The Lowdown
Right, let’s break down what’s coming up at Ohara over the next couple of weeks.
Honestly, the first few days are a real dud. Saturday the 25th and Sunday the 26th kick off with swell barely hitting 2 to 3 feet, and the wind is mostly cross-onshore or light cross-shore. The water’s sitting at 79°, which is pretty normal for this time of year. The combined energy is weak (93 to 247), and the wave comments say “poor” or “marginal”. Nothing to get wet for.
From Monday the 27th through to Friday the 2nd of August, it stays flat and ordinary. Swell stays between 1 feet and 3 feet, with a few pockets of offshore wind (like Sunday afternoon and Thursday afternoon) giving cleaner conditions, but there’s just no power. Energy readings stay low (32 to 128), and comments stay “poor” or “very ordinary”. Not worth a paddle.
But hold up—Sunday the 2nd of August is the one to circle. Sunday morning shows a clean 3-foot SE swell with a 10-second period, light cross-offshore wind, and moderate energy (291). The comment says “expect good surf conditions”. Sunday afternoon gets even better: 2 feet of swell, but with a sweet 16-second period, clean offshore wind from the S at 9 mph, and combined energy of 394. For a break that’s inconsistent, this is a proper little gem. The swell direction is straight out of the SE, which is what this spot wants, and it’ll be glassy. This is the standout window.
Monday the 3rd of August ramps up to 6 to 7 feet of SE groundswell with 16 to 17-second period, but the wind turns cross-onshore, making it lumpy. The energy is huge (1688 to 2656), but the chop will put off all but the keen ones.
From Tuesday the 4th onward, it’s a monster. Swell hits 8 feet, then 10 feet, then 15 feet, and by Friday the 7th it’s a full-on 28 to 41 feet with gale-force onshore winds. Combined energy readings like 57516 and 151477 tell you this is flat-out dangerous for paddle surfing. Even Saturday the 8th and Sunday the 9th still have 10 to 15 feet of leftover swell with cleaner wind, but it’s way too big for most.
So to sum it up: the first week is flat and forgettable. Your best shot is Sunday the 2nd of August—small but clean, good period, and that offshore wind. After that, it’s either messy or way too big. This spot is inconsistent, but when it lines up, it’s worth it.

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.
