The Lowdown
Alright, Rusty here again, looking at the same stretch of water but in feet and miles per hour.
It’s a slow start, no doubt about it. The first few days are small and nothing to write home about.
Sunday the 19th is where things start to turn. The morning has some clouds, but the wind is light and cross-offshore, keeping the waves clean. The swell is a modest 4ft from the ESE, with a period of 9 seconds, and the combined wave energy is moderate at 227. It’s not big, but it’s clean. The afternoon gets even better with a gentle offshore breeze and a 4ft ESE swell. The water temperature is about normal for this time of year.
Monday the 20th is also a solid day. A light offshore wind in the morning with 3ft of E swell, and the afternoon picks up a bit more breeze, but it’s still offshore, with the same size swell. Good, clean, small waves.
The real standout is Monday the 27th. This is a week and a half out, so don’t book the trip yet, but it looks excellent. The morning is a bit choppy, but the afternoon is magic. A light ESE breeze, cross-offshore, and a solid 7ft swell from the SSE. That’s a long-period groundswell at 14 seconds, which means power and shape. The combined wave energy is a massive 1985. This is for the experienced crew only – way too big for beginners. If you’re comfortable in big surf, this is the one.
Now, watch out for Tuesday the 28th and Wednesday the 29th. The swell is predicted to be over 13ft and the energy readings are through the roof – but the spot is just too big to handle. It’s a monster, and unless you’re tow-in only, stay on the beach.
Things settle down after that. Thursday the 30th has a clean 7ft SW swell, and Friday the 31st offers a nice 5ft ENE swell with a moderate offshore wind. Both are solid options for the experienced surfer.
So, the best of the bunch is Monday the 27th afternoon at Ohara. Big, clean, and powerful. The second best is Sunday the 19th afternoon for a smaller, more mellow session.
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.
