Alright, surfers, Rusty here. Let’s chew the fat about what’s cooking at Ohara.
The outlook starts flat, but be patient. A proper pulse of strong, long-period groundswell is set to roll in from late around Monday the 6th, turning on some serious waves through the middle of next week and into the following weekend. The water is sitting at a notable 72°, which is a touch colder than we’re used to for this time of year.
We kick things off on Saturday the 4th with small, weak energy. It’s surfable but very ordinary with light cross-off winds.
Sunday the 5th is a write-off with poor conditions and tiny swell.
Then things get interesting. Monday morning the 6th sees a jump in energy and a clean cross-off breeze, with a 2ft swell from the SE but with a juicy 13-second period. By the afternoon, the swell bumps to 4ft but the period drops, though the energy is building. It’s good, but the real standout is Tuesday the 7th. The morning brings a solid 5ft swell from the SSE with a very long 16-second period, but the wind is a messy cross-shore, making it a bit of a handful. The energy is pumping, but it’s really for experienced surfers only as it hits 6ft in the afternoon with a cross-on wind. Wednesday the 8th stays big with 8ft, but the cross-shore wind takes the edge off the perfection.
Now, here’s the highlight you’ve been waiting for. Thursday the 9th is my pick of the week. The morning delivers 7ft of clean, long-period swell (14 secs) from the SSE, with a light cross-off breeze and pumping energy. It’s excellent for experienced surfers. The afternoon improves even further: 8ft from the S with a 16-second period, clean glassy offshores, and even more energy. This is the session to circle on your calendar. Friday the 10th holds similar size and direction but with a bit more cross-shore influence, so it’s a notch below.
Saturday the 11th continues the run with a morning of 8ft, 17-second groundswell from the S, clean light offshores, and massive energy. Excellent conditions for the confident crew. The swell slowly backs off through Sunday the 12th, still with clean offshore winds, down to 5ft.
After that, the swell fades quickly into the middle of the second week, with smaller, weaker energy and only fleeting surfable windows. The weekend of the 18th and 19th offers humble, short-period leftovers, but nothing to get excited about. A definite lull sets in from around the 14th through to the end of the forecast period.
Best on offer: Thursday the 9th and Saturday the 11th at Ohara. Big, clean, long-period groundswell with light offshores. Be warned, this is expert territory once the waves go overhead. Keep an eye on the tides.
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.
