The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Whangamoa. Gotta be straight with you: the next couple of weeks are looking pretty grim. We’ve got a long dry spell ahead, so don’t be in a rush to grab your board.
The pattern for the next 16 days is dominated by onshore and cross-onshore winds, with only a couple of very brief windows where things might line up. The water temp is sitting at about 55°F, which is pretty normal for this time of year, nothing unusual there.
Looking at the first recommendation, which is a bit of a surprise, we don’t see anything worthwhile until Thursday, the 11th of September. That’s a full week of nothing but poor surf conditions and flat spells from now until then. A real bummer.
So, on Thursday afternoon, the 11th of September, we finally get a pulse. Swell will be pushing 4ft from the NW with a very long period of 19 seconds. That’s a proper groundswell, and the combined energy reading is a solid 1033 (moderate to strong). This kind of long-period NW swell can get a bit walled and fast at a beach setup, but at a sandbar like Whangamoa, it might just offer up some decent, powerful lines. The catch is the wind, which will be onshore from the NW at 9 mph. It’s not ideal, but it’s the only real option on the table. The forecast is only a rating of 3 out of 10, but in a desert, a puddle looks like an ocean. Crowds are never an issue here, so you’ll have it to yourself.
After that, it’s back to the drawing board. Saturday the 13th and Monday the 15th have tiny, weak pulses (0.7ft and 0.7ft) with long periods, but basically no energy behind them, so they’re not worth paddling out for.
That’s about it. One day, one chance. If you’re desperate, the 11th is your only shot. Otherwise, the wait continues.

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.
