The Lowdown
Alright folks, Rusty here. Let's have a look at what Ohara has in store for us over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. We’ve got a real dry spell from now through the end of July and into the first day of August. There’s just nothing worth paddling out for—small, weak, choppy junk. Tuesday the 28th has a brief moment of clean offshore wind in the afternoon with tiny 3 ft swell, but it’s barely surfable. You’re better off waiting.
Then, things finally get interesting. Sunday, August 2nd is where it’s at. The morning is glassy with a solid 3 ft SE groundswell, long period of 16 seconds, and the combined energy is pumping at 544. That’s moderate energy, and with the glassy conditions, Ohara is going to be clean and lined up. The afternoon holds well too, with a clean cross-off breeze and 4 ft SE swell. This is the standout window—small but perfect, and the kind of day you don’t want to miss. Keep in mind crowds are possible here.
Monday the 3rd sees the swell building to 6-6 ft from the SE, still with that long 16-second period, but the wind is side-shore and the conditions are just marginal. It’s still worth a look if you’re keen, but Sunday is the real gem.
Beyond that, we get a monster pulse. From Tuesday the 4th through to the 9th, it’s just too big for most. The swell hits 10 ft and climbs to a massive 21 ft by the 7th, all from the SE. The combined energy goes through the roof, hitting five-digit figures (5673 up to 26349). That’s very strong energy. The wind is mostly cross-onshore or howling, so it’s messy and dangerous. This is expert-only and honestly, looks more like a kite or tow-in show than a paddle session. Beginners, stay well clear.
By the 10th and 11th, the swell drops back to 7-8 ft, but the wind is howling offshore at 25 mph, making it clean but a real battle to get out. Not for the faint-hearted.
So, bottom line: your best bet is Sunday, August 2nd, with that glassy, clean 3-4 ft SE groundswell. Get in the water. The rest of the window is either flat, too big, or too windy.

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.
