The Lowdown

Alright, let’s break it down. Ohara’s been trying to get its act together, but most of this run is a bust. The first real light at the end of the tunnel is Wednesday 27 August, and that’s where you need to focus.

The water’s a warm 82°, which is about 2° above the usual for this time of year – nothing crazy, but you’ll notice it when you’re sitting in the line-up.

The early part of the forecast is a long, slow burn. From Wednesday 12 August through to Monday 25 August, it’s a stretch of flat, messy days. Yeah, there’s swell – we get a spike to 8ft on Sunday 16 August with combined energy of 2696 – but the wind is cross-on and choppy, wrecking any chance of clean waves. There’s a few days with a cross-off breeze, but the swell is too small to care about. You’d be better off waxing your board and waiting.

The real standout is Wednesday 27 August. Thursday morning, the wind goes glassy, and we’ve got a 6ft swell from the ENE with a period of 7 seconds. That’s a short period, so it’ll be a bit fast and lumpy, but the combined energy of 391 is enough to push through some fun, punchy little waves. The key is the wind – glassy, zero. That means clean, smooth faces, no bump. It’s not a big groundswell, but at a beach break like Ohara, it’ll be plenty rideable. Then Thursday afternoon, the wind swings to a gentle offshore from the south, and the swell ticks up to 6ft with 418 energy. That’s the best of the whole forecast. The offshore breeze will hold the faces up, and with the ENE direction, it’s got some shape.

Now, a heads-up: Ohara is inconsistent, and crowds can be a thing sometimes. But on a day with glassy conditions and a clean 6ft, you’ll regret not showing up. Go for the morning glass, or the afternoon offshore. That’s the one.

The rest of the run after that? Monday 25 August has a clean offshore morning but only 2ft – not enough to get excited about. Tuesday 26 August has a glassy afternoon with 2ft, but it’s weak. And then Wednesday 27 only gets one good morning before it fades back to small stuff.

Bottom line: if you’ve got the patience to wait, Wednesday 27 August is the day. Clean, glassy, decent energy. Don’t expect anything before that.

Information about the Ohara Surf forecast

The above surf forecast table for Ohara provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ohara can be found by selecting the local surf guide option on the grey menu. Our Ohara 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 (Ohara) 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 Ohara 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.
