The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a bit of a slow start on the horizon, so don’t be in a rush to grab your board just yet. The first real action is a week away, so we’ll have to be patient.
The first decent look comes on the morning of Wednesday, July 23rd. Ohara is showing a small 3 ft swell from the east with a 10-second period. The real kicker here is the wind: glassy, mate. That’s a major positive. The sea will be clean as a whistle. The combined energy of the swells is weak (147), so it’s not going to be a powerhouse, but with those conditions, it’ll be a fun little session for an intermediate. After that, the swell drops off into tiny, weak stuff for several days, and the wind patterns get messy cross-on. Thursday the 24th through to the weekend are a write-off – mostly poor surf with very ordinary conditions. You’re looking at a gap of about four days with nothing worth paddling out for.
Now, hold onto your hats, because things get interesting in the second week. The real standout is Monday morning, August 3rd. Ohara picks up a solid 5 ft swell from the south with a 13-second period, pushing a strong combined energy of 1273. The wind is a light cross-off from the west at 10 km/h, which will keep the waves clean. This is groundswell, so expect better shaped waves with more energy. It’s a bit big for beginners, but for experienced surfers, this is excellent. The water temperature is sitting at 78°F, which is about average for the time of year, so no surprises there.
The next best option is Tuesday afternoon, August 4th. The swell shifts to the east-southeast, still a solid 5 ft with a very long 15-second period. The wind is a clean cross-off breeze, and the combined energy is strong (1578). This is another one for the experienced crew, as the long period might make it a bit stiff at the beach break, but the quality will be there.
Finally, the morning of Wednesday, August 5th, is a gem. You’ve got 5 ft from the east-southeast, a 14-second period, and the wind is completely glassy at 0 km/h. The combined energy is strong (1117). This is as good as it gets for clean, powerful surf. Crowds are possible at Ohara, so get in early.
So, to wrap it up: the first week is a slow burn with one quiet but clean morning on the 23rd. The second week, specifically the 3rd, 4th, and 5th of August, is where the magic is. The Monday morning (3rd) and Wednesday morning (5th) are the true standouts. Get those dates in your diary.

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.
