The Lowdown
Alright, grab a coffee and sit down. This is a tough one.
Look, I’ve been staring at the charts for Onemana, and I gotta be straight with you – it’s a long, flat, frustrating run ahead. We’re starting now and looking out over the next 16 days, and the honest truth is, there’s not a single session worth paddling out for. The whole 16-day window is a write-off. Nothing is on the cards.
The wave energy is a joke. On Monday the 31st of August, we’re looking at a weak 2 ft NE windswell with a combined energy of just 52 – that’s barely a ripple. It’s clean with a fresh offshore breeze, but that's like putting a fresh coat of paint on a wrecked car. The swell is just too small. The water temp is sitting at 59°, which is pretty standard for this time of year.
From there, things just get worse. Tuesday the 1st of September, Wednesday the 2nd, Thursday the 3rd – it’s the same story. Tiny, weak swells of 1.0 ft to 0.7 ft. The wind is good, mainly offshore or cross-off, but it doesn’t matter. We’re in the doldrums. The energy drops from 52 down to a pathetic 12 by Thursday afternoon. It’s a desert out there.
We go through the whole first week, and each day is a carbon copy of the last. A few days of glassy conditions on the 5th and 6th and even a little glass-off on the morning of the 15th of September, but the swell is still 0.7 ft. It’s cruel. There’s a bit of a bump on the 11th of September when the combined energy hits 145, but that’s from a short-period, 3 ft SSE windswell with a pitiful 5-second period. It’s cross-onshore and choppy. That’s not surf, that’s a washing machine. A kite surfer might get a grin out of it, but for a paddle surfer, it’s a no-go.
The entire forecast is a string of zeros. Every single entry is flagged as “poor surf conditions.” This isn’t a lull; it’s a full-blown flat spell. For an area like Onemana, which is a fairly consistent beach break, this is a dry spell. It’s one of those times where you just have to walk away, wax your board, and wait for the charts to change. Don’t hold your breath.

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.
