The Lowdown
Alright, Rusty here. Let's talk about the next couple of weeks, and it's a mixed bag.
We've got a proper swell coming in on Thursday morning, August 6th, at Ohara. It's a solid 7ft from the SSE with a 13-second period, packing some serious energy. The water is 78°, which is a bit cooler than usual for this time of year, but nothing crazy.
The problem is Thursday morning has a cross-on wind, making it choppy. But by Thursday afternoon, the wind swings clean cross-off, and the waves get glassy. That's the session to aim for. The 7ft swell is solid, on the edge of big for some, but with that offshore wind, it's going to be a treat for experienced surfers. The swell comes from the SSE, a bit off the preferred SE, but the clean wind makes up for it. Remember, it's an inconsistent break, so you'll be waiting for the sets, but they'll be worth it. Crowds are possible.
Friday, August 7th, keeps it going. The swell drops a bit to 6ft from the S, but the period stays at 12 seconds, and the energy is still strong. The wind is cross-off in the morning, turning pure offshore in the afternoon. This is clean, excellent surf all day. Saturday, August 8th, the swell backs off to 4ft in the morning with light cross-off winds, offering clean, smaller waves. The afternoon sees a bump back to 4ft from the ESE with a 13-second period, cleaning up nicely.
Sunday, August 9th, the swell is around 6ft from the ESE, but the wind turns cross-shore, bringing a bit of chop. Still surfable, but not as perfect. Then, from Monday, August 10th, all the way to August 21st, it's a long, dry spell. The wind is onshore, cross-on, or just plain messy, creating lumpy, choppy conditions. The swell hangs around, mostly between 3ft and 6ft, but the wind ruins it. For about two weeks, it's a complete write-off for decent paddle surfing.
The clear standout is Thursday afternoon, August 6th, through Friday, August 7th. That's your window. Don't sleep on it.
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.
