Table - best surf conditions forecast for Onemana over the next 16 days.
Alright, Rusty here, looking at the same swell charts for you. Got to be honest, it’s a quiet run for Onemana. Most of the next couple of weeks are flat or blown out. There’s a decent shot early on, and then a monster swell at the end that’s more for the kite crew than anyone else.
The only real near-term play is Wednesday, July 8th. Wednesday morning brings a 4ft swell out of the NNE. The water is sitting about average for this time of year, at 60°F. The wind is a cross-shore from the S at 9 mph, so there’s a bit of texture, and the wave energy is moderate at 456. Not perfect, but you can surf it. The real highlight is Wednesday afternoon: the swell inches up to 5ft from the E, the wind drops to a glassy 3 mph from the SW, and it cleans right up. That afternoon session is your best bet.
From Thursday the 9th, it’s a long dry spell. For over a week, the conditions are just poor – small, weak waves with short periods, usually with lumpy onshores or cross-chop. The wave energy drops into the double digits. Not worth paddling out.
Then on Tuesday, July 21st, things get wild. Tuesday morning shows a massive 16ft swell from the ENE. The wave energy is enormous at 8931 – that’s a serious amount of power. The period is 10 seconds, so it has some good energy. But the wind is blowing onshore from the ESE at 16 mph. That much swell with onshore wind at a beach break like Onemana is going to be a total mess. This is a kite surfer’s dream, not a paddle surfer’s. Tuesday afternoon drops to a still-huge 12ft from the NNE with a longer 12-second period, but still with that onshore wind. Wednesday the 22nd drops to 5ft from the E, but it’s still blown out and choppy.
So, the only true standout in the whole 16 days is that glassy Wednesday afternoon on the 8th. It’s small, but it’s clean. For the rest of it, I’d save your energy. The surf stays poor right through to the end of the forecast. Onemana is just not giving us anything this time.
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.
