The Lowdown

G’day, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks. We’ve got one spot firing on all cylinders, but it’s a bit of a picky window. The water’s sitting at 56°F, which is about normal for this time of year, so no worries there.

The action kicks off early Wednesday morning at Wainui Beach - Stockroute. It’s not huge, but there’s a clean 4ft SE swell with an 8-second period, and the wind is dead glassy out of the WNW. This is a beach and reef setup, so it’s got a bit of variety, but it’s an advanced wave. The energy is moderate (212), and the conditions are looking sweet. This is the first good window, so if you can get out there, do it. The afternoon sees the wind swing NE and go cross-on, dropping the swell to 4ft. It’s still surfable, but the quality fades.

Thursday brings a drop in size—2ft in the morning with a moderate offshore from the NW. It’s clean, but the energy is weak (59), so it’s pretty average. The afternoon is glassy but even smaller at 2ft. Not much to write home about, just a paddle if you’re keen.

Friday morning turns it on a bit with a 5ft SSE swell, but the wind is howling cross-shore from the SSW at 25 km/h, making a mess. Not great. The afternoon though, is the standout. The wind drops to calm, leaving it glassy, and the swell holds at 4ft with moderate energy (257). This is a proper clean session. The period is short at 7 seconds, so it's a bit crumbly, but it's still good surf conditions.

Saturday drops right off. Small and messy, with a long-period groundswell of 17 seconds but only 1ft. Not worth your time unless you're just floating around.

Now, Sunday morning. This is the one to circle. The swell jumps to 5ft from the SSE with a 15-second period. The energy is strong (1017), and the wind is glassy out of the WNW. This is excellent surf for experienced surfers. The period is long, so at a beach and reef break, it might be a bit straight, but the power is there. This is your best bet for a proper wave. The afternoon sees the wind swing onshore and chop it up, so get your fill in the morning.

Monday morning remains solid with 4ft from the SSE, an 13-second period, and a light cross-offshore from the NNW. It’s clean and the energy is moderate to strong (580). Very good surf conditions. The afternoon goes cross-on, so the morning is the window again.

Tuesday comes in smaller at 3ft, still clean with an offshore, but the energy is low. Wednesday drops further. The rest of that week is pretty poor—small, weak, and choppy. Nothing worth getting excited about.

We’ve got a dry spell from Friday the 16th through to the following Tuesday. There’s a pulse of long-period energy coming through on the weekend of the 17th and 23rd, but the wave heights are tiny. It’s a flat patch.

Then we look ahead to the 23rd of September. This is another promising one, but it’s over a week away, so keep the enthusiasm in check. It’s showing 1ft from the SSE but with an 18 to 19-second period. The energy is moderate (248), and the wind is light and clean. It’s small, but the long period swing means there’s some push. For a spot like this, a long period groundswell is often best, but it’s still a small wave, so not a classic stand-out.

So, to be honest, the standout window is the Sunday morning, and to a lesser extent, the Monday morning. Get on it when the wind’s glassy and the swell’s got some power. The rest is mostly small and average. The long-range stuff on the 23rd is a maybe, not a certainty.

Rusty out.
