The Lowdown
Alright, this is Rusty, and I’m looking at our only real option for the next couple of weeks: Ohara. Let’s get into it.
The water temp here is sitting at 80°, which is pretty much spot-on average for this time of year – nothing weird going on there.
We’ve got a bit of a wait for anything decent. The first few days are a write-off. Friday the 14th has a pulse of easterly swell pushing 6ft, but the wind is cross-off and the energy is strong (1326), yet the conditions are really only for experienced surfers. It’s a start, but it's not a standout for everyone. After that, Saturday through to next Wednesday looks pretty grim with onshore winds and choppy conditions – a proper lull.
The real standout window kicks off on Monday the 24th. We get a new long-period groundswell from the southeast, 6ft at 16 seconds. The energy jumps up strong (1902), but the wind is cross-shore, keeping things a bit lumpy. Still, that period is very long, and at a spot like this it can be a bit too straight for a beach break, so don’t expect perfect peaky barrels.
But the absolute best on offer hits on Wednesday the 26th morning. Ohara will be glassy – dead calm wind – with a clean 7ft swell from the ESE at 14 seconds. The energy is very strong (1841). That is a serious session, but let’s be real: 7ft is getting up there, and this is for experienced surfers only. The afternoon keeps it clean with an offshore wind and 8ft. This is the highlight, no question.
Thursday the 27th afternoon also looks good with clean cross-off winds and 6ft of east swell. A bit more manageable, but still solid. Crowds at Ohara can show up sometimes, so for that Wednesday glass-off, get there early.
After that, the surf fades through the end of the month. Friday the 28th still has some clean 5ft waves, but it’s dropping off.
Overall, if you’re an experienced surfer, lock in the 26th and 27th. If you’re a beginner, this whole stretch is mostly too big or too messy for you.
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.
