The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Ohara.
Right off the bat, we’ve got some serious juice on Monday the 7th, but it comes with a big catch. The swell is a solid 10ft from the south, with a combined energy of 1647, so that’s strong stuff. The water temp is sitting at 82°, which is a touch warmer than normal for this time of year. The wind is a strong offshore breeze, which would normally have me drooling, but this swell is too big for this break. It’s a session for the experts only if they’re feeling brave, and the risk of thunderstorms makes it a tricky call. The afternoon cleans up a bit with a fresh offshore, but still, that size is pushing it.
Tuesday the 8th sees the swell drop to 7ft from the SSE, with moderate energy (678). The wind goes cross-offshore, which is okay, but the forecast calls it a marginal day. The crowd factor is a "sometimes" here, so you might have company, but the waves aren’t screaming quality.
The rest of the week into the weekend is a bit of a write-off. Wednesday the 9th has some size (8-8ft) but fresh cross-off winds and low scores mean it’s not worth chasing. From Thursday the 10th through to Sunday the 13th morning, it’s a real drought. Swell drops to knee-high, wind is onshore or cross-onshore, and the energy is weak (under 400). There’s a gap of about four days where you’re better off doing something else.
Now, things start to look up a little on Sunday the 13th afternoon. A tiny 2ft east swell with a light cross-off wind and clean conditions. The energy is low (239), but it’s surfable. Monday the 14th morning brings a 4ft SE swell, glassy with a slight offshore breeze, and the energy jumps to 395. That’s the best of a pretty average run. The crowd is a "sometimes" at Ohara, so you might get a few waves to yourself if you’re early.
The second week offers a few flickers. Tuesday the 15th afternoon has a clean 4ft SE swell with a light offshore, but it’s inconsistent because of the break’s nature. Wednesday the 16th morning is clean with a 2ft easterly, and Thursday the 17th morning has a 3ft ESE swell – nothing special, but rideable. The standout in this later period is Monday the 21st and Tuesday the 22nd, when a massive, very long-period groundswell rolls in (18-19 secs, energy up to 9014). That’s real deep ocean energy, 13ft from the ESE, but the wind is a fresh cross-onshore, ruining the party. The period is so long it’ll be hard to handle at a beach break, but it’s something to watch. For a point break or reef, it would be epic, but here it’s a messy, powerful beast.
Overall, the best bet is Monday the 14th morning – clean, manageable size, and a bit of that warm water. If you’re a glutton for punishment, the 21st and 22nd have the size, but the wind is a killer.
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.
