The Lowdown

Alright folks, Rusty here. Let’s get stuck into what’s going on at Ohara.

First thing you need to know: this stretch is gonna be a real mixed bag over the next 16 days. The water temp is sitting pretty much average for this time of year, so nothing wild there. We’ve got a decent run of swell coming through, but finding the right window with clean conditions is going to take some patience.

The honest truth is, we’ve got a big block of dirty, windy, lumpy surf to sit through first. Starting Saturday the 5th through to the end of the following week, it’s mostly cross-onshore junk with moderate to fresh breezes, short period swell, and poor quality. The combined energy is moderate (209 to 358), but it’s just not worth paddling out for. The swell is there, but the wind is butchering it.

The one real standout, and I mean the only one that gets the blood pumping, hits Monday the 7th. A strong southerly swell pushes in with a 12 ft to 15 ft range and a 9 to 11-second period, creating a massive energy spike (2704 to 4870). The wind goes offshore and clean on Monday morning, which is a beautiful thing. But here’s the kicker, and I gotta be straight with you – that swell is just too big for this break. This is for experts only. The raw power is incredible, but if you’re not a hero, give it a wide berth. The afternoon gets a bit smaller but goes cross-onshore and messy again.

After that, the rest of the first week and into the second is a write-off of poor conditions, onshore breeze, and mostly junk. The second week, starting around the 13th, we see a few glimmers. The morning of the 13th pulls in a clean 6 ft from the ENE with light cross-offshore wind and a short period (7 seconds) – it’s surfable, but the combined energy is moderate (468), and it’s not going to blow you away.

The true late-season treasure shows up on the 15th and 16th. The morning of Tuesday the 15th has clean, 4 ft surf from the ESE with nearly glassy cross-offshore wind. The combined energy is moderate (386), but the conditions are clean. Then Wednesday the 16th… that’s the one for the longboard. We’re talking glassy, light offshore wind, with 2 ft of long-period (13 seconds) groundswell from the east. The combined energy is low (229), but those conditions are perfect. That’s a serious dawny session for the log.

Beyond that, heading into the 19th and 20th, it fades out to tiny, weak waves with onshore wind again. So, the best of the best? That Monday the 7th for the heavy crew only, and the glassy, clean morning of the 16th September for the smooth operators.

Rusty, signing off.

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.
