon are your two golden windows.
Stay salty,

Information about the Navarro Rivermouth Surf forecast
The above surf forecast table for Navarro Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Navarro Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Navarro Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Navarro Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
