The Lowdown
Alright, Rusty here again – this time in inches and feet for you imperial folks.
Let’s be straight: Onemana is in a flat spell. Water temp is 59°F, right about normal for the season, so no surprises there. Starting Thursday 3rd and running through Sunday 6th, we’re looking at barely 0.7ft waves – ankle-biters. It’s a long wait for the only real event.
That comes Monday 7th. The morning bumps up to 8ft from the NNW, a short 8-second interval, with moderate energy (1119). Wind is light out of the NW at 15 km/h, cross-off, keeping it clean. That size is only for the experienced crew. By Monday afternoon, it settles to 6ft, still NNW, now with a clean offshore from the W at 15 km/h, energy strong (645). The conditions are good both sessions. If you can handle the size, this is your window.
Tuesday 8th drops to 3ft but it’s just ordinary. Wednesday 9th goes back to 0.7ft, with a long 15-second period but no energy (44) – even the glassy afternoon won’t save it. From Thursday 10th onward, it’s a desert: 0.7ft to 2ft, occasional offshore breezes and glassy spells, but nothing you can really surf. A few afternoons look perfect and flat – cruel.
The second week offers no hope. The standout is Monday 7th. Everything else is a flat, long wait.
Rusty.

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.
