The Lowdown
Alright folks, Rusty here. Let’s get into it. We’re looking at a tough stretch ahead for Nera Rivermouth. Honestly, the first real window of decent surf doesn’t show up until Tuesday morning, 28 July, so we’ve got a bit of a wait.
The overall pattern is dominated by a persistent cross-shore wind from the SE for the first few days, which keeps things messy. The one standout moment comes on the morning of Tuesday, 28 July. The swell is from the SSW at 5 ft with a period of 12 seconds, showing moderate wave energy (634). The wind is a gentle cross-offshore (SE at 5 km/h), which will make the surface clean. For a spot that’s sheltered and inconsistent, this is a rare little gem. The optimal swell direction is SW, so this SSW swell is a good fit. Keep in mind, Nera Rivermouth is a river mouth setup, so that long period will hold up nicely there. The water temp is about average for the time of year, so nothing unusual there.
After that Tuesday morning window, it falls apart again. The wind swings back onshore or cross-shore, and the wave heights drop way down. From Wednesday 29 July through to the end of the run, we’re looking at a long stretch of poor conditions. Swell stays small, mostly under 3 ft, and the wind is almost always from the south or southeast, making it choppy or cross-chop. The energy is weak, with values like 31 mm and 74 mm on 3 August, just not enough to get excited about. There’s a brief moment on Thursday 30 July morning with a clean 1 ft SSW swell (16-second period, 193 energy), but it’s tiny and the wind is offshore, so it’s rideable but nothing special.
For the rest of the first week of August, it’s a grim picture. Onshore winds and small, short-period swell keep the quality poor. The break is inconsistent at the best of times, and with this setup, it’s a waiting game. There’s frankly no other standout to recommend.
If you’re a beginner, the 5 ft on Tuesday morning is right at the edge of your comfort zone, but the clean conditions make it doable. For anyone else, that’s the only session worth paddling out for in the next 16 days. The rest is more interesting for kite surfers than paddle surfers, given the cross-shore wind and chop.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Nera 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.
