The Lowdown
Alright, let’s talk Navarro Rivermouth. I’m Rusty, and I’ve been through this forecast more than once. It’s a rocky road for the next 16 days. This is a river mouth, inconsistent, and good for beginners, but the wind and conditions are fighting us most of the time.
The surf kicks off Monday, 13 July, with a 6ft NW swell, but the period is a short 8 seconds, and the wind is cross-on at 12 mph. The water is 54°, a bit colder than usual. The combined energy is moderate (480), but the surf is poor and choppy. Not your day.
Tuesday the 14th through Wednesday the 15th is the same story: NW swell at 5ft to 7ft, short period, cross-on wind. The energy hits strong (727) by Wednesday afternoon, but it’s all wind-chopped. No thanks.
Then things get weird from Thursday the 16th into Friday the 17th. The swell drops, but the period gets long. Thursday morning has a tiny 2ft WNW swell with a 19-second period, and the energy is still moderate (633). Friday morning has a 3ft WNW swell with a 17-second period and a huge energy reading of 1092. That’s a lot of energy for a small wave, but the wind is cross-on. For a river mouth, a long-period groundswell can be a handful—it tends to break straight and fast. Still, something is brewing.
Saturday the 18th and Sunday the 19th are the first real chances. The wind eases. Sunday afternoon looks like the best of the first week: a 3ft SW swell with a 17-second period, and the wind is onshore but light at 6 mph. The energy is strong (951), and it’s a 2/10. It’s marginal, but it’s the cleanest we’ve seen. That’s your early highlight.
From Monday the 20th to Wednesday the 22nd, the swell drops back to small, weak NW pulses. The wind is cross-on or light onshore, but the energy is low (around 150 to 384). Nothing to write home about.
Now, the real standout comes late in the window. The last few days of July and into the 28th show a serious ramp-up in size. Friday the 24th afternoon has a 7ft NW swell with a 7-second period, and the wind is light and onshore from the WNW. The energy is strong (743). Saturday the 25th morning pushes to 8ft NW, still onshore light wind, and the energy jumps to 1214. The rating is a 2/10, but this is the first time the size is proper and the wind is decent.
But the real highlight is Sunday the 27th and Monday the 28th. Sunday morning has a 10ft NW swell with a 9-second period, and the wind is light and onshore from the WNW. The energy is very strong (1743). Monday the 28th afternoon has a 10ft NW swell, same period, light onshore wind, and a rating of 3/10 (the highest we get). The energy is 1446. This is big, powerful swell. For a river mouth, 10ft is expert territory. It’s going to be a heavy, fast wave. If you’re a solid surfer, Monday the 28th afternoon is the pick of the entire 16 days. The wind is good, the size is there, and the juice is pumping.
Crowds? This spot is often busy, so expect company if you go for that late window.
In short, the first week is a washout. Sunday the 19th afternoon is your only decent early session. The real fire comes in the last few days, peaking on Monday the 28th. It’s a long-range call, so less certain, but the numbers say it’s the one to watch.
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.

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.
