Alright, grab your board and listen up. Rusty here, and I’ve been staring at the charts for your local stretch. It’s gonna be a bit of a mixed bag, but I’ll walk you through it.
The 16-day window kicks off, but honestly, we’ve got a rough start. The first couple of days are a write-off – you’re looking at pretty weak, messy conditions. The water temp is sitting at about 76°, which is pretty much bang on average for this time of year, so no surprises there.
We’ve got a long, quiet gap from the start until the end of the first week. The real action doesn’t even start to whisper until the 22nd of July. So, be patient.
The standout session, and the only one I’d really get excited about, is Wednesday morning, the 22nd of July at Ohara. The swell is going to be a solid 7ft from the east, with a period of 11 seconds. That’s a proper groundswell, packing a strong punch with a combined energy of 1228. The wind is dead calm, glassy, and the conditions are clean. This is for experienced surfers only – that size is no joke for a beginner, but for the crew who knows what they’re doing, it’s going to be an incredible session. The afternoon follows up with an 8ft swell from the NE and a light offshore wind, but that size is pushing expert territory, too.
Before that, the 18th and 19th of July see a pulse of swell, but the wind is either cross-onshore or onshore, making it choppy and poor. Not worth the paddle out.
After the 22nd, the swell drops back down, but we get some decent, clean conditions from the 23rd to the 24th of July. The 23rd afternoon has a 4ft swell from the ENE with a light cross-offshore breeze, and the 24th has a 3ft swell from the SSE with a clean offshore wind. Both are small and fun, but nothing to write home about compared to the 22nd.
The last few days of the month (from the 25th) look like a mixed bag of onshore winds and smaller, choppy swell. A few more clean slates here and there, but nothing that’s gonna get the heart pumping.
So, the takeaway is simple: if you’re an expert, clear your calendar for the morning of the 22nd of July. That’s the one. The rest of the time? It’s mostly small and clean for the learner crew, or blown out and messy.
Stay salty,
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.
