The Lowdown
G’day, Rusty here. Look, I’ll level with you – this 16-day outlook is a lean one, no two ways about it. The first stretch is almost completely flat. We’re talking swell heights barely above 0.2m to 0.3m, combined energy sitting weak, often below 40, and nothing with any grunt. There are some glassy moments, especially around Monday the 14th and Tuesday the 15th when the wind goes slight, but there’s no wave to ride. You’d be bobbing around on a flat day.
The one real pulse of life shows up on Friday the 18th. The morning brings a 1.5m swell with a 7-second period, and the energy finally climbs into the moderate range at 252. By the afternoon, the wind goes glassy, the swell settles to 1.3m, and the energy pushes up to 270. That’s the clear standout of the whole window. It’s clean, it’s got some push, and even though the period is short, it’s the best you’ll see. Onemana is fairly consistent, so it’s worth paddling out for that session.
Saturday the 19th offers a bit of a follow-up – 1.1m in the morning with offshore winds and moderate energy at 183 – but it fades quickly. By the afternoon the swell drops to 0.9m, and the wind picks up, so it’s all downhill from there. After that, from the 20th onward, it’s flat out. Swells stay under 0.6m, periods are jumbled, and energy readings fall back to single digits or low 20s. Winds go onshore and cross, and we even see some rain and chop around the 24th and 25th. Nothing but dribble through to the 28th.
So, bottom line: if you want a wave, make it Friday the 18th afternoon. That’s the pick of the bunch. Saturday morning is okay but not special. The rest is a flat, frustrating stretch, and that’s normal for this area when it goes quiet. No need to rush out otherwise – this one’s a dry spell.
Keep the fins dry, boys.
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.
