The Lowdown
Righto, gather 'round. Rusty here. Let's have a look at what's on the table for the next couple of weeks.
First off, I'll be straight with you—it's a tough start. We're looking at a long, dry spell with nothing worth paddling out for. The first real chance of a wave doesn't come until Friday the 24th of July, and even then it's a bit of a mess. The entire period from now until then is a total write-off. No surf to speak of, just flat or tiny, bumpy junk.
The first bit of energy rolls in on Friday the 24th of July, but it's not pretty. A strong NNW wind kicks up to 25 mph, pushing a stormy 7 ft swell straight onshore. The combined energy is moderate (462), but with that wind, it's a complete washout. Not for us.
Saturday the 25th of July is where things get interesting, but with a big caveat. The morning brings a solid 10 ft NW swell, with a combined energy of 855 (strong). The wind is light cross-onshore, so it could be clean, but the file says it's predicted to be too big for Whangamoa. This is expert-only territory, and even then, it's a maybe. The afternoon drops to a more manageable 4 ft, but the wind picks up and it gets a cross-chop. Not the standout.
The next real window is a week later, on Saturday the 1st of August. The morning has an 8 ft NNW swell with a clean, cross-off wind from the SW at 12 mph. The combined energy is very strong (912). Again, the file says it's predicted to be too big for this break. This is a big, powerful swell for the brave. The afternoon holds at 7 ft with a cross-shore wind, still a lot of energy (587). It's a solid session for the experienced crew, but the size is a real barrier.
Honestly, looking at this whole 16-day window, there's no single moment I'd call a true standout for the average surfer. The few days with swell are either blown out or simply too big for Whangamoa. The water temp is sitting around 56°F, which is about average for this time of year, so no surprises there.
The bottom line is: this is a lean period. We've got a long gap of nothing, then a couple of days where the swell is either messy or way too big. The first week of August looks like it might offer something, but it's a long way off and the forecasts could change. For now, it's a waiting game.
Rusty.

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.
