The Lowdown
Righto folks, Rusty here. Let’s have a look at what the ocean’s got cookin’ for us over the next couple of weeks.
Alright, straight up, this is a heavy period. We’ve got a serious pulse of south-west groundswell on the way, but for a lot of the time it’s going to be too damn big and messy for a proper paddle session. The main break in the picture is Port Waikato-Sunset beach. This is an exposed, fairly consistent spot that handles swell from the SW, which is exactly what we’re getting.
The water temp is sitting at 58°F right now, which is pretty normal for this time of year, no major anomalies to worry about there.
The action starts on Saturday the 12th. We’ve got a massive 15ft SW swell rolling in with a 16-second period – that’s a long-period groundswell packing some serious power. The combined energy is huge at 10875. Now, that sounds epic, but at over 8ft this is big boy territory only. Plus the wind is a cross-shore 19 mph, so it’s going to be lumpy. Not a beginner’s day at all.
Sunday the 13th stays big and messy, and Monday the 14th is still pumping with 10ft SW swell and a 16-second period. The energy is still strong, readings around 4471 to 6621. The winds are cross or cross-on, so expect chop. Again, only for the experienced crew, and even then it’s a battle.
The middle of the week, from Tuesday the 15th into Wednesday the 16th, sees the swell drop back a bit. On Tuesday morning we’ve got 8ft from the SW (14-second period), with light cross-shore winds. Combined energy is 2066 – moderate. It’s still a solid size for intermediates, but the conditions are just “marginal.” The rest of the week looks average at best, with onshore winds and choppy surf.
Now, here’s the standout window. Friday the 18th is the jewel in this forecast. We’re still looking at a 10ft swell from the WSW with a 16-second period (combined energy around 3827), but the wind magic happens. On Friday morning we get a 12 mph offshore breeze from the ESE, cleaning things right up. By Friday afternoon, the wind drops to just 3 mph from the east, going glassy. That’s clean, lined-up waves. The only catch? 10ft is still big, so this is for experts only. If you’ve got the skill, this will be the session to chase.
After that, from Saturday the 19th onwards, it turns to rubbish. Strong cross-onshore winds, lumpy conditions, and persistent rain. The swell stays big (8ft to 12ft) but the quality is shot. There are a few flickers of decent swell around the 24th and 25th, but the wind is never in the right place to make it truly good for a paddle. Honestly, the set-up from the 19th to the 27th looks more interesting for the kite crew than us on surfboards.
So to wrap it up: there’s a lot of power in the water, but very few clean windows. The absolute best on offer is Friday the 18th at Port Waikato-Sunset beach – big, clean, and offshore, but experts only. If you’re not in that bracket, keep an eye on the charts for a change, because right now the rest is a write-off.
Stay safe out there.
