The Lowdown
Alright, let’s check the outlook for Ohara over the next couple of weeks. It’s a bit of a waiting game, with some good windows if you’re patient. The first real chance to surf doesn’t show up until later on.
The water temp is 79°, which is about normal for this time of year, nothing unusual.
We start on Thursday the 3rd with tiny, weak surf – 2ft from the east at a so-so 10 seconds. The combined energy is weak (252), and the cross-off wind is okay but it’s just not doing anything. The rest of that day and into the weekend gets worse: Friday the 4th is a write-off with poor conditions and onshore wind. Saturday the 5th sees a bump in size, up to 6ft, but that’s a short-period 6-second windswell with a fresh onshore, making it a lumpy mess. Sunday the 6th is even bigger – 8ft to 8ft – but it’s strong onshore and messy. Honestly, if you’ve got a kite, those days might be more interesting than trying to paddle.
Monday the 7th is still big and messy, though the wind swings offshore in the afternoon (28 mph from the south). It’s clean, but with 7ft and that stiff breeze, it’ll be hard work just to get out the back.
Now, here’s the standout of the whole forecast, and it’s a week away on Tuesday the 8th: the swell is huge – 13ft in the morning, 12ft in the afternoon – from the south with a 10-second period. The combined energy is massive (6273 and 3719). The wind is cross-off and clean, and the forecast notes say the wind and tide are favorable. But look, this is way too big for anyone but an expert. This is a serious, heavy swell for Ohara. If you’re not a pro, sit this one out on the beach.
Wednesday the 9th is still solid at 8ft from the SSE, and the wind turns offshore in the afternoon, giving us clean, punchy waves. It’s still big for a beginner but a good option for intermediates who are comfortable. Thursday the 10th drops to 6ft to 7ft with clean conditions – a decent couple of days if you can pick your tide.
Then we hit a gap: Friday the 11th is small and glassy in the morning (4ft, calm wind), but the swell is weak. Saturday the 12th and Sunday the 13th are poor with onshore wind and messy surf, though Sunday afternoon cleans up. Monday the 14th has a glassy afternoon with 4ft from the SE – that’s a nice little session if you’re free.
The real second standout comes on Thursday the 17th. The morning shows 5ft from the south at a long 11 seconds, glassy conditions, and a combined energy of 602. The forecast says “expect very good surf conditions” – that’s the best rating we see. It’s a proper groundswell with clean glass, perfect for a point break or reef setup. Ohara is exposed, but that long period should produce some nice lines. Crowds are possible here.
Friday the 18th fades out with small, weak surf.
So, your best bet: if you’re an expert, Tuesday the 8th is the biggest, most powerful day, but it’s serious. For everyone else, the morning of Thursday the 17th is the pick of the forecast – clean, head-high groundswell with glassy conditions. The days around the 9th and 10th are also solid if you can handle a bit of size.
Stay safe out there.

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.
