The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got for the next couple of weeks.
First up, it’s a pretty slow start. There’s a long gap of nothing worthwhile, so don’t rush to get the board out. The first real chance to paddle out doesn’t show up until Saturday morning, July 25th, and it’s only just surfable.
The absolute standout is Saturday afternoon, July 25th, at Whangamoa. The swell comes up to 4ft, out of the NNW, with a 15-second period – that’s proper groundswell. The combined energy clocks in at 711, which is a solid thump. And the wind? Dead glassy. That’s about as clean as it gets. That’s the session to circle on the calendar. Water temp is around 55°, which is pretty normal for this time of year.
Sunday the 26th is completely flat. Monday morning the 27th has a tiny 1ft NW swell with a 12-second period, but it’s clean and cross-off – just enough for a longboard if you’re keen. Tuesday is flat again. Wednesday has nothing. Thursday the 30th brings a 6ft WNW swell, but it’s only 5-second wind chop and the energy is 169 – moderate and messy. Not worth the drive. After that, it’s mostly tiny or flat right through the first week of August. A small 0.7ft NNW groundswell on Monday August 3rd shows up with a 16-second period, but it’s barely a ripple.
So really, save your energy for that Saturday afternoon session. It’s the only true highlight. This spot is inconsistent, so a run of flat days like this is normal for the area. Forecasts can change, so keep your eyes peeled.
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.
