Alright folks, Rusty here. Let’s see what we’ve got for the next couple of weeks at Whangamoa.

Overall, it’s a pretty grim run, to be honest. We’re looking at a long stretch of poor conditions kicking off right away, with a chunk of nothing days in the middle. The only real hope is a potential window around the 16th of July, but even that has its issues.

We start off this Sunday morning, the 5th of July, with a bit of a tease. There’s a 5ft swell pushing in from the NNW, but it’s wrapping up from the NW which isn’t the optimum direction for this sandbar. The water’s sitting at 57°F, which is about average for the time of year. The wave energy is moderate at 491, but it’s sloppy with onshore wind. That pretty much fizzles out by the afternoon, with smaller 4ft swell and cross-shore wind killing any real quality.

Then we hit a massive, painful lull. From Monday the 6th of July all the way through to the morning of Wednesday the 15th of July, there’s really nothing worth paddling out for. The swell either disappears completely, or it’s tiny and wind-battered. Thursday the 16th of July shows a flicker of life, with a clean, glassy morning and a building 4ft NNW swell. The energy is solid at 206, and those light WNW winds would have it looking clean. But it’s a sandbar, and the groundswell potential is there. The problem is, by the afternoon it’s onshore and messy, and the following days aren’t much better.

Forget the rest of that week into the 20th. There’s some small swell, but it’s lumpy, onshore, or just ordinary.

The Best Bet: If you’re desperate and have the patience of a saint, your only real window is the morning of Thursday, July 16th. That early glassy session with 5ft from the NNW is the standout. It’s not huge, and it’s a sandbar, but it’s the best looking thing in a forecast full of nothing. Just don't expect much else after that.

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.
