The Lowdown
Alright, folks, Rusty here. Let’s break it down. For the next two weeks, we’ve got a big start, then a long quiet patch, and a real sweet spot at the very end.
Right now, Monday the 24th of August, Waiwakaiho is going off. We’ve got a 13-foot swell rolling in from the WSW, with a 15-second period. That’s some serious groundswell energy. The combined energy is 6903, so it’s packing a punch. Water temp is 57°, which is about average for this time of year. The wind is a cross-shore breeze at 12 mph, so it’s a bit choppy. The morning is the best bet, but the afternoon gets worse with the wind turning onshore. This is a big swell, well over 8 feet, so it’s for the experts only. Beginners, stay on the sand.
Through Tuesday and Wednesday, the swell drops, but the wind stays onshore and messy. The conditions are poor. Thursday the 27th has some cleaner spells, but the waves are still rough. Friday and Saturday are a total washout with strong onshore winds and lumpy, poor surf.
Then we hit a dry spell. From Sunday the 30th through the first week of September, the wind is relentless, the swell is either too small or too messy, and the scores are terrible. It’s a frustrating stretch of days with no real quality.
But hold on. The real pay-off is coming on Sunday the 6th of September. The conditions finally flip. The morning brings a light offshore breeze from the SSW, with clean waves. The swell is 6 feet from the WSW, with a period of 11 seconds, moderate energy. Then the afternoon? That’s the standout. The wind turns cross-offshore from the S, a light breeze, and the swell jumps to 7 feet from the WSW with a 15-second period, combined energy of 2342. The water will be clean and glassy. This is excellent surf, but at 7 feet, it’s still a bit hefty for beginners, this is for the experienced surfer.
And then Monday the 7th of September morning is worth a mention too. The wind goes glassy, from the NNE at just 3 mph. The swell is 6 feet, a bit smaller, but the glassy conditions will make it a dream for the experienced surfer. It’s a beautiful, clean morning wave.
So, the best of the whole run? It’s Sunday the 6th of September afternoon at Waiwakaiho. Clean, cross-offshore wind, solid 7-foot groundswell, and a long period. That’s the one to circle on the calendar. It’s a bit far out, so it’s promising but not locked in yet. The Monday morning the 7th is a close second with that glassy setup.
Remember, this is a sandbar setup, so it can be a bit inconsistent, but when it’s clean like this, it’s worth the gamble. Crowds are possible here, so get there early.
Rusty, signing off.

Information about the Waiwakaiho Surf forecast
The above surf forecast table for Waiwakaiho provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Waiwakaiho can be found by selecting the local surf guide option on the grey menu. Our Waiwakaiho 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 (Waiwakaiho) 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 Waiwakaiho 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.
