Table - best surf conditions forecast for Ohara over the next 16 days.
Right then, let’s have a look at what’s on the cards for Ohara over the next couple of weeks.
Honestly, the opening few days are looking pretty special. We’ve got a solid, long-period groundswell rolling in from the SSE, and those winds are staying offshore or cross-off. The water’s a bit colder than normal for this time of year, sitting at 73°, which is something to keep in mind. The wave energy is very strong, reading 1626 (moderate to strong), so you’ll feel that power.
Thursday morning (9th July) kicks things off with 6ft of swell from the SSE, a 14-second period, and cross-off winds. It’s a setup for experienced surfers only. The swell hangs around 5ft to 7ft through to Sunday, with periods stretching from 13 to 17 seconds. That’s proper groundswell, and with those offshore winds, the waves will be clean and lined up. The best of this run looks like Friday (10th July) morning: 7ft from the S, 15-second period, and offshore winds. That’s a standout. Saturday morning (11th July) is also a cracker, with 7ft from the S, a 17-second period, and gentle offshore winds. The energy is massive, hitting 2926 (very strong). This is expert territory, but for those who can handle it, the waves will be long and powerful. The break is inconsistent, so expect some wait between sets, but when they come, they’ll be worth it.
Now, from Sunday afternoon (12th July) into next week, the swell drops away. We go from 6ft on Sunday down to 2ft by Tuesday morning (14th July). The winds stay mostly offshore, but the wave energy plummets to around 186 (weak). The surf becomes very ordinary for a few days, with the period dropping to 8-11 seconds. It’s a real lull. There’s not much to get excited about from Monday (13th July) through to about Thursday (16th July). The wave heights are under 3ft, and the energy is low.
But then, things look like they’re building again. By Saturday (18th July) afternoon, we see a bump to 4ft from the SSE with a 12-second period, and the energy climbs to 571 (moderate). The winds are cross-off, so it should be clean. The real return to form looks like Sunday (19th July) through Monday (20th July). Sunday afternoon brings 6ft from the SSE, 12-second period, and clean conditions with a moderate energy of 1126. Monday morning (20th July) is a standout for the second week: 7ft from the SSE, 12-second period, and glassy winds. The afternoon pushes to 7ft from the SSE, 14-second period, with gentle offshore winds. The energy sits at 1831 (strong). That’s a solid, clean swell for experienced surfers. The inconsistency at Ohara means you’ll need patience, but the quality will be there.
After that, the swell tapers off again from Tuesday (21st July) onwards, dropping back under 5ft and into the ordinary range by the end of the week. The break is inconsistent, so these blank stretches are fairly normal for the area.

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.
