The Lowdown
Righto, let's have a look at what's on the table for Ohara. Gotta be honest with ya, the first week and a half is a bit of a write-off for any decent paddle surfing. There's a long gap from now, with nothing worthwhile until we start seeing some cleaner conditions creeping in around the 12th of September. Even then, it's very small for a while.
The main event, if you can call it that, is a massive pulse of swell that hits on Monday the 7th of September, but it's a double-edged sword. The wind is offshore and clean from the south, which is *perfect* for the break, but the swell is way too big. We're talking 13ft from the SE with a solid 10-second period and combined energy of 3962 – that's some serious grunt. That's expert-only, and frankly, it's predicted to be too big for the break altogether. The next day, Tuesday the 8th, is much the same story: 12ft swell with offshore winds in the morning, but it's still well into the "too big" zone. After that, it drops quickly.
So, for the best of what's actually surfable, you're looking at the second week. There’s a tiny window Sunday the 13th of September. It's small, with a 3ft swell from the ESE, but it's a proper groundswell with a 13-second period and clean, offshore winds from the SSW. Combined energy is a modest 321, but it'll be clean and shapely. The water temp is sittin' around 79°, which is about average for this time of year, so no surprises there.
The real standout, and the only one I'd get excited about for a normal session, is really that Sunday the 13th. It's consistent enough but just small. If you're a beginner, keep an eye on the 14th and 15th of September, where it stays tiny (2ft) with glassy or light offshore winds, but the water will be like a lake. It's not worth the paddle for any experienced surfer, but for a newbie on a foamy, it'd be alright. The rest of the window is either blown out with onshore winds or too big. A few of those afternoon sessions on the 7th and 8th with the huge swell and offshore wind are purely for the brave or the stupid.

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.
