The Lowdown

Alright folks, Rusty here. Let’s get straight into it. Honestly, the outlook for Navarro Rivermouth over the next 16 days is a tough one. We’re looking at a long stretch of poor surf and tricky conditions, with very few windows worth paddling out for.

The first real chance to even think about a wave doesn’t come until Saturday morning, July 18th. Even then, it’s marginal. The swell is coming from the WNW at 3 ft, with a long period of 16 seconds, which is a proper groundswell. The energy is moderate, at 1099, but that long period can make a river mouth break a bit tricky, often running too straight. The wind is onshore, so it’s not going to be clean. The water temperature is 54°, which is a bit colder than normal for this time of year.

The only real standout, and I mean the only one worth a mention, is a very brief window on the afternoon of Friday, July 24th. The wind is glassy, which is a massive positive for a spot that usually runs cross-onshore. The swell is small at 2 ft from the NW with a period of 8 seconds, and the energy is weak at 69. It’s a tiny wave, but for a river mouth that’s inconsistent, that glassy surface will make it look a lot better than anything else in the window. Don’t expect much, but it’s the best of a bad bunch. Crowds are often a factor here, so on that one glassy afternoon, it might be busier than you’d hope for such small surf.

The rest of the period is dominated by windy, choppy cross-onshore conditions, with swell heights typically between 4 ft and 8 ft, but the wind is just ruining it. The period is short, mostly 6-8 seconds, with moderate energy readings. For a few days around July 16th-17th, the swell is bigger (over 8 ft) and combined energy hits four digits, but the wind is strong and cross-on, making it a total mess. That’s more of a kite-surfing setup than a paddling one.

The gap between the poor and marginal days is huge. Don’t hold your breath. It’s a rough run for this spot.

Rusty.

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.
