The Lowdown

Alright folks, Rusty here. Looks like we’ve got a wild 16-day stretch ahead for Ohara, but don’t get your hopes up too early. The first week is going to be a write-off for any decent paddle surfing, with the real action not showing up until the tail end of the period.

The pattern starts with a massive pulse of energy from the southeast. That swell is going to be huge, but it’s coming in with nasty cross-onshore winds all weekend and into the middle of next week. The water temp is sitting at 80°F, which is about average for this time of year, so no surprises there.

The real standout, and the only window worth talking about, is the morning of Thursday, August 6th. The wind swings around to a gentle cross-offshore breeze from the ESE, cleaning things up nicely. The swell is still a massive 12 ft, which is expert-only territory, coming from the SSE with a very long 15-second period. The combined energy is a massive 5816 (strong). The guidance says this break is inconsistent, so you’ll want to be patient. But for those with the skills and the nerve, this is the one clean shot at a heavy, powerful wave in the whole forecast. The afternoon of the 6th also looks clean, but with the same size, it’s still only for the brave.

After that, the winds go back onshore again for a few days, making a mess of the dropping swell. The next possible window is the afternoon of Tuesday, August 11th, when the wind goes light cross-offshore again. The swell will have dropped to 7 ft from the east, with a moderate 12-second period. The commentary says it’s excellent for experienced surfers, but it’s a marginal call compared to that Thursday session. The combined energy is 1677 (moderate). Still, a clean, manageable wave if you’re an intermediate looking for a go.

The rest of the period from the 12th onward is a long, flat, and choppy gap with no real recommendations. The swell stays small and the wind is mostly onshore, so you’re looking at a blank run of about 5 days. It’s not unusual for this area to have these quiet stretches.

If you’re a kite surfer, the first week with the massive swell and strong cross-onshore winds will be a blast, but for paddle surfing, the only date to circle on the calendar is Thursday, August 6th, at Ohara.

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.
