The Lowdown
Right, let’s have a look at what’s on offer at Ohara. The water temperature is sitting at 82°, which is a touch warmer than usual for this time of year, so you might not need that wetsuit.
First things first, the next few days are a write-off. We’ve got light rain and persistent cross-onshore winds, with the swell barely pushing 2ft and a combined energy around 142 (moderate). The quality is just poor, nothing to get excited about at all. This rough patch stretches through until the end of the month.
Then, on Tuesday, September 1st, the swell nudges up to 3ft from the ESE, but the wind is still cross-on and the energy is moderate (324). Still not worth paddling out for.
The first real glimmer comes on Wednesday, September 2nd. The morning session is glassy, with clear skies and a light ESE breeze. The swell is 3ft from the ESE, period 10 seconds, and the combined energy is 203 (moderate). Conditions are good, and the waves are clean. This is the first proper chance to get wet, but it’s not a standout. The afternoon stays clean with a gentle offshore breeze from the south.
Thursday, September 3rd, looks clean in the morning with a cross-offshore breeze, but the swell is still only 2ft from the E. The afternoon shows a bit more size at 4ft from the SSE, but the period drops to a short 6 seconds, and the wind is strong. The quality is marginal.
From Friday, September 4th, right through to Sunday, September 6th, the conditions are back to being poor. Cross-onshore winds and lumpy, choppy surf. The swell is there, but the wind is a nightmare. The energy climbs to very strong levels on the 6th (1127 to 1278), but the wind is cross-shore and messy.
Now, here’s the big one. On Monday, September 7th, the swell jumps to 10ft in the morning and 12ft in the afternoon from the E, with a period of 9-10 seconds. The combined energy is massive – 2688 to 4250. The wind is a clean cross-offshore. But here’s the catch: the swell is predicted to be too big for this break. This is expert-only territory, and even then, it’s risky. The waves are going to be powerful and heavy. For a seasoned charger, this is the best on offer, but it’s not for everyone.
Tuesday, September 8th, still has a big swell at 8ft from the E, but the wind is onshore in the morning and cross-shore in the afternoon. The conditions are marginal.
The rest of the forecast period gets hammered by strong winds. From Wednesday, September 9th, through to Sunday, September 14th, the wind is relentless – fresh to strong breezes, mostly cross-onshore, with heavy rain and thunderstorms. The swell is often there, but the quality is poor. A few days, like the 13th and 14th, have clean conditions with cross-offshore winds, but the swell is small and the period is short (6-7 seconds), so the energy is only moderate.
So, the standout is Monday, September 7th. If you’re an expert and you can handle some serious size, that’s the day. For everyone else, the best bet is the glassy morning on Wednesday, September 2nd.

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.
