The Lowdown
Alright mate, let’s talk surf around Onemana. It’s a bit of a tease over the next couple of weeks – a few bright spots, but plenty of flat spells to snooze through too. Water temp is sitting around 58°, which is about what you’d expect for this time of year.
First chance for a wave comes Saturday morning, August 15th. We’re looking at chest-high sort of stuff, around 5ft, rolling in from the east with a short 8-second period. That short period means it’ll be a bit jumbled, but the wind is a light cross-off out of the SSW, so the surface should be clean. The energy is moderate at 403, so there’s some weight to it. Onemana is fairly exposed to the NE, and this east swell works well enough here. It won’t blow your mind, but for a Saturday morning session, it’s a solid go. The afternoon is a touch smaller at 5ft, still clean – worth a look.
Sunday the 16th drops off to around 4ft from the east, period still at 8 seconds. It’s surfable but pretty ordinary. Clean again with a light SSW cross-off, but the energy is down at 170, so it’ll be weak.
Now the bad news – from Sunday afternoon all the way through to early on Tuesday, August 25th, it’s mostly flat or tiny. That’s over a week of knee-high nothingness. You could find a tiny ripple on a few mornings, but it’s not worth paddling out for.
The big standout is Tuesday the 25th. We’ve got a solid pulse of swell – 7ft from the North-Northeast in the afternoon, with a short 7-second period. That’s a lot of water moving, so it’ll be powerful and a bit dumpy – definitely for experienced surfers only. The wind is howling straight offshore from the WSW at 12 mph, so those waves will be clean and hollow. The combined energy is a strong 493. With the swell direction matching the ideal NE and that clean offshore wind, this is the session to wait for. But at 7ft, it’s not for beginners.
Wednesday the 26th morning still has some fun leftovers at 5ft from the NE, still short period at 7 seconds, and clean with a light NW cross-off. Worth a look, but it’s dialled back.
After that, it fades into tiny surf again to close out the month.
Bottom line: be patient and aim for Tuesday the 25th afternoon. That’s the one.

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.
