The Lowdown

Alright folks, Rusty here. Let's have a look at what’s cooking at the Navarro Rivermouth over the next couple of weeks.

The short story? It’s a tough stretch ahead. This spot is a bit of a gamble anyway, being an inconsistent rivermouth wave that needs the right alignment, and for the next week, it just doesn’t come together. We're looking at a solid gap here, with nothing really worth paddling out for until the very end of the window. The water is sitting around 55°, which is a bit colder than normal for this time of year, so factor that in if you’re planning a session.

The week kicks off with some size, but it's not clean. From Monday the 10th of August through the weekend, we’ve got a mix of 8ft down to 3ft NW swell, but the wind is a persistent bummer. It’s mostly a light cross-onshore breeze, which combined with a short period (7 to 9 seconds), just makes for chop and poor conditions. The energy is there, with moderate readings up to 926, but it’s all messy. Don't get too excited about the bigger days on Wednesday the 12th—that 8ft swell with 1665 energy is accompanied by a cross-onshore wind of 9 mph, making it a choppy and poor experience, and that size is getting into expert-only territory on a river mouth.

Things drop off significantly after that. From Saturday the 16th through to nearly the end of the 16-day window, we’re in a dry spell. Swell heights are below 3ft, wind stays mediocre, and most of those days have a score of zero. It’s just flat and poor. There are a couple of long-period pulses on the 19th and 23rd (from the WNW and SW) with periods of 12 and 16 seconds, but the swell is too weak (under 3ft) to do anything with those long lines.

The only faint glimmer comes right at the tail end. On Monday the 25th of August, the swell starts to pick up again. We’re looking at 7ft of NW swell with a moderate combined energy of 806, but the wind is still cross-onshore at 9 mph. The forecast is marginal at best, and it’s still a week and a half out, so keep your fingers crossed that the wind cleans up. Until then, I’d save the petrol. This is a patch where forecasts can change, but right now, there’s nothing to rush for.

Rusty.

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.

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.
