The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for us.
Overall, the 16-day window is a tough one. We’ve got a long stretch of small, messy, or onshore conditions, with only a few fleeting moments that might be worth a paddle. The action doesn’t really get going until the first recommendation, and then there’s a big gap of poor surf before a couple of late-arriving clean-ish windows.
Friday 7th August kicks it off at Haumoana River Mouth. Swell is a tiny 3ft from the SE, with a long 12-second period. The wind is light onshore ENE, so it’s bumpy, and the water is sitting at 53°F, a bit colder than normal for this time of year. The combined energy is weak (305). It’s marginal, but it’s the best we’ve got to start.
Saturday 8th August morning looks a little better. The swell drops to 1ft from the ESE, still 12 seconds, but the wind goes light WNW, which is cross-offshore. The combined energy is really low (91), and the waves are ordinary, but it’ll be clean. That’s about as good as it gets for a while.
After that, we hit a wall. From Saturday afternoon all the way through to Thursday 20th August, the surf is poor. There’s a mix of onshore winds, cross-shore chop, and tiny swell. The river mouth is just not offering anything rideable. That’s a solid 12-day run of flat or poor conditions.
Friday 21st August morning brings a bit of hope. The swell picks up to 3ft from the SE, with a 10-second period. The wind is light offshore from the W, so the surface will be clean. The combined energy is moderate (192). It’s not pumping, but it’s surfable and clean. That’s your best bet in the whole forecast.
Saturday 22nd August morning has a small window of clean, offshore WSW wind, but the swell is only 2ft from the ESE, so it’s tiny. Worth a look if you’re desperate.
For the standout, it’s got to be Friday 21st August morning at Haumoana River Mouth. The offshore wind will make it clean, and it’s the biggest, most energetic swell we see in the whole 16 days. It’s not huge, but it’s the best on offer.
Stay hopeful, the forecasts can change, but this one is a test of patience.
Rusty.
