The Lowdown
Alright folks, Rusty here. Let's have a look at what Wharariki Beach has on offer. The forecast kicks off on Wednesday, September 2nd, but don't get too excited. We're looking at a solid, clean swell early on, but it's blown out by some nasty winds. It's a rough start.
We kick off on Wednesday the 2nd with a big 8ft swell from the west, but a near gale cross-off wind is howling at 31 mph. The energy is strong at 3207, but with those winds, it's not going to be pretty. Thursday the 3rd drops a bit to 5ft, but it's cross-on and messy with rain. Not your day.
Friday the 4th is a write-off – the swell jumps back up to 12ft, and a near gale is making a mess of things. That's expert-only territory and even then, the wind is just too strong. Saturday the 5th is the first glimmer of hope. We've got an 8ft west swell with a long 14-second period, and the wind is a clean cross-off in the morning. The energy is pumping at 2930, but the forecast says it's only marginal. It could be worth a look if you're keen, but don't expect perfection. Sunday the 6th is a total washout with onshore rain and strong breezes.
Now, here’s where it gets interesting. Monday morning, September 7th, things start to settle. The swell drops to 7ft from the northwest, and we get a gentle cross-off breeze making things clean. It’s a marginal call, but a solid improvement. Then Tuesday the 8th is the first real standout. We have a 6ft west swell, a 12-second period, and a light offshore breeze from the east at 6 mph. The energy is moderate at 931, but the forecast says "expect very good surf conditions." This is your window for a clean, fun session.
The middle of the week fades out quickly. Wednesday the 9th through Friday the 11th is flat and weak – swell drops below 2ft, and the wind is all over the shop. A real gap in the action. Saturday the 12th morning offers another chance with a 4ft west swell, a 16-second period, and a light offshore breeze. It's clean and the energy is moderate at 795, but it's small.
Now, keep your eyes on Sunday the 13th. This is the big one. The swell jumps to a massive 12ft from the NNW with a 10-second period, and the energy is through the roof at 2931. The wind is a moderate cross-shore. The forecast says it's too big for this break. That's a warning – this is expert-only, and even then, it's going to be a beast. Monday the 14th is back to a smaller 3ft, and the wind picks up again. Tuesday the 15th has a 7ft west swell in the afternoon with a clean cross-off, but the strong breeze will mess with it.
Finally, Wednesday the 16th is another monster day – an 12ft west swell with a very long 17-second period and an energy reading of 6686. The wind is almost nothing in the morning, a slight air at 3 mph, making it glassy. But again, the forecast says it's too big for this break. It's a heavy, powerful groundswell. Thursday the 17th drops to 7ft, and a light offshore from the ENE gives us clean conditions. It's marginal, but a decent end to the run.
So, the best on offer? Your absolute standout is Tuesday morning, September 8th – a clean, fun-sized swell with offshore winds. The second standout, for the big-wave hunters only, is Sunday the 13th and Wednesday the 16th, but only if you're an expert and know the break well. Those are big, powerful swells.
Rusty out.

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.

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.
