G’day, Rusty here. Let’s have a yarn about what’s coming up at Navarro Rivermouth.

Honestly, it’s a tough stretch ahead. The whole 16-day window is pretty much a write-off for decent surf. There’s only a couple of mornings that might be worth a look, and even then, it’s a bit of a gamble.

We kick off with some average conditions straight away. Saturday, July 11th afternoon has some swell at 5 ft from the NW, but the period is a short 6 seconds and it’s messy. The combined energy is weak at 298. Wind is cross-on from the NW at 9 mph, making it choppy. Sunday and Monday see the swell push up to around 7 ft to 8 ft, still NW and with a period of 8 seconds, but the wind keeps blowing cross-on, spoiling any chance of clean waves. Energy gets up to moderate values like 471 and 668, but the quality ain’t there.

The water temp right now is 54°, which is about 2° cooler than normal for the time of year – nothing too unusual, just a bit nippy. This spot is a rivermouth, pretty exposed to the NW swell, but it’s also inconsistent, and with the wind never swinging offshore, it’s a struggle. The cheapie’s a beginner-friendly break, but the cross-on wind and short period won't help much.

The whole first week (July 11 to late July) is dominated by poor surf conditions. The swell stays between 5 ft and 8 ft, mostly from the NW, with periods of 6 to 8 seconds. Energy climbs into the moderate range, even hitting strong on the 17th July Friday morning (1788), but the wind report keeps saying “cross-on” and “choppy” or “fairly choppy,” so it’s all a bit of a mess. On a few mornings – like July 18th Saturday morning, July 20th Monday morning, and July 21st Tuesday morning – the wind drops to a gentler breeze, and the surf gets labelled “marginal.” Those could be the pick of an ugly bunch, with 7 ft to 7 ft NW swell and a period of 8 to 9 seconds, but they are still cross-on, not clean.

There is a real gap in quality for days at a stretch. Almost every session is scored as poor, with no standout clean window. The only real highlight might be the morning of July 24th Friday. The swell drops right off to just 1 ft, but it’s from the SW with a very long period of 26 seconds and light onshore wind from the WNW at 6 mph. That’s a groundswell of the highest order, but it’s tiny and the direction doesn’t match the optimum NW for this break, so don’t get your hopes up.

For a break that’s already inconsistent, this is a pretty blank run. It tends not to stay this poor for long, but for now, it’s a waiting game. If you’re desperate, the mornings of July 18th or July 20th could offer the least terrible waves, but don’t expect anything special.

Stay patient, mates.

Rusty.
