The Lowdown
G'day, Rusty here. Let's have a look at what's cookin' for Wharariki Beach over the next couple of weeks.
Alright, it's a bit of a slow start for Wharariki Beach. We've got a solid week of pretty ordinary conditions to wade through before things start to get interesting. The first few days are a write-off, with strong winds and messy surf. The water temperature is sitting at 57°, which is a full 2° warmer than usual for this time of year, so that's a bit of a treat.
We're looking at a long, quiet stretch from now until around the 10th of September. The swell is small, and for the most part, the wind is just not playing ball. You'll be sitting on the beach for a few days, that's for sure.
The first real glimmer of hope comes on Thursday morning, the 10th of September. There's a tiny 2ft swell from the west, but it's got a *very* long period of 17 seconds. The combined energy is moderate (475), but with a fresh cross-offshore breeze, it might be enough for a sneaky session on a longboard. It's a bit marginal, but keep an eye on it.
Now, the real standout is shaping up for Friday, the 11th of September. The morning is looking at a solid 8ft west swell with an 18-second period, which is a proper groundswell. The combined energy jumps to a very strong 4391. By the afternoon, it's even bigger at 10ft, and the energy is a massive 5675. The wind is a clean cross-offshore from the WSW. This is going to be a big, powerful day. The swell is over 8ft, so this is for experts only. The long period means it'll be breaking a bit straight on the beach, but the power and the clean wind will make for some serious, heavy barrels. This is the best of the whole run.
The swell hangs around for the next few days, but it's plagued by strong winds. Friday the 18th of September morning is another one to circle. The wind drops to a light breeze from the SSW, keeping it clean, and there's a solid 7ft west swell with a 16-second period and a very strong combined energy of 1958. The conditions are described as excellent for experienced surfers, which is exactly what it is. The crowds here are never an issue, so you'll have that power to yourself.
Towards the end of the run, on Sunday the 20th of September, we get a bit of a different flavour. The swell is 8ft from the west, with a very strong energy of 3653. The wind is light from the east, which is a light cross-shore, and the water is glassy. It's a bit on the big side for beginners, but for the experienced crew, it's a solid, clean option.
So, to sum it up: the first week is a bust. The 11th of September and the morning of the 18th of September are your standout sessions. Get out there for the big ones if you've got the nerve.
Rusty.

Information about the Wharariki Beach Surf forecast
The above surf forecast table for Wharariki Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Wharariki Beach can be found by selecting the local surf guide option on the grey menu. Our Wharariki Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Wharariki Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Wharariki Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
