Table - best surf conditions forecast for Ohara over the next 16 days.
Hey, Rusty here. Let’s run through what Ohara’s got cooking.
The water’s 73°, which is a bit cooler than normal for this time of year – about 3°F off. You’ll feel it.
Wednesday the 8th is a no-go. 7ft swell from the southeast, 16-second period, but cross-onshore wind makes it messy. Big energy (2473) but not worth it.
Thursday the 9th turns the corner. 6ft swell, SSE, 14 seconds, and clean offshore wind in the afternoon. Good for experienced surfers.
Friday the 10th is the standout. 7ft to 7ft south swell, 16-second period, and offshore wind all day. Energy’s pumping at 2568. Clean, powerful, and lined up.
Saturday the 11th keeps the fire. 7ft south swell, 17-second period, offshore wind. Energy peaks at 2962. Expert-level stuff.
Sunday the 12th eases. 6ft in the morning, then 5ft in the afternoon with better wind. Still decent.
Monday the 13th and Tuesday the 14th go small – under 3ft, weak energy. Offshore wind keeps it tidy, but it’s tiny.
Wednesday the 15th brings a pulse: 6ft, SSE, 14 seconds, light offshore wind. Clean.
Thursday the 16th through Sunday the 19th gets choppy and blown out. Even with bigger swell on the 19th (7ft, 2610 energy), the wind ruins it.
Monday the 20th: huge 13ft swell from the ESE, 15 seconds, energy at 7948. Too big for Ohara, and cross-onshore wind. Experts only.
Tuesday the 21st: morning is glassy – zero wind – with 12ft swell. That’s expert territory. By the afternoon, the swell drops to 8ft and the wind turns offshore. That afternoon session is a true standout – clean, powerful, and the best long-range call.
Wednesday the 22nd and Thursday the 23rd go back to messy, choppy conditions.
Bottom line: Friday the 10th and Saturday the 11th are your top picks this week. Tuesday the 21st afternoon is the long-range gem, but it’s two weeks out so keep an eye on it.
Ohara doesn’t break often, so when it lines up, you go.
Rusty.

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.
