The Lowdown
Alright, Rusty here. Let’s talk about the next couple of weeks at Waiwakaiho.
Right now, the surf is actually looking pretty inviting to kick things off. Thursday morning is the standout window early on. We’ve got a clean 6ft swell rolling in from the WSW, period at a nice 13 seconds, and the wind is glassy out of the north. The water’s about average for this time of year, so nothing weird going on there. The combined swell energy is solid at 1059, so there’s plenty of push without being too heavy. This is a good, clean sandbar setup for an intermediate surfer. Crowds can show up now and then, so keep your eyes peeled.
Thursday afternoon sees a bit more wind, turning cross-on and making things choppier, so the shine wears off quick. Friday is a write-off with a big 10ft cross-on howl and messy conditions – that’s a hard pass.
Saturday brings some relief, but it’s marginal. Morning has a 4ft swell from WSW with a long 13-second period, but the wind is cross, so it’s a bit bumpy. The combined energy drops to 964, feeling weaker. Not worth rushing for.
Sunday and Monday get messy again, with strong winds and lumpy cross-shore chop. The swell size jumps up, but it’s all wind-affected and poor. Sunday morning has a 8ft WSW swell at only 8 seconds, so short and weak. Monday morning hits 15ft with a 14-second period, but the cross-wind ruins it. That’s too big and blown out for most.
The whole first week is pretty average after that Thursday morning window, with a lot of cross-on or cross winds and lumpy conditions. Not much to get excited about.
Now, looking into the second week, there are a couple of promising mornings if you can wait. Monday the 7th of September morning is a real gem on paper. We’ve got a 8ft W swell with a very long 17-second period, combined energy at a strong 4172, and light cross-off wind from the east. That’s clean, powerful groundswell that’s going to line up nicely on the sandbar. It’s only for experienced surfers at that size, but if you’ve got the skills, this is the best on offer. The long period might make it a bit wonky on a beach break, but with the wind being clean, it should still hold.
Tuesday the 8th of September morning is another solid call. A 10ft W swell at 11 seconds, combined energy 2034, with light cross-off wind from the south and clean conditions. Again, this is big and for the experienced crew, but the conditions are there.
The rest of that second week is mostly messy or blown out again, with strong winds and lumpy chop. Wednesday the 9th sees a risk of thunderstorms and near gale force winds, so stay out of the water. Thursday the 10th and Friday the 11th are still marginal with cross winds, though Friday morning has a 10ft WSW swell at a very long 17 seconds and gentle onshore wind – might be worth a look for the brave, but it’s not clean.
Bottom line: Thursday morning, August 27th, is your best early window for clean, fun waves. For the bigger stuff, wait for Monday the 7th or Tuesday the 8th of September mornings, but those are expert-only due to size. Otherwise, it’s a patchy couple of weeks with plenty of wind issues.
Rusty.

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.
