The Lowdown

Alright folks, Rusty here. Let’s get straight into it for the Navarro Rivermouth zone.

Alright, I’ll be honest with you – the next couple of weeks are a tough watch for this spot. We’re looking at a real dry spell for quality waves. The first surf we can even talk about doesn’t show up until Monday the 14th, and even then it’s a struggle. For the next several days after that, the conditions are pretty grim, with a lot of cross-onshore wind and chop messing up the lines. The water temp is sitting at 57°, which is about 2° cooler than average for this time of year – nothing too wild, just a touch on the crisp side.

The first real standout – and I use that term loosely – comes on Wednesday the 16th afternoon. We get a brief window of glassy conditions with a light WSW breeze at 3 mph. Swell is 6 ft from the NW with a period of 9 seconds, and the combined energy is moderate at 454. The direction is close to the optimum NW, so it could actually shape up okay for a short while. This is the pick of the entire period. But keep in mind, this break is inconsistent and rarely offers a classic bank, so you’ll need to be lucky and ready to go when that window opens. Crowds are often an issue here too, so don’t expect to have it to yourself.

After that, it’s back to the grind. The rest of the week and into the next sees mostly cross-on winds and poor surf conditions. There’s a pulse of NW swell around Monday the 21st with heights pushing 7 ft to 7 ft, but it’s all cross-onshore and choppy, so it’s a mess. That’s more of a kite-surfing setup than a clean paddle session.

Further out, around Wednesday the 23rd, we see a shift to a longer-period NW swell (12 seconds), but it’s still cross-onshore and the quality isn’t there. The combined energy drops to moderate-low at 614. Nothing to get excited about. The last real mention is Sunday the 27th morning, with 5 ft NW swell and light cross-on winds, but it’s marginal at best.

Honestly, if you’re after clean, rideable waves, the only moment worth your time is that Wednesday afternoon glass-off. The rest is a lot of wind, chop, and frustration. For this area, a blank run like this is pretty normal, so don’t lose hope – forecasts can change.

Stay tuned, stay stoked.
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.
