The Lowdown
Hey folks, Rusty here. Let’s get into the surf forecast for Ohara.
Honestly, the next week or so is a write-off. There’s a long dry spell from now through the end of August and into early September where you’ll find almost nothing but tiny, wind-chopped surf. Figure 7 or 8 days of flat to small junk. Not worth pulling the wetsuit on.
Things finally perk up on Tuesday the 1st of September. The wind cleans up to cross-offshore and a small Southerly swell rolls in at about 3ft. The 11-second period will give the waves some shape, and there’s moderate energy in the water (290). That afternoon session will be quiet and clean, perfect if you don’t mind things being small.
Your best bet in this first window is Wednesday the 2nd of September. We’ve got clean offshore Southerly winds all day with the swell holding steady at 3ft in the morning and a clean 3ft in the afternoon. A consistent 11-second period means lined-up, rideable waves, and the combined energy sits at a moderate 385. For a relaxing, uncrowded surf, this is the pick of the early period.
Then things change in a big way. By Sunday the 6th of September, the swell packs a punch. An SSE groundswell pushes in at 8ft with a very long 14-second period, and the combined energy is through the roof (2752). The wind stays cross-offshore, so it’ll look beautiful, but over 8ft you’re looking at a big, powerful ocean for experts only. It gets even more intense Monday the 7th – a 11ft to 13ft Southerly swell with strong offshore winds and extreme energy (over 3000). Long period, heavy, and raw. That’s a serious swell that’s going to be way too much for most paddlers; honestly, that setup looks more like a kite-surfing day than anything else.
So here's the deal: skip the first week. The real highlights are a clean, fun small day on Wednesday the 2nd, and a massive, expert-only groundswell arriving on the 6th and 7th of September. That far-out one is promising, but mark your calendar and keep an eye on it.
Rusty.

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.
