The Lowdown

Alright, let’s get into it. The surf window ahead has a little pulse of something decent early on, but it fades out fast, and then we’re waiting over a week for things to possibly fire up again.

Monday the 24th is where it’s at. Ohara’s looking clean with that clear sky and a light cross-off breeze. Swell is a solid 3ft from the SSE, but check out the period – 18 seconds. That’s proper groundswell energy, pushing the combined energy up to 944 (moderate). Water temp is sitting around 82°F, about a touch warmer than normal for this time of year, so it’s a comfortable one. The sets will be well-spaced and punchy, making paddling out a bit easier, but at a point like this, those long lines should bend in real nice. Crowds are possible, but with inconsistent conditions, it might not be a zoo. That afternoon still has some push at 6ft (combined energy 1836), but the wind picks up to 15 mph and quality drops off – better to get on it early. By Tuesday the 25th, the morning has 6ft waves, but that fresh 19 mph cross-off wind is gonna knock the shape around, and the period drops to 13 seconds. Not the same feel.

Then we hit a dry spell. From Wednesday the 26th right through to Sunday the 30th of August, it’s mostly poor or marginal. Swell drops below 3ft, short periods, and the wind turns cross-on or onshore. Not worth paddling out for – a solid 5 days of flat to messy junk.

Things perk up a little on Monday the 1st of September. Morning has clean 3ft waves from the ESE with 11-second period – combined energy is 246 (weak) and a light cross-off breeze. It’s surfable, but nothing to write home about. That modest trend continues into Tuesday the 2nd, but with tricky winds and a risk of t-storms, it’s still very low-key.

Here’s the standout to keep an eye on: Saturday the 5th of September. The morning shows a jump to 6ft from the ENE, period at 9 seconds, and combined energy hitting 1050 (moderate). The wind is cross-shore, so there’s some chop, but the clean afternoon session with 5ft waves and a gentler cross-off breeze could be the best of the whole second week. This one is a promising call for an intermediate crew – but it’s still a week and a half out, so treat it as a hopeful but not locked-in bet.

After that, Sunday the 6th looks too blown out with strong offshore winds at 25 mph, making it hard to paddle and pretty hostile. The rest of the run into Tuesday the 8th fades back to poor conditions with onshore wind and lumpy sea.

Overall, grab Monday morning, pencil in that Saturday the 5th session, and wait out the rest.

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.
