The Lowdown
Alright, folks, Rusty here. Let’s have a look at the surf forecast for Wainui Beach – Stockroute. It’s a bit of a mixed bag coming up, so let’s break it down day by day.
We start off with a bit of a flat spell. For the first few days, the swell is small and the conditions are just not there. The water is sitting at 55.2°F, which is about 2.3°F colder than usual for this time of year, so you’ll want the hood and gloves on.
The good news is that this isn't a forever thing. There’s some action building for the middle of next week. The standout window looks like it’ll be Monday the 17th. We’ve got a clean 4.9ft SSE groundswell with an 11-second period, and a gentle offshore wind. The energy is moderate at 534, and conditions are looking really clean. That’s your best bet for a proper surf in this stretch.
Before that, there’s a few days of onshore slop and small, weak waves. The wind swings around and just messes things up. Not worth getting too excited about. There’s a bit of a bump on Friday the 14th, with a 5.9ft NE windswell, but the period is short and the wind is cross-off, so it’ll be a bit lumpy and not the best quality.
Then we get to the big one. Around the 19th, the swell really kicks up, with waves pushing 11.5ft, but it’s accompanied by strong, messy cross-shore winds. That’s a washing machine, not a surf session. It’s big, but it’s not clean. This is more for the tow-in crew or maybe the kite surfers, as it’s going to be blown out.
The real gem in this whole period is that Monday the 17th. It’s a standout. The conditions should be glassy, the swell is solid, and the direction is right. After that, we’ve got some promise on the 21st, with a long-period 7.9ft SSE swell showing up, but the wind is a bit stronger and the tide could be a factor. It’s a promising sign for the following weekend, but we’ll have to see how it plays out.
It’s a wait-and-see for the end of the run, but that Monday is the one to circle. Get out there if you can.
