The Lowdown
Alright, Rusty here with the surf for Ohara in feet and miles.
The water is running about 82°F, so a touch warmer than usual. First few days are a no-go. Saturday the 29th has a tiny 2ft east swell, 12 seconds, cross-shore wind, energy at 175. Poor. Sunday and Monday the 30th-31st are flat with less than 2ft waves and cross-winds. Nothing doing.
Tuesday the 2nd of September we get a glassy morning: 3ft from the ESE, 10 seconds, dead calm, energy 220. That’s clean and fun for a log. Wednesday afternoon gets better: 4ft from the ESE, 7-second period, but offshore wind at 9 mph and clean. That’s a real nice window.
Thursday the 3rd: morning has 2ft from the east, 12 seconds, cross-off wind at 12 mph, energy 440. Afternoon shows 4ft from the SSE, 7 seconds, offshore at 16 mph, energy 345—clean, lined up. That’s the best of early week.
Friday and Saturday the 4th-5th are blown out with heavy rain and onshore winds. Swell gets to 7ft but it’s messy, energy 657. Skip it.
Sunday the 6th: 8ft to 8ft from the ENE, cross-shore, energy over 1000. Too big and choppy for most.
Monday the 7th is a standout: 8ft from the east, 9 seconds, light cross-off from the southwest, energy 1586. Excellent for experienced surfers. Afternoon: 6ft from the south, 12 seconds, offshore wind, energy 1980. That’s the one to circle.
Tuesday the 8th is massive: 13ft from the SSE, 12 seconds, energy 4914. Expert-only, probably overhead for the break. Clean but huge.
From Wednesday the 9th onward, onshore winds and rain ruin the run. Swells stay big (10ft to 12ft) but choppy. Thursday and Friday the 10th-11th drop to about 4ft to 5ft, mostly cross-on, marginal. Saturday the 12th has clean offshore at 16-19 mph with 5ft to 5ft from the ESE—rideable but not great.
Sunday the 13th goes huge again: 12ft to 13ft from the SSE, 13-14 seconds, energy over 4000. Way too big.
Best bets: Wednesday afternoon September 2nd for clean small waves, and Monday September 7th for powerful, clean swell for the experienced crew.
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.
