The Lowdown

Alright, let's get down to it.

Truth be told, the next stretch is looking pretty grim. It's flat, weak, and will have you checking your leash for rust. We’ve got a solid block of days where the swell is just not there. It’s not going to be worth dropping everything for, that's for sure. The good news is the wind is often offshore, so it will be clean, but clean and tiny is still tiny.

There’s a little pulse of activity on the morning of Thursday, September 10th. We’re looking at a `1ft` NE swell with a long 14-second period. The energy is weak at `68`, but the WNW wind is offshore and the surface is glassy. It’s surfable, but you’re going to want a high-volume board. It's the kind of day for longboard fun, not for pulling into pits.

The rest of that week is more of the same. Small swell and a lot of cross-offshore winds through Friday and the weekend, which will add some texture. The following Monday and Tuesday have lighter winds and clean conditions, but the swell is down to a tiny `1ft`. The water temp is about average for the time of year, so no drama there.

We’re in the doldrums for most of the second week, too. The energy is low and the swell stays minimal. The first real sign of life comes on the morning of Wednesday, September 23rd. The swell bumps to `2ft` with a short 8-second period, and the energy climbs to a moderate `73`. It’s still small, but with a clean offshore wind, it's the best thing we’ve seen in a while. The next day, Thursday the 24th, holds that size with even lighter winds, so there could be a few fun ones if you're happy to grovel.

Then, on Friday the 25th, we finally see a little more juice. The swell pushes to `3ft` and the energy jumps to `184`. It’s the most on offer for the whole forecast period, but don’t go booking a flight. It’s still small and nothing to get crazy about. This whole stretch is a groomer’s playground, not a surfer’s paradise.

That's all I've got. Stay patient.

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.

Onemana is 64 km (40 miles) from Tauranga. If you plan a holiday in The Coromandel, look for hotels and other accommodation in Tauranga. Tauranga has rooms for a wide range of budgets as well as car hire and transport links.
