The Lowdown
Alright, Rusty here, let's chew the fat on what's coming up.
Right off the bat, it's dead. We’ve got a dry spell at Whangamoa (New Zealand) with nothing worth a paddle until Saturday the 8th of August. A few days of flat water, so don't bother rushing.
That Saturday morning, the 8th, we finally see a pulse. A small 3ft swell from the NNW, but with a short period of 8 seconds. The wind is glassy, which is a massive plus, but the wave energy is weak at 150. It’s surfable, but it’s a small-wave day.
The one that stands out, the real highlight, is Sunday afternoon, the 9th of August. The wind goes glassy again, and the swell bumps up to a fun 7ft from the NNW. The combined energy jumps to 788, which is proper power. The forecast says "expect very good surf conditions," and I’d be out there for sure.
Monday morning the 10th is a solid follow-up. Clean conditions, a 4ft swell from the NNW, and a nice cross-offshore wind. Energy at 235, so it’s got some push.
Now, Friday morning the 14th of August shows a 10ft swell, but that’s way too big for this spot. The water temp is about average for the season at 55°.
After that, it gets messy with smaller, choppier stuff, and then we hit another flat spell from the 17th through the 21st. There’s a tiny, glassy 3ft pulse on the 20th, but it’s weak.
Bottom line: save your energy for Sunday afternoon the 9th. That’s the session to aim for. Monday morning the 10th is a good second choice. The rest is mostly for the die-hards or the kite surfers.
Rusty.

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