The Lowdown
Hey, Rusty here again. Let’s break it down for Hebara in feet and miles per hour.
Water temp is around 81°F, pretty normal for this time of year. No surprises.
The real gem is Tuesday morning, 11 August. You’ve got chest-to-head high easterly swell at about 7ft, with a 10-second period, and a light offshore breeze from the north-northwest at 9 mph. It’s going to be clean, glassy, and packing moderate-to-strong energy (1115). This is for the experienced crew only – too big for beginners. The east swell lines up perfect for the break. Crowds are sometimes around, but it won’t be packed.
Tuesday afternoon, the wind shifts hard to the southwest at 22 mph, cross-shore, and it gets lumpy. Forget it.
Wednesday and Thursday are smaller – around 5ft to 6ft – but the wind is onshore or cross, with choppy conditions. Not worth it.
Friday morning, 14 August, offers a small window with a clean cross-offshore breeze at 12 mph and 5ft swell. It’s marginal, but you could grab a few fun ones.
Sunday morning, 16 August, is the other standout. Swell bumps up to 8ft from the east, 11-second period, with a clean cross-offshore north-northeast wind at 16 mph. Strong energy at 1332 – this is legit groundswell. Again, expert territory. The afternoon wind messes it up.
From Monday the 17th onward, the surf fades hard. Swell drops under 3ft for days, and the wind is mostly onshore or cross-onshore from the south. There’s a tiny chance on Thursday morning, 20 August, with a 5ft south-southwesterly swell and a light cross-offshore breeze – but the period is only 8 seconds, so it’s windswell. A few waves, but nothing special.
The last week of August sees some bigger groundswell return – up to 5ft from the southeast – but the wind stays onshore, keeping it choppy.
Bottom line: Tuesday morning, 11 August, and Sunday morning, 16 August. Those are your two windows. The rest is a long flat spell or too messy.
Rusty.

Information about the Hebara Surf forecast
The above surf forecast table for Hebara provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hebara can be found by selecting the local surf guide option on the grey menu. Our Hebara 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 (Hebara) 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 Hebara 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.
Hebara is 8 km (5 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.
