The Lowdown
G’day, Rusty here. Let’s talk about what’s happening at Waiwakaiho. This sandbar break is fairly consistent and open to the swell, so there’s plenty to work with. Water temp is about 58°F, which is normal for the time of year. The overall pattern? A heap of surf on the way, but wind’s gonna be the decider – you need to pick your windows.
Starting Tuesday the 8th of September – morning is glassy with a 4ft swell from the WSW at 11 seconds, a nice long-period groundswell with moderate energy (821). That’s the morning session to nail. Afternoon goes cross and messy, so don’t bother.
Wednesday the 9th morning offers a smaller 3ft swell with a light cross-off breeze – clean but not a standout. Afternoon onshore, no good.
Thursday the 10th is a complete mess – onshore winds, lumpy, and that afternoon has a 0.7m swell at 22 seconds – that’s a very long period but the wind spoils it.
Friday the 11th of September – this is the big one. Morning has a 10ft swell from the WSW at 19 seconds, very long period groundswell, massive energy (7228). Light cross-off wind makes it clean and powerful. This is for experts only – over 8ft, so too big for most. Afternoon gets windy and lumpy.
Saturday the 12th morning – 13ft swell, again huge (5372 energy), light cross-off, clean. Expert only. Afternoon ruined by cross wind.
Sunday the 13th – 6ft but cross wind all day at 35 km/h – choppy, not worth it.
Monday the 14th morning – glassy, 6ft swell at 16 seconds (2404 energy – moderate to strong). Clean and fun for experienced surfers. Afternoon cross and messy.
Tuesday the 15th through Thursday the 17th – onshore winds, lumpy, big swells but blown out. This stretch is better for kite surfing than paddle surfing.
Friday the 18th – morning is near gale, forget it. Afternoon has clean cross-off but it’s 10ft with strong breeze – marginal.
Saturday the 19th morning – 8ft with gentle cross breeze, not clean enough to call a standout. Afternoon lumpy.
Sunday the 20th through Monday the 21st – all onshore, poor.
Tuesday the 22nd of September – another standout morning. Offshore wind from the SE, 10ft swell from the WSW at 16 seconds (4637 energy – very strong). Excellent for experts. Afternoon gets strong cross wind.
Wednesday the 23rd morning – same again, 10ft, 17-second period, clean cross-off (4590 energy). Another excellent morning for the experienced crew.
The two best windows are Friday the 11th and Tuesday the 22nd mornings – big, clean, long-period groundswell, but expert only. For intermediates, Tuesday the 8th morning with 4ft and glassy conditions is your best bet. Crowds can show up at Waiwakaiho sometimes, so be ready.
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.
