The Lowdown

Alright, let’s switch to feet and miles. Rusty here.

So, for Ohara, we’re looking at a slow start. The first week is mostly small, choppy junk with winds that are either cross-off or onshore. A few tiny windows, but nothing that gets the blood pumping. It picks up as we move into September.

Tuesday 26 August morning – there’s a little 3ft SSE swell with a 10 second period. Light cross-off wind from the WSW keeps it clean, but the combined energy is weak. Surfable, but not special. The rest of that week is mostly poor conditions.

We go through a dry spell until Monday 1 September. That morning, we get a solid SSE swell at 3ft with a nice 12 second period and a light south offshore wind. Clean lines, moderate energy reading. But the real standout is Tuesday 1 September afternoon. The swell pushes to 4ft from the east on that same 12 second interval. A gentle 15 km/h SSE offshore wind makes for clean, shapely waves. That is the session to aim for.

Remember, Ohara is an inconsistent break, so it won’t be packing up every set, but when the good ones come, they’ll be worth the wait. The water is a warm 82°, a touch above average, so it’s summer conditions.

Looking into the second week, the size goes up, but the wind quality drops. Sunday 6 September morning has 5ft from the SSE at 12 seconds – big energy (855). But it’s a gentle cross-shore, not glassy. That long period groundswell might race a bit too straight on the beach. Monday 7 September morning brings a chunky 7ft SE swell at 9 seconds – that’s expert territory. The cross-shore wind will make it lumpy. With that much size and messy wind, it might be better suited for kite surfing than a standard paddle session.

Tuesday 8 September has 6ft from the south with a short period – junky and cross-shore.

The clear winner is Tuesday 1 September afternoon. Mark 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.
