The Lowdown

Alright, let’s get into it.

The next couple of weeks are a real mixed bag, a tale of two extremes with a long flat stretch in the middle. We’ve got some clean, rideable windows early on, then a pulse of serious, stormy energy moves in, but it’s wrapped up in messy winds for the most part. The real standout is a solid, clean window that’s just too big for the spot, a real tease. Hang tight.

Our first real look is Ohara, and to be honest, it’s a slow burner. The water is sitting at 81° which is about normal for this time of year, so no surprises there.

Monday the 14th is where things start to get interesting. The morning brings in a clean 3ft of southeast swell with a 9-second period, and we’ve got light offshore winds. The energy is moderate at 200. It’s small, but with the wind off, it’ll be clean and workable. Afternoon picks up a touch, to 3ft, still with the offshore wind, and energy climbing to 285. This is your best bet for a proper surf this week.

Tuesday the 15th is a bit of a wild card. The morning has a push of 3ft easterly swell, but the wind is howling offshore at 15 mph, and the energy is strong at 831. It’s got some push, but it’s probably lumpy. The afternoon, however, is a beauty. The wind drops to glassy, the swell backs off slightly to 2ft, and the energy settles to 401. That’s a clean, fun session on offer if the rain showers stay away.

The next morning, Wednesday the 16th, has more of that glassy goodness with 2ft east swell and the energy at 297. It’s worth a paddle before the wind swings around onshore and the quality drops off for a few days.

Now, that gap. From Wednesday afternoon through to the following week, it’s pretty grim. The winds turn cross-onshore and choppy, and the swell is all over the place. It’s not until a week later, on Monday the 21st, that things get interesting again, but it’s a problem of plenty. We see a massive 15ft south swell with a 10-second period and offshore winds, but the forecast flags it as too big for this break. The energy is a massive 4430, but this is one for experts only, and possibly not even then at this spot.

The standout window is the morning of Sunday the 20th. We’ve got 10ft of SSE groundswell at 13 seconds, the wind is glassy, and the energy is a hefty 3777. The call is that the swell is predicted to be too big for the break, and honestly, with that kind of size and that long a period, it’s going to be relentless. For the average surfer, it’s a no-go. For a select few, it might be the wave of the season.

The following Tuesday the 22nd sees the swell dropping fast, down to 8ft, but the wind is onshore and it’s getting messy again. After that, it’s back to small, poor conditions and a real battle against the chop. There’s a small window on Thursday the 24th with clean 4ft east swell and offshore winds, but the period drops to 7 seconds, which is short, and the energy is weak.

Further out, the last Saturday the 26th shows a promising 10ft SSE swell with a 14-second period and offshore winds, but again, it’s flagged as too big. That’s another one for the experts only.

In short, for the next 16 days, your best clean waves are on the 14th and the morning of the 16th. Everything with real size is either blown out or just too big for this setup. The crowd situation at Ohara is only “sometimes”, but with the conditions that are on offer, there won’t be many out.

Keep an eye on that Sunday the 20th, though. If the size comes down even a little, it could be something special.

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.
