The Lowdown
Alright, Rusty here, let’s break down what’s coming up.
Honestly, it’s gonna be a slow start. The first real swell doesn’t show up until the 16th of September, and even that’s nothing to write home about. For the first week and a half, we’re dealing with tiny waves and mostly poor conditions, so don’t rush to wax up. Water temp is sitting around 59°, which is about average for this time of year.
The standout window is Monday the 21st of September. Onemana gets a solid 6ft to 7ft NNE swell, with a moderate offshore breeze in the morning and a fresh offshore in the afternoon. That’ll keep the waves clean and lined up. The combined energy jumps to 409 and then a big 1178, so there’s serious power behind it. The period is 8 to 11 seconds, so you’re getting good shape and push. That afternoon session on the 21st is the best of the whole run – but with waves over 6ft, it’s for experienced surfers only. Fresh offshore wind will keep the faces glassy.
Before that, we get a pulse on the 16th – about 5ft to 5ft from the NW with a short period of 6 to 7 seconds. It’s offshore in the morning but the quality is marginal, so it’s more of a heads-up than a must-paddle session.
The rest of the forecast is mostly flat or weak. A few mornings on the 19th and 20th offer up knee-high windswell with light winds, but it’s pretty ordinary. You’re better off waiting for that Monday the 21st.
Hang tight, keep an eye on that 21st, and remember – forecasts can shift, so check back in.
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.
