Table - best surf conditions forecast for Nera Rivermouth over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s on offer. Honestly, it’s a pretty grim stretch for the next couple of weeks. The only spot in the frame is Nera Rivermouth, and it’s an inconsistent, sheltered river-and-beach setup that’s really just for beginners. The water temp is sitting at 74°, which is about average for this time of year.
We’re starting off with a whole lot of nothing. From Friday the 10th right through to Tuesday the 15th, the conditions are just poor – tiny swell, messy wind, and the energy is weak. The combined energy on Friday morning is only 98, and it doesn’t get much better. There’s a bit of a bump on Wednesday the 15th, with the swell hitting 2ft from the SSW and a period of 13 seconds, giving a combined energy of 186. The wind is clean and light offshore, so it’s surfable, but very ordinary. That’s the best we’ve got for a while, and it’s still just a beginner wave.
The next little window, and the only real standout across the whole forecast, is Friday the 17th in the morning. The swell ticks up to 3ft from the SSW, with a period of 12 seconds. The combined energy is 285 – moderate. But the real kicker is the wind: glassy. Absolutely flat calm. It’ll be clean as a whistle. That’s the one session to aim for if you’re desperate.
After that, things get rough again. The swell tries to push a bit bigger on Saturday the 18th, hitting 4ft from the SSW, but the wind is strong and cross-onshore from the WSW at 12 mph, making it choppy and rubbish. The combined energy reaches 438, but the quality is shot. That’s more of a kite-surfing setup than a paddling wave.
The rest of the second week is a write-off. The swell drops off, the wind stays onshore or cross-on, and the energy fades. By the 24th of July, there’s barely any swell at all. It’s a long, dry patch for Nera Rivermouth, and forecasts are going to have to change dramatically to bring anything decent.
Rusty.
