The Lowdown

Alright, Rusty here. Let's have a look at what's on offer for this stretch of coast.

Right off the bat, I gotta be straight with you: this run looks pretty bleak for paddle surfing. For the next ten days or so, it’s all cross-onshore wind and messy, choppy conditions. There’s plenty of swell showing up, but the wind just has it all blown out. The first real chance at something clean doesn’t roll around until Tuesday the 4th of August.

The one spot on the menu is Navarro Rivermouth. It’s an inconsistent river mouth break that needs everything to line up. For the early part of the outlook, from Tuesday the 28th of July right through to the 3rd of August, it's a no-go with "poor surf conditions" stamped all over it. We're seeing a moderate wave energy (around 494-569) on Tuesday the 28th and Wednesday the 29th, with swell heights around 8 ft to 8 ft and a short, weak period of just 7-8 seconds. This is expert-only size, but with a fresh 16 mph cross-onshore wind, it’s just a washing machine. By the weekend of the 1st and 2nd of August, the swell really jacks up, hitting 12 ft to 13 ft with a combined energy reading well over 1500, but it’s coupled with even stronger wind and a "lumpy" description. That’s kite-surfing territory, not for a paddler.

Now, here’s the one true standout. Look at Tuesday the 4th of August. The wind drops right out to a glassy 3 mph from the WNW in the afternoon. The swell settles to a manageable 6 ft from the NW with a combined energy of 476. The forecast says "expect good surf conditions." That’s your window. The water temp is sitting at 57°F, which is about average for this time of year so don't expect a warm one.

If you miss that, there’s a smaller repeat on Wednesday the 5th of August in the afternoon. Again, glassy wind at 3 mph from the west, with a slightly smaller 5 ft NW swell and 369 energy. It’s a marginal call, but with those clean, glassy conditions, it might be worth a look if you're desperate for a few clean ones.

After that, it's a long stretch of poor conditions with consistent cross-onshore winds and bumpy surf through to the end of the forecast period on the 12th. The swell stays on the small side with some moderate energy spikes, but the wind never cooperates again.

So to sum it up: if you’re gonna paddle, your only real shot is the afternoon of Tuesday the 4th of August, with a backup on the 5th. Everything else is blown out or for the kite crew. Keep an eye on the forecasts, though—it can always flip.

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. 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.
