Alright surfers, Rusty here. Let’s chew the fat on what’s coming for Ohara over the next couple of weeks. To be straight up, this is a slow start with some proper firecrackers lighting up later on.

Right now, the water temp is sitting about average for the time of year, so the usual wetsuit is fine. But we’re looking at a pretty quiet opening. Saturday the 4th has some tiny 2ft E swell, but the wind is a cross-off, and with combined energy at a weak 84, it’s just not doing much. Surfable, but nothing to write home about. Sunday the 5th is even smaller, with poor conditions and energy dropping into the 60s. Monday the 6th sees a jump in size to 5ft-5ft but the wind goes cross and cross-chop makes a mess of it; that energy is moderate (374-422), but the quality is poor. That’s a write-off.

Tuesday the 7th is where things get interesting. The morning has 4ft from the SSE with a 15-second groundswell period and energy cracking at 1101. That’s some proper energy moving through. But it comes with a cross wind. It’s marginal, but you can feel a shift coming. By Wednesday the 8th, the swell builds to 8ft from the SE with a 16-second period – that’s a long-period groundswell, so it’ll have some punch. Energy is massive at 4535. Winds are light cross-on in the morning, but the afternoon cleans up slightly with a cross breeze and energy at 5535. This is expert territory, though; 8ft is only for the skilled.

Now, the standout window. Thursday the 9th afternoon hits with 8ft from the SSE, 16-second period, and a cross-off wind. Energy is 2865. That’s clean, powerful, and has excellent conditions for experienced surfers. But the real gem is Friday the 10th. Morning has 8ft S swell, 16-second period, and glassy conditions with no wind. Combined energy at 3233. Afternoon is nearly as good, with a gentle offshore wind from the S and energy at 3033. This is the pick of the run – clean, powerful, long-period groundswell. For a break like Ohara that can be inconsistent, seeing conditions this good is a treat. Keep in mind the long period might make it a bit straight at the beach, so watch your line.

Saturday the 11th still holds, with 7ft-7ft S swell and offshore winds, energy around 2000. Good stuff but dropping. Then it fades. Sunday the 12th is smaller with cross-on wind, and from Monday the 13th onward, it’s mostly poor, small surf with chop and cross-onshore winds, fading to 2ft swell by the 17th. The energy drops to double digits – weak. The blank run looks set for several days from the 13th to the 17th. There’s a little spike on the 18th afternoon with 7ft SSW swell, but short 7-second period and cross-off wind means it’s marginal and not worth getting excited about.

So, to keep it simple: the first week is quiet, but Friday the 10th is your day – glassy, big, long-period groundswell. Thursday the 9th afternoon is a close second. Everything else is either small, chopped, or for experts only.

Stay stoked and keep an eye on that Friday slot.

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.

Ohara is 2 km (1 miles) from Ohara. If you plan a holiday in Chiba, look for hotels and other accommodation in Ohara. Ohara has rooms for a wide range of budgets as well as car hire and transport links.
