The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. The next 16 days are looking pretty grim for Whangamoa. We’ve got a real long stretch of flat or near-flat conditions, with only a few fleeting moments of surfable, but ordinary, waves. The water is sitting at 55°F – about average for this time of year, so no surprises there.
The first real chance to get wet doesn’t look promising. Saturday morning, July 25th, we’ll see a 4ft swell from the NNW, but it’s only an 8-second period – that’s short-period windswell, not much grunt behind it. The combined swell energy is moderate (172), and with a cross-off SSW breeze at 6 mph, it’ll be clean enough, but the waves will be pretty weak and messy. Honestly, it’s just surfable, nothing to write home about. Saturday afternoon drops to 3ft with the same short period, and showers moving in.
Sunday the 26th, the morning is a total write-off with no swell. But… Sunday afternoon brings a little glimmer. A tiny 1ft swell from the NW, but it’s a long 14-second period. That’s a proper groundswell, and with glassy conditions (0 mph wind from the north), it’ll be clean as a whistle. The wave energy is low (79), so don’t expect much push, but if you’re on a log or a funboard, you might get a few long, slow rollers. It’s the best of a bad bunch, but only just.
Monday morning the 27th is similar – 1ft at 13 seconds, with a light offshore SSE breeze at 3 mph. Clean, but tiny. That’s the last of the groundswell before the tank runs dry.
From Monday afternoon right through to Tuesday, August 4th, it’s a total desert. Over a week with nothing worth paddling out for. A few days have tiny little bumps, some glassy conditions, but the swell is either non-existent or under 1ft with weak energy. The 30th and 31st of July even see a spike in swell – 6ft and 6ft – but the wind is howling onshore at 19-22 mph, making it a complete mess. That’s more of a kite-surfing setup than a paddle-surfing one.
The only other blip on the radar comes on Tuesday afternoon, August 4th. A 1ft swell from the NW with a very long 16-second period, light cross-off wind, and clean conditions. The energy is weak (64) but it’s glassy. A long-period groundswell like that at a sandbar break like Whangamoa can be tricky – it might break too straight – but when it’s this small and clean, it’s worth a look for a quiet session.
After that, it’s back to flatness for the rest of the forecast. Some glassy mornings, some offshore breezes, but no swell to speak of.
So, to wrap it up: the only standout is Sunday afternoon, July 26th, and maybe Monday morning the 27th, for the cleanest and longest period waves. But they’re tiny. The rest is a wait-and-see game. It’s a tough run, but it won’t stay this way forever.
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.
