The Lowdown
Righto, gather 'round. Rusty here, and I've got the lowdown for your local stretch. It's gonna be a bit of a mixed bag, so let's get into it.
First up, the good news? Well, it's mostly a waiting game. For a solid week from now, you're looking at a lot of wind-affected slop and onshore junk. The first real glimmer of hope doesn't pop up until Tuesday the 8th, and even then, it's not for the faint-hearted. The water's feeling pretty average for this time of year, nothing special to report on the temp front.
So, the standout of the whole 16-day window has to be Ohara on Tuesday the 8th. The morning's bringing a clean 8ft S swell, and the wind is swinging around to a light cross-offshore. The energy's solid (1379) and it's a proper SSE groundswell with a 10-second period, so those waves are going to have some push. It's set up for experienced surfers only at that size, but for those who can handle it, it's going to be proper. The afternoon cleans up even more with a moderate offshore wind from the SSW, with 7ft waves. Crowds are a "sometimes" thing there, so you might have a few mates out, but nothing insane.
Now, the rest of the outlook has a few other smaller windows. Friday the 11th is worth a paddle. The morning goes glassy as a mirror – dead calm – with a 4ft ENE swell. The period is short (7 seconds), so it'll be a bit fat and weak, but the surface will be perfect. The energy is low (255). The afternoon sees a clean offshore wind and a tiny 2ft E groundswell with a great 14-second period, but again, it's small. Saturday the 12th stays clean but tiny.
After that, things get a bit ordinary again through to the middle of the month. The morning of Wednesday the 16th is clean but marginal, with 3ft E swell and a cross-offshore wind. Then, on Thursday the 17th, we get another glassy morning with a 4ft E swell. It's rideable, but nothing to set the world on fire. The energy is weak (203). That's about it for the solid, clean options. The long-range stuff is all pretty wind-affected and small.
So, to break it down: mark your calendar for Tuesday the 8th if you're an experienced surfer and want the biggest, cleanest swell of the period. Otherwise, the glassy mornings on the 11th and 17th will be your best bet for a small, clean paddle.
Stay stoked, and don't let the flat spells get you down. 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.
