The Lowdown
Alright, let me level with you. It’s been a lean stretch here at Whangamoa and it’s gonna stay that way for a while. We’ve got a solid run of days with no real surf on offer – from now, Tuesday the 15th of September, all the way through to the morning of Friday the 18th, there’s nothing doing. Flat spells and poor conditions dominate.
First sign of anything remotely surfable shows up on Saturday the 19th of September, in the morning. We’re talking tiny 1ft NW groundswell with a very long 15-second period, and glassy conditions – zero wind. Combined energy is weak at 57. It’s surfable but very ordinary. The water temp is about average for this time of year. That’s the only window with a pulse worth mentioning, but honestly, it’s small, inconsistent, and the long period means it’ll be tricky on this sandbar setup – better suited to a point or reef. Still, if you’re desperate for a paddle, that’s your best shot.
After Saturday morning, it’s back to poor surf and next to nothing for days. A little bump of 3ft NW swell on Sunday the 27th of September morning might catch your eye, but with a cross-shore breeze and only 80 combined energy, it’s not gonna deliver much.
Bottom line: there’s one standout window – Saturday morning the 19th – but it’s tiny, inconsistent, and only for the keenest. Don’t hold your breath otherwise.

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.
