The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Ohara over the next couple of weeks.

It’s a pretty quiet start, so don’t rush out the door just yet. The first real window of decent surf kicks off on Sunday morning, the 19th of July. We’ve got a clean 4 ft swell coming from the ESE with a period of 9 seconds, and the wind is offshore from the south. That’s the best on offer for the opening stretch. The combined energy is moderate at 288, and it’s surfable, but don’t expect perfection. Water temperature is sitting at 78°, which is about average for this time of year.

The next nod goes to Tuesday morning, the 21st of July. Swell holds around 4 ft from the east, period bumps up to 10 seconds, and the wind is cross-off from the SSW. Moderate energy again at 290. It’s clean, but the afternoon winds pick up and ruin it, so make it a morning mission.

The following Saturday morning, the 25th of July, there’s a small window. A 3 ft east-northeast swell with a short 8-second period, but the wind is light offshore from the south, keeping it clean. Energy is moderate at 215. Worth a look if you’re desperate.

Now here’s where it gets interesting. Sunday the 26th of July, in the afternoon, we get a tiny 2 ft swell from the southeast, but the period rockets up to 14 seconds. That’s a long-period groundswell, and combined with light offshore wind, it’ll be glassy. Energy is moderate at 232. For a point break or reef, that could be a gem, but at Ohara it might be a bit straight. Still, it’s clean.

Then we hit the big stuff. Monday the 27th of July, the morning sees a 4 ft swell from the SSE with a 15-second period, but the wind is cross-on from the northeast. The energy is strong at 1063. The afternoon is more promising: 7 ft from the SSE, 14-second period, cross-off wind, and very strong energy at 1919. This is getting serious.

Tuesday the 28th of July morning: 10 ft from the SSE, 14-second period, cross-off wind, and very strong energy at 3228. This is too big for most, definitely experts only. The afternoon is even bigger: 12 ft from the south, 17-second period, cross-off wind, and energy at 6592. Massive.

Wednesday the 29th of July is the standout for size, but it’s a warning. Morning sees 23 ft from the south, 17-second period, cross-off wind, and extreme energy at 46702. That’s a beast. The afternoon is 18 ft from the south, offshore wind, still enormous at 11254. This is not for paddling; this is for tow-in or just watching. Honestly, the setup is more interesting for kite surfing than paddle surfing at this point.

Thursday the 30th of July drops down to 8 ft from the south in the morning, 10-second period, offshore wind, strong energy at 1403. Still big, but cleaner. Afternoon holds at 8 ft from the south, same wind, energy at 1050.

Friday the 31st of July is the real highlight. Morning: 8 ft from the SSW, 8-second period, moderate offshore wind, energy at 751. The afternoon is similar: 7 ft from the SSW, 8-second period, energy at 704. Both are rated as very good surf conditions. That’s the pick of the period for confident, clean, surfable waves.

Saturday the 1st of August keeps going: morning 6 ft from the south, 8-second period, offshore wind, energy at 542. Afternoon 6 ft, same direction, energy at 487. Good, clean waves.

Sunday the 2nd of August fades out. Morning: 2 ft from the east, 16-second period, offshore wind, moderate energy at 323. Afternoon: 2 ft, same direction, light offshore, energy at 261. Clean but small.

So, the best on offer is the Friday the 31st of July through Saturday the 1st of August. Solid 8 ft to 6 ft swell from the south, clean offshore wind, and moderate energy that’s actually surfable. The big stuff mid-week is only for the brave or the insane.

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.
