The Lowdown
G’day, Rusty here. So, looking at this 16-day stretch, we’ve got a bit of a slow start. The early swell is just too big for this break, and the conditions are all over the place. But if you can wait it out, there’s a few windows of clean glory.
At Port Waikato-Sunset Beach (New Zealand), the water is sitting at 57°F, which is about normal for this time of year. The first decent chance comes on the morning of Thursday, August 20th. The swell drops to 7ft from the SW, and here’s the magic: the wind is glassy, from the SSE at only 3 mph. The wave energy is moderate (1903), with a 14-second groundswell. This is for the experienced crowd only, as that 7ft is pushing the limits for most. It’ll be clean, glassy, and powerful.
After that, we hit a bit of a lull, with choppy and poor conditions through the 22nd and 23rd. Then, on Thursday morning, August 27th, there’s another clean window. A 6ft SW groundswell (15-second period) with a light SE cross-offshore breeze at 9 mph. Energy is moderate (1258). It’s a solid, clean option.
But the one to really get the blood pumping is Saturday morning, August 29th. The wind is glassy again, from the E at just 3 mph. The swell is 8ft from the WNW with a 10-second period – wind swell, but don’t let that fool you. The energy is moderate (1676) and the conditions will be perfect for the experienced surfer. That 8ft puts it in expert territory. Get out there as the sun comes up, because crowds here can be a thing.
If you miss that, Sunday morning, August 30th is a worthy backup. Another glassy start (ENE at 3 mph), with a 7ft WNW swell and moderate energy (1521). A little smaller, but still a beautiful, clean morning for those who know what they’re doing.
So, the first few days are a bust for good surf. The best bet is that glassy Thursday the 20th if you need a fix, but the real standout is that Saturday the 29th. Pin that one.
Rusty.
