The Lowdown
Righto, let’s have a look at what’s on offer around here. To be honest, the next couple of weeks are looking pretty flat and quiet. There’s a real gap from now until the end of July, with nothing really worth paddling out for. The first real chance of anything rides in on the morning of Friday the 31st of July, so we’ve got a solid stretch of very small, weak conditions to get through before that.
Onemana is the only spot on the cards. The water temp is sitting at 59°, which is about average for this time of year, so no surprises there.
Alright, let’s start with the first proper recommendation. Friday morning, the 31st of July. There’s a bit of life in the water with a 3ft swell coming out of the SE, but it’s a short period windswell around 5 seconds, so it’ll be a bit crumbly and messy. The wind is light and offshore from the WSW, so the surface should be clean. The combined energy is moderate at 105 (moderate wave energy). It’s not going to be pumping, but it’s surfable if you’re keen for a session. The break is fairly exposed, so it’ll pick up what’s on offer.
Then Tuesday afternoon, the 1st of August, things get a bit more interesting. The combined energy jumps up to 184 (moderate wave energy), with a 1ft swell from the ENE, but the period is a sweet 15 seconds – that’s a proper groundswell. That long period will give the waves some shape and power, but at a beach break like Onemana, it might break a bit too straight. Still, with glassy conditions and a light offshore wind, it’s the cleanest window we’ve seen. The swell is small, so it’s fine for all levels.
The only real standout in this whole run is that Tuesday afternoon on the 1st of August. It’s not a big swell, but the quality of the swell and the glassy wind make it the pick of the fortnight. The direction is a bit off the optimum for the break (which is NE), but the conditions are clean enough to make it work. Crowds are sometimes an issue here, so you might have a few others with the same idea.
Overall, it’s a lean run. Nothing to get excited about until the end of the first week of August, and even then, it’s small. But that Tuesday arvo glass-off is worth a look if you’re desperate for a wave.

Information about the Onemana Surf forecast
The above surf forecast table for Onemana provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Onemana can be found by selecting the local surf guide option on the grey menu. Our Onemana 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 (Onemana) 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 Onemana 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.
Onemana is 64 km (40 miles) from Tauranga. If you plan a holiday in The Coromandel, look for hotels and other accommodation in Tauranga. Tauranga has rooms for a wide range of budgets as well as car hire and transport links.
