The Lowdown
Alright, this is Rusty, and I'm taking a look at the Ohara forecast. Let's be straight with you – the opening stretch here is pretty ordinary. We’re looking at some inconsistent, weak swells coming in from the east and southeast. The surf is small, mostly 1ft to 2ft, and the winds, while often light, are cross-shore or cross-on, keeping things messy. The combined swell energy is very low to moderate, ranging from 21 to 267. There’s nothing to get excited about through the first week.
However, as we head into the start of August, the story changes in a big way. A long-period groundswell is forecast to arrive. The first real standout moment looks to be the afternoon of Saturday, August 1st. We’ve got a decent 2ft swell from the ESE with a very long 13-second period, clean conditions thanks to a light cross-offshore wind, and the combined energy is hitting 267. It’s not huge, but for Ohara, that’s the most refined wave we’ve seen in the window.
Then, hold onto your board. From Sunday, August 2nd through Wednesday, August 5th, we get a significant pulse of groundswell. The swell size jumps to 5ft on Sunday morning and peaks at 8ft on Monday afternoon. This is powerful stuff, with a very long period of 16 to 18 seconds and combined energy readings over 1000, peaking at a massive 3924. This is expert-level stuff – too big for beginners, and even experienced surfers need to be wary. The trade-off is that the winds aren't perfect; they're mostly cross/onshore, so it won't be pristine. The long period means these waves will have a lot of push and will be better suited for a point or reef than a beach break, but keep in mind it’s a bit uneven.
After that big swell drops off, things settle down again. Towards the tail end of the forecast, on Thursday, August 6th, we get a clean-up. The afternoon shows a glassy 2ft from the east with a clean offshore wind from the south, making for good, clean conditions (combined energy 269). It’s a nice way to finish the forecast period, but nothing compared to that massive August 2nd-5th window.
Overall, the best bet is the clean, small-ish swell on the afternoon of Saturday, August 1st for some fun, user-friendly waves, or the big, powerful groundswell from August 2nd onwards for the experienced crew willing to deal with some chop. There’s a lot of waiting for those few standouts.

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.
