The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

First up, we've got a bit of a slow start. The first real chance to get wet comes in on Friday, the 7th of August, at Ohara. The water is sitting at 78°, which is a touch colder than usual for this time of year, so you might want a thin spring suit. The swell is coming from the south at 5 ft, with a solid 12-second period behind it, packing a serious punch of energy (1029). The wind is offshore from the SSE, which will keep things clean. The catch is that Ohara is inconsistent, so don't expect a wave every minute. Still, the conditions are excellent for experienced surfers – this is a standout if you've got the skills.

Saturday morning, the 8th, drops a little to 4 ft from the south, still a clean 11-second period, and the wind is a light cross-offshore. The energy is still decent (622), but it's not as powerful as Friday. The afternoon sees the swell shift to the ESE at 4 ft, period up to 13 seconds, but the wind turns cross-off again. It's cleaner, but the energy is climbing (952).

Sunday the 9th brings a bump in size to 6 ft from the ESE, with a 13-second period. The wind is a light cross-onshore in the morning, and by the afternoon it's a cross-shore breeze. The energy is high (1131 and 1165), but the wind is just enough to put a little texture on the face. Not the best of the run.

Monday the 10th is a write-off. Strong cross-onshore winds, up to 22 mph, and the swell is blown out. The energy is huge (1673), but it's messy. Leave it.

Tuesday the 11th sees the wind swing offshore again, with a cross-off from the WSW and SSW. Swell is 6 ft to 6 ft from the east, 12-second period, and the energy is pumping (1014 to 1911). The conditions are clean, so it's a good session for the more experienced crew.

Wednesday the 12th has a tricky morning. The swell is 7 ft from the ESE, but the period is a short, weak 6 seconds (431 energy). That's not going to offer much. The afternoon, however, is a gem. The swell drops to 3 ft from the east, 10-second period, and the wind goes glassy. It's a perfect little window for a longboard or a funboard.

From Thursday the 13th through to Saturday the 15th, the winds are onshore and strong, with the swell hanging around 5 ft to 8 ft. The energy is high (over 1000), but the wind is ruining it. The afternoon of the 14th has an 8 ft, 12-second east swell, with a cross-shore wind, but it's still a bit of a mess. This is more of a kite-surfing setup than a paddle session.

Sunday the 16th is still windy and lumpy, but the energy is dropping.

Now, here's the next real standout. Monday the 17th of August, the wind goes offshore from the south. The morning has a clean 5 ft east swell, and the afternoon bumps to 5 ft from the ENE. The energy is solid (864), and the wind is a moderate offshore breeze. This is going to be clean, lined up, and the best of the second week. It's a proper session for anyone.

Tuesday the 18th through to Saturday the 22nd sees a consistent run of smaller, clean surf. Swells between 3 ft and 4 ft, mostly from the east and south, with periods around 8 to 10 seconds. The winds are light, often offshore or cross-off. The energy is low to moderate (around 275 to 333), so it's not going to be powerful, but it will be clean and fun. The morning of the 22nd has a 4 ft south swell, light cross-off wind, and is a nice way to end the outlook.

So, to sum it up: the best on offer is Friday the 7th of August for the experienced surfer, and Monday the 17th of August for a cleaner, more accessible session. The rest of the time, pick the glassy windows and the light offshore days.

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.
