The Lowdown
G’day, Rusty here. Look, I’m gonna level with you – this is a tough stretch for Navarro Rivermouth. We’ve got a 16-day window staring us in the face, and honestly, there’s not a single session I’d be racing to get out for. The first real surfable moment doesn’t even show up until Monday the 20th of July, and even then, it’s a real struggle to find something clean.
The whole pattern is dominated by a persistent cross-onshore wind from the northwest, which is just ruining everything. For the first few days, from Friday the 17th through Sunday the 19th, it’s a write-off. We’ve got a long-period groundswell (17 seconds) rolling in around 3ft to 5ft, but it’s all cross-on and choppy, with the combined swell energy sitting at 1040 on Friday – that’s a lot of energy, but with the wind, it’s just messy. You’d be paddling your brains out for nothing.
Now, Monday morning the 20th of July is the one bright spot. It’s glassy. The wind goes glassy, which is a major positive. We’ve got a 5ft swell from the NW, period is a short 8 seconds, and the combined energy is moderate at 479. The forecast says “expect good surf conditions,” but it’s a river mouth that’s inconsistent and rarely breaks, so don’t get your hopes up too high. It’s a beginner spot, so that size is fine, but it’s also a spot that can be a bit of a lottery. The water temperature is about average for the time of year here, nothing unusual.
Tuesday the 21st of July afternoon is the next maybe. The wind goes glassy again, but the swell drops to 3ft with a short 8-second period and the energy is weak at 173. It’s surfable, but very ordinary.
After that, it’s back to the same old story. From Wednesday the 22nd right through to the end of the month, it’s all cross-onshore winds and poor surf. The swell actually builds up – by the 28th of July we’re seeing 7ft from the NW, and on the 1st of August it hits 8ft, with combined energy readings of 1238, which is strong. But the wind is always cross-on from the NW, making it choppy and ugly. The period is short (5-9 seconds), so it’s just windswell mush. Anything over 8ft is only for experts anyway, but with this wind, it’s a mess. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
So, bottom line: there’s one window on the morning of Monday the 20th of July that’s worth a look if you’re desperate. Otherwise, it’s a long, blank run. The forecasts can change, but for now, it’s a tough one.
Rusty.
