The Lowdown
Alright, let’s talk about Ohara. It’s been a slow couple of weeks, with a lot of small, weak chest-high slop for the first ten days. The swell is mostly from the east and southeast, but the energy is low – combined energy in the low hundreds to mid-hundreds, which is just a little bump. The wind is a mix of sideshore and side-offshore breezes, nothing that’s going to make it look good. The real change comes on Thursday morning, July 31st. The period jumps to 17 seconds, and the combined energy hits 238. That’s a proper groundswell from the east-southeast. The wind is light offshore from the south-southeast, so it’ll be clean. That Friday morning is the first real window – it’s only about 2ft, but with that long period and clean wind, it’ll be lined up and fun.
Then, things get serious. On August 1st, the swell pumps up to 6ft from the east-southeast with a very long 17-second period. The combined energy is 1843. That’s a massive jump in power. The wind is a bit of a bummer – cross-on from the northeast at 9 mph, so it’ll be a little bumpy. It’s still manageable for intermediates. The biggest day hits on August 3rd, with the swell predicted to reach 10ft from the east-southeast and an 18-second period. The combined energy is a staggering 4660. That’s a clean, powerful, and very large groundswell. The report says it’s predicted to be too big for this break. The wind is also cross-on, making it a messy, dangerous beast. That’s for experts only. The best window of the whole run is Tuesday, August 4th. The swell has dropped to a solid 8ft, the period is still a strong 16 seconds, but the wind swings to the southeast at 6 mph, giving us a clean, side-offshore breeze. The combined energy is 2629, which is still very strong. The conditions are described as excellent for experienced surfers. That Tuesday afternoon, and into Wednesday morning with the swell easing to 6ft and the wind staying light and offshore or cross-off, is the best on offer. Clean, powerful, east swell wrapping into Ohara.
Because Ohara is an inconsistent spot, this long flat spell is pretty normal. But when that long-period groundswell finally shows up, it’s worth the wait. Water temp is around 77°, right about average for this time of year.

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.
