The Lowdown
G’day, Rusty here. Look, I’ve had a good stare at the charts for Wharariki Beach, and I’ll be straight with you – it’s a frustrating run ahead. For the next 16 days, there’s no real window of quality surf. We’re looking at a blank spell that stretches for days on end, with only a couple of fleeting, marginal moments that don’t really stack up. The ocean’s just not playing ball for paddle surfing.
Right now, starting Friday the 28th of August, it’s a write-off. We’ve got a 13ft swell thumping in from the NNW, but with a strong 28 mph cross-onshore breeze, it’s a total mess out there. The combined energy is a hefty 2675 – that’s strong, but completely unsurfable in these conditions. That theme sticks around.
Saturday the 29th offers a brief glimmer in the morning – a drop to 5ft from the west, with a clean cross-off wind. But the swell period is a short 9 seconds and the combined energy is weak (692), so it’s just not got any grunt. The afternoon gets even smaller and cleaner, but at 1ft with a 20-second period, it’s too small to ride.
Sunday the 30th has a 7ft groundswell in the morning from the west, period 17 seconds (very long period), combined energy moderate at 2423, and clean cross-off wind. It’s the first day that looks interesting, but the forecast score says it’s still marginal due to tide and swell size. The afternoon picks up to 8ft (3663 energy), but the wind jumps to a near gale at 34 mph – blown out.
Monday the 31st and Tuesday the 1st of September see the swell push up to 12ft to 10ft from the west, with very long periods (13-15 seconds). The combined energy is strong to very strong (3309 to 4869). The wind is cross-off and clean. But here’s the thing: the forecast flat-out says it’s too big for this break. 12ft waves at Wharariki? That’s expert territory, and even then, the conditions are just too heavy for a proper session. Not recommended for anyone.
From Wednesday the 2nd of September through to Monday the 7th of September, it’s a consistent run of poor conditions – messy cross-onshore winds, big swells hitting 8ft to 12ft, and no clean windows. The combined energy remains strong (1683 to 4869), but the wind keeps blowing it out. On Wednesday the 2nd, there’s a 7ft to 8ft west swell with a long 14-second period and clean wind, but the energy is still moderate (1907) and the overall call is poor.
Then, on Wednesday the 9th of September, we get the one real standout of the whole outlook. In the morning, the wind dies right off – a light southerly breeze at just 3 mph, glassy offshore. Swell is a clean 7ft from the west, period 12 seconds (good groundswell), combined energy moderate (1504). The forecast says excellent conditions for experienced surfers. The afternoon holds up with a light east-southeast cross-off at 6 mph, swell 7ft but period drops to 9 seconds (short period), energy weak (804). The morning session is the pick. Keep in mind, at over 5ft it’s too big for beginners.
The rest of the fortnight is a mess again – strong winds, lumpy cross-chop, and big swells (10ft on the 10th and 12th of September) that are too big for the break. The 11th of September has a 8ft to 7ft west swell with moderate energy and clean wind, but it’s only rated as marginal.
So, the bottom line: Wharariki Beach is a consistent spot that normally offers up plenty of fun, but this forecast run is a dud. There’s one shot on Wednesday the 9th of September morning – that’s your best chance for clean, powerful waves. For the rest? Honestly, the setup looks more interesting for the kite crew than paddle surfing, with those strong cross-off winds and solid swell days. Hold tight and hope the charts change.
Rusty.

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.
