The Lowdown

Alright mates, Rusty here. Let’s break down what Ohara’s got for us for the next couple of weeks.

First thing, the water’s at 81°, which is bang on the average for this time of year. Nothing to write home about.

We’re starting off slow. Saturday the 22nd brings a 3ft easterly swell with an 11-second period, and the energy is moderate (288). The wind is a cross-off from the SSW, so it’s clean, but this spot is inconsistent and the swell is just average. You might snag a wave, but don’t plan your day around it.

Sunday the 23rd is a total loss. Small, choppy, cross-on wind. Save your energy.

The real standout—the only one worth setting an alarm for—is Monday morning, the 24th of August. We’ve got a 3ft SSE groundswell with a very long period of 18 seconds, and the combined energy is a strong 1035. The wind is glassy, dead calm from the SSE. That means clean, lined-up waves with real push. But with that long period, the waves might be a bit too straight for the beachbreak, so find a good peak. This one’s for the experienced crew, not for the groms.

The rest of the week is a mixed bag. Monday afternoon and Tuesday (24th and 25th) see the swell picking up to 6ft – 6ft with strong energy (1647–1901), but the wind is cross-off and the quality is just marginal. It’s clean and surfable, but not top-tier.

Wednesday the 26th afternoon brings a fresh offshore wind from the SSW at 19 mph, which cleans things up, but the swell is dropping to 4ft and the energy is fading (615).

Thursday the 27th afternoon has a decent chance with a moderate offshore wind and a 4ft S swell, energy at 531. Could be a fun little session.

Then it gets ugly. From Friday the 28th onward, the wind turns onshore or cross-shore, and the swell stays small and messy. There are a couple of glassy moments (like Friday morning the 28th and Sunday the 30th), but the swell is tiny and the conditions are poor. You’ll be fighting chop and onshore junk.

By the time we hit September, the wind really cranks up. The 3rd and 4th of September have big swell—10ft—but it’s accompanied by fresh cross-onshore winds at 19–22 mph, making it a choppy, lumpy mess. That’s kite-surfing territory, not paddle surfing.

So here’s the takeaway: your one and only shot is Monday morning, the 24th of August. Glassy, long-period groundswell, clean lines. It won’t last, but it’s the only true standout in the whole 16-day window. After that, we’re looking at a 10-day stretch of mostly poor conditions. Forecasts can change, but right now it’s a one-hitter.

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.
