The Lowdown
Alright, let’s break it down for Onemana. The whole 16-day stretch is a tough one. The first time you’d even think about paddling out is Monday the 27th of July, and the week before that is a total write-off – a six-day gap with nothing happening.
Water temp is about 15°, normal for this time of year.
The only real highlight, and it’s a small one, is Monday morning the 27th. Onemana has a clean offshore breeze from the west at 6 mph, with a tiny 1ft swell from the ESE. The period is a nice, long 13 seconds, so it’s proper groundswell. The energy is low (59), but the wind is offshore, so the surface will be clean. It’s a fairly consistent spot, but this is a long-period groundswell on a small wave – it’ll be weak and hard to get a decent ride on. It’s the best of a bad lot.
Tuesday the 28th is similar, with a 1ft ESE swell, 12-second period, and clean conditions with a light cross-offshore breeze. Energy is still low (55).
By Wednesday, the swell drops to 1ft, and the rest of the run stays tiny. The second week of August has a tiny bump on the 4th, with a 4ft swell from the north, but the wind is a messy cross-shore at 12 mph, and on the 4th afternoon it’s a cross-on with 5ft from the NNW. The energy is moderate (129 and 180), but the onshore breeze chops it up. It’s all poor surf conditions. For the entire 16 days, there’s nothing that’s going to get you out of bed.

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.
