The Lowdown

Alright, mates, Rusty here. Let's have a look at the surf window for Wharariki Beach. We've got a bit of a slow start, but there are some proper sessions hiding in there if you know when to pick your moments.

The opening stretch is pretty average. We're looking at small, weak surf with a decent amount of energy behind it but nothing that's going to get the heart rate up. Thursday the 10th is all about small, weak surf with a decent amount of energy behind it but nothing that's going to get the heart rate up. The water temp is sitting at 57°, which is right around normal for this time of year.

The first real standout is Friday afternoon, the 11th. The swell jumps up to 10ft, with a long 18-second period and a solid 5472 (moderate wave energy) behind it. The wind is cross-off and clean, but this one comes with a warning label: it's predicted to be too big for this break. This is expert territory only. If you're not absolutely confident, give it a miss and enjoy the show from the beach.

Saturday the 12th continues the same theme with 10ft surf, but it's a bit shorter period. Still clean, still big, still one for the experienced crew only.

We get a drop through the middle of the week, with surf in the 5ft to 7ft range, but it's pretty ordinary. The wind picks up and makes things messy, and the quality just isn't there. Mostly rough and lumpy.

Going into the following weekend, the 19th and 20th sees big swell return, with 13ft on Saturday and 12ft on Sunday. The standout, though, is Sunday morning, the 20th of September. We've got 8ft of west swell with a 15-second period, and the wind goes totally glassy. This is the pick of the run. It's still big, so it's for experienced surfers, but the conditions will be as clean as they get. The energy is strong at 3297 (moderate wave energy), and west is right in the optimum direction for this spot.

After that, it's more of the same for the second week – swells in the 7ft to 12ft range but with onshore or cross winds and messy conditions. Hard to get excited about it. There are a few cleaner windows around the 22nd and 24th, but the wind is just too strong to make it worth paddling out. A lot of that look is more interesting for the kite crew than us.

So, bottom line: the first real highlight is Friday the 11th and Saturday the 12th for big, clean, expert-only waves. Then lock in Sunday morning, the 20th, for the best combination of size, direction, and absolutely perfect, glassy conditions. Don't bother with the rest unless you're desperate.

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. 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.
