The Lowdown
Alright, let’s get into it. The surf’s pretty quiet to start, but there’s a glimmer later on if you’re patient.
The first real surf on offer is this Wednesday morning, July 15th, at Ohara. It’s tiny—just 2 ft of swell from the south, with a period of 10 seconds. The wind’s gentle offshore from the south, so it’ll be clean enough, but the energy’s weak (110) and the waves are ordinary. Not worth getting excited about. The afternoon stays similar, with a bit more wind.
Thursday morning, July 16th, is the first little highlight. The swell bumps up to 3 ft from the east-southeast, and the wind goes glassy—dead calm. That’s rare, and it’ll make for some clean, if small, waves. Energy’s moderate (152). The afternoon gets a moderate offshore breeze, still clean.
Friday the 17th through Sunday the 19th stays in the 3 ft to 3 ft range, mostly from the east or east-southeast, with periods around 9 seconds. Winds are light offshore or cross-offshore, so conditions stay clean. But the waves are still just ordinary—nothing to rush for. The energy sits in the moderate range (150–195).
Monday the 20th and Tuesday the 21st: Monday’s a write-off with poor conditions, but Tuesday morning, July 21st, is a genuine standout. Swell hits 3 ft from the east at 10 seconds, and the wind is glassy again. The combined energy is solid (200), and the forecast says “expect good surf conditions.” That’s your best early window—clean, small, and fun for an intermediate.
Wednesday the 22nd turns messy with cross-onshore wind and poor surf, then Thursday the 23rd morning shapes up again: 3 ft east swell, 10 seconds, light cross-offshore wind, and clean. Energy’s up to 268. Another good session.
The end of July and into the 30th sees a big change. Around Monday the 27th, the swell direction swings to the southeast, and by Wednesday the 29th, the period jumps to 19 seconds—a very long-period groundswell. That’s a double-edged sword at a beach break like Ohara; it can be too straight and hard to catch. But the energy is massive (1012) and the waves are 3 ft to 6 ft. The real standout is Thursday morning, July 30th: 8 ft from the south-southeast at 16 seconds. That’s big, powerful, and only for experienced surfers. The wind is light offshore, so it’ll be clean. Combined energy is a whopping 3660. This is the best of the whole forecast, but it’s over a week away and less certain.
Ohara is inconsistent, and this run shows it. There are gaps of a few days with nothing worth paddling out for. The water temperature is about average for the 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.
