The Lowdown
Alright, Rusty here. Let's get into it. The reliable south swell window is a bit of a slow burner for Ohara, but once it kicks in towards the end of the month, there's some serious stuff on the table. The water's sitting at a typical 78°F for this time of year, nothing unusual there.
The opening stretch this week is a bit of a tease. Sunday morning the 19th, we've got a clean 4ft ESE swell with a gentle offshore breeze, and the energy is moderate (302). It's surfable, but the spot is inconsistent, so don't expect a wave every set. The afternoon goes ordinary with stronger wind, so take the morning session. Monday and Tuesday offer small, clean waves around 3ft to 4ft, but the real kicker is Wednesday morning the 22nd. It's a tiny 3ft east swell, but with glassy conditions and that light offshore feel, you'll be scratching for a clean little runner. The energy is weak (168), but sometimes that's all you need for a fun slide.
The real standout action starts on Monday the 28th. The afternoon brings a solid 5ft south swell at 14 seconds, with moderate offshore wind. The energy jumps to strong (1219), and it's calling for excellent conditions for experienced surfers. This is the one to circle. Tuesday the 29th gets even bigger – 8ft to 7ft south swell, long period groundswell, and clean offshore winds. The energy is very strong (2367), but the size is pushing into expert-only territory. Wednesday the 30th is a monster: a 10ft south swell with a 16-second period, but the finder says it's too big for this break. The energy is extreme (5053). If you're a charger, the afternoon of the 30th with a 8ft SSE swell is a better bet.
The first week of August keeps the fire burning. Saturday the 1st afternoon has a clean 6ft east swell with offshore wind, but the real beauty is Sunday the 2nd. Both morning and afternoon offer a 4ft to 5ft SE swell with a very long 16 to 17-second period, clean and light winds. The energy is still very strong (1551-1705). This is a top pick for the whole window – the long period means it'll be better at the point or reef setup than a beach break, so keep that in mind.
The final standouts are Monday the 3rd. An 8ft SE swell with an 18-second period, but the wind is messy and cross-onshore in the afternoon, making it better for seasoned paddlers only in the morning if the light cross-shore holds.
For the best of the best: Sunday the 28th afternoon and Sunday the 2nd August are the true standouts. The 28th has the perfect combo of decent size, great wind, and strong energy. The 2nd August has the quality of a very long period groundswell with clean conditions. Crowds are possible at Ohara, so get in early.
Until next time, keep your eyes on the horizon.

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.
