The Lowdown
G’day, Rusty here, and I’ve got a good hard look at what’s coming for Wharariki Beach. This isn’t a rushed season; we’ve got a bit of a slow cooker for the next week, but patience is going to pay off.
The week kicks off with a glassy, clean Monday afternoon (27 July). We’ve got a 4 ft swell from the west, with a long 12-second period giving it some real shape. The combined energy is a solid 497, and the water is sitting at 58°, which is about average for this time of year. With the wind glassy from the NE, it’s a proper session for an intermediate who wants to get into some lined-up, clean waves. This is a good start, but it’s not the main event.
The next few days are a bit of a write-off. Tuesday morning (28 July) is cross-off, but only 3 ft and the energy drops to 194. It’s surfable, but you’d be better off waiting. Wednesday morning (29 July) has another glassy window with 3 ft and 218 energy, but it’s small. By Wednesday afternoon, the WNW wind kicks up to 16 mph, and while the swell period jumps to 14 seconds, it’s cross-shore and messy. Thursday (30 July) is a total mess with fresh to strong cross-onshore winds, and Friday (31 July) sees a massive 12 ft to 13 ft swell from the west, but it’s blowing a near gale at 34 mph. The combined energy skyrockets to 1658 and then 4096, but the wind is cross-off and ripping. That’s expert-only territory, and honestly, it’s more of a kite-surfing show than a paddle session.
Now, the real standout. Clear your calendar for Monday morning, 3 August. The wind is glassy again from the ESE, and we’ve got a 4 ft swell from the west with a very long period of 19 seconds. The energy is 957. This is a proper groundswell, and for a beach break, that long period can make it a bit straight, but Wharariki can handle it with the right tide. The conditions are clean, and the forecast is rated as very good. This is the best of the lot.
Then, on Wednesday afternoon, 5 August, we get another clean window. The wind is offshore from the SSE at 16 mph, and we’ve got 6 ft from the west with an 8-second period. The energy is 571, and the conditions are clean. It’s a shorter period, so it’s a bit more playful, but it’s a solid session.
The second week gets a bit more ordinary. Saturday morning, 10 August, has a tiny 1 ft swell with only 72 energy. It’s clean, but you’ll be looking for any ripple. Tuesday morning, 11 August, is also clean with 1 ft and 83 energy – surfable, but very ordinary. Keep an eye on the longer-range forecasts, because this blank run might shift, but for now, it’s a quiet end to the outlook.
Overall, the best on offer is definitely Monday morning, 3 August, for that glassy, long-period groundswell, and Wednesday afternoon, 5 August, for the offshore, punchy waves. The rest of the first week is either too small, too windy, or too big.
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.
