The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Honestly, it’s a pretty bleak run at Whangamoa for the next week or so. There’s just nothing doing. We’ve got a long stretch of flat, wind-affected days from Thursday the 16th right through until about Tuesday the 28th of July. The water temp is sitting at 55°, which is pretty much bang on average for this time of year. No surprises there.
Now, you’ll want to keep an eye on Wednesday the 29th of July, because that’s when the whole picture changes. We get a proper pulse of swell pushing in from the NNW, building to 6ft by morning with a short, fat period of 6 seconds, and the combined energy is moderate at 245. It’s clean with a light cross-off breeze, so it’ll be rideable for the average intermediate. But the real standout is Wednesday afternoon. The swell kicks up to 7ft from the NNW, period jumps to 8 seconds, and the energy jumps to 520 – that’s solid, powerful stuff. The wind is light and cross-on, so expect a bit of texture on the face but nothing that’ll ruin it. However, at that size, this sandbar is going to be a handful. It’s going to be too big for beginners, and even for the experienced crew, it’ll be a challenge. Crowds are never an issue here, so you’ll have it to yourself. That afternoon session is the best on offer by a long shot – powerful, consistent, and all yours.
After that little burst, Thursday the 30th drops back to 3ft from the north with a 8-second period, but cross winds will chop it up. Friday the 31st is written off with strong onshore winds and rain. So really, it’s all about that Wednesday the 29th afternoon if you’ve got the skills.
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.
