The Lowdown
G’day, Rusty here, lookin’ over the charts for the next couple of weeks. Straight up, it’s a patchy run for Wharariki Beach. There’s a fair bit of swell on the way, but man, the wind is gonna mess with it most days. The first real standout I can see is Monday the 20th – that’s the one to pencil in. The water temp’s sitting at 58°, which is about a degree warmer than usual for this time of year, so nothin’ too wild there.
Let’s start with the first few days. Wednesday the 15th is a write-off – we’ve got 8ft of west swell with a 16-second period, which gives it some serious grunt (combined energy of 2993), but the cross-wind at 12 mph is just gonna mess it up. Thursday the 16th is a bit cleaner with a cross-off wind, but it’s blowin’ 25 mph, and that’s just too strong for a good session. The swell’s still around 7ft, which is borderline for all but the most experienced. Friday the 17th drops a bit to 5-5ft, but you’re still lookin’ at a 15-19 mph wind. Saturday the 18th is a total no-go – 8ft swell with a near gale blowin’ 31 mph? That’s kite-surfing weather, not paddle surfing.
Now, Sunday the 19th is a bit of a tease. The swell’s down to 5ft, but the wind has swung around to the east at 15 mph, so it’s a messy cross-shore chop. Not worth it.
Here’s your best bet: Monday the 20th. The morning session is the pick. We’ve got a clean 4ft west swell rolling in with a 14-second period, and the wind is a light easterly at 6 mph, almost glassy. The combined energy is 504, so it’s got a bit of push without being too much. This is a solid, clean wave for an intermediate surfer. The tide might be a factor, but with these conditions, it’s gonna be fun. The afternoon sees a light cross-on breeze, so hit it early.
After that, things drop off again. Tuesday the 21st is tiny – 2ft – and Wednesday the 22nd is even smaller, with a short-period wind swell that’s a mess. Thursday the 23rd gets a bit of a clean-up with 3ft and light winds, but it’s real small. Friday the 24th and Saturday the 25th are a write-off with strong winds or rain.
Now, lookin' a week ahead, Sunday the 26th looks promising. We’ve got 8ft of west swell at a 16-second period, combined energy of 3171 and 4272, with a cross-off breeze. That’s a lot of water movin’, but it’s clean. It’s a bit big for beginners, but for the experienced crew, that could be a ripper. Monday the 27th, though, it’s gonna be 10ft – that’s only for the experts, and the wind is gonna be howlin’ at 28 mph, so it’s gonna be a beast. Tuesday the 28th is still windy and messy.
So, in short: the best day on offer is Monday morning the 20th – clean, light winds, and a fun 4ft swell. The long-range standout is Sunday the 26th if you’re an expert lookin’ for a solid, clean 8ft groundswell, but keep an eye on that wind. It’s a long wait, but there’s a couple of decent windows.
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.
