The Lowdown
Righto, let's have a look at what's cookin' for Raglan over the next couple of weeks. Ngarunui Beach has been dishing out some serious size, but it's been a bit of a battle with the wind. We're looking at a long stretch of big, powerful swell from the WSW, but the onshore and cross-onshore winds are going to mess it up for a while.
The first real chance to get wet without getting completely worked and blown off your board looks like it'll be Wednesday, the 9th of September. The morning is shaping up real sweet. The swell drops right back to a friendly 4ft, still coming from the WSW, and most importantly, we get a light offshore breeze from the ENE. That'll keep the faces clean. The wave energy is moderate (584) but with the glassy conditions, it'll be a welcome break from what's been going on. Don't expect anything massive, just clean, fun waves.
Now, for the experts only. The whole run from Friday the 11th through to Tuesday the 15th of September is pumping out swell over 14ft – that's an absolute beast with very strong wave energy, peaking over 12000 (combined energy). Some of those mornings, particularly Monday the 14th and Tuesday the 15th, have light to gentle cross-shore breezes which would make the conditions a bit cleaner for a big-wave paddle. But you'd better have your big-wave gun and a whole lot of nerve because 14ft to 16ft surf is not for the faint-hearted. The 14 to 15-second period means it's a deep, powerful groundswell, so it will be walling up. This is strictly for the crew who know what they're doing.
After that, the swell backs off a little through the 16th and 17th, but the wind stays messy. You might find a sneaky one on the 18th of September with a light cross-shore SSE wind and 5-6ft swell, though it'll be brief. Overall, it's a fortnight of two halves: a clean, small window this Wednesday, followed by a long stretch of dangerously big, powerful surf for the hardcore crew only.
