The Lowdown
Alright, it’s Rusty, and I’m looking at the surf for the next couple of weeks. We’ve only got one spot on the radar, and it’s a bit of a specialist wave.
The main action is at Haumoana River Mouth. It’s an advanced river bar set-up, and it’s fairly consistent, but it’s not for the faint-hearted. The water temp is sitting at 54°, which is a bit colder than what we’d usually expect for this time of year, so you’ll want a good hood and gloves.
We’ve got a bit of a quiet start, but things build up. The best bet for the first week lands on Wednesday, August 5th. The morning session is looking clean with a moderate offshore breeze from the SSW. We’re looking at a 4 ft swell from the SE, and the combined energy is pumping at 373 (moderate wave energy). That’s a solid, workable wave for the advanced crew, and the offshore wind will keep faces clean. The afternoon stays rideable but loses the wind.
Thursday, August 6th is also worth a mention. The morning has a clean 3 ft SE swell with a gentle offshore from the WSW, and the energy is still moderate at 218. It’s a step down in size but will be consistent and clean.
After that, the swell fades into very ordinary, small conditions for the rest of the first week and into the second. There’s a big gap of poor surf until Friday, August 14th. That morning brings a 5 ft NE swell, with energy hitting 502 (strong energy), but the wind is cross-onshore, making it messy. It’s a marginal call, and the river bar can get tricky with that much energy and a cross-wind. It might be more interesting for kite surfers than paddle surfers that day.
The final weekend, August 16th, has a tiny 3 ft NE swell with a clean offshore wind Sunday morning, but it’s small and weak. The rest of the run is mostly small, choppy, or blown out.
So, for the standout: Wednesday morning, August 5th is your best bet. It’s not huge, but it’s clean and has enough push. After that, you’re waiting for a long stretch of small stuff.
Rusty.
