The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the coming weeks.

To be straight with you, the first ten days are a bit of a write-off. We’re looking at a long, quiet stretch with no real surf to speak of. From Friday the 24th right through to the end of July, the swell is tiny and the conditions are ordinary. You’ll see a few small, weak waves around 1ft to 2ft, but with light onshore or cross-shore winds and poor surf quality, it’s not worth paddling out for. The combined energy is weak, barely cracking triple digits at best (143) and often dropping below 100. The water temperature is about what you’d expect for this time of year, nothing unusual.

The first real glimmer of hope comes on Monday the 3rd of August. The swell starts to build, and by the afternoon at Ohara, we’ve got a 3ft ESE groundswell with a period of 9 seconds. The wind goes offshore, clean, and the combined energy jumps to 225 (moderate). It’s a solid step up, but the real standouts are just around the corner.

Tuesday the 4th of August is the one to circle. The morning brings a 4ft SE groundswell with a very long period of 16 seconds, and the wind is offshore – gentle and clean. The combined energy is a strong 1094. This is excellent surf for experienced surfers. The swell direction is matching the optimum for this spot, and you’ll be looking at clean, well-shaped waves. The period is long, so expect longer lulls between sets, but the energy is there. By the afternoon, the swell builds to 6ft (15 seconds) and the energy hits 1506. It’s getting bigger, so stay sharp if you’re not an expert.

Wednesday the 5th of August is the top of the heap. The morning delivers an 8ft SE groundswell at 16 seconds, with a light cross-offshore breeze. The combined energy is a very strong 3283. This is expert territory – too big for beginners – but for the crew who know what they’re doing, it’s prime. The swell direction is spot on. The afternoon sees the swell push to 10ft, and while the conditions are still clean, the forecast says it’s getting too big for this break. The morning session is the one to aim for.

After that, from Thursday the 6th, the swell balloons to 15ft and up, but with strong onshore winds and the size being way too big for Ohara, it’s a no-go for surfing. More of a kite-surfing spectacle if anything.

Bottom line: The first week-plus is a dud. The best of the entire 16-day window is the morning of Wednesday the 5th of August – that 8ft SE groundswell with light wind and huge energy is the standout. Tuesday the 4th is also a fantastic option, slightly smaller but still powerful.

Stay patient, and get ready for that big pulse.

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.
