The Lowdown
Alright folks, Rusty here. Let's talk about what we've got on the cards for the next couple of weeks.
First up, the honest truth: we're in for a pretty flat and messy week. From today, Thursday the 20th of August, right through to the 23rd, there's really nothing worth paddling out for. The waves are tiny, the wind is a pest, and it’s all a bit of a chop-fest. You’d be better off cleaning the wax off your deck or having a beer. That’s a solid four or five days of no-go.
Now, hold onto your boardies, because Monday the 24th of August is where it gets interesting. The early morning session at Hebara is looking like the standout of the whole forecast. We’ve got a solid groundswell, 7 ft from the SSE, and with a period of 18 seconds that’s a whole lot of power and energy coming through (combined energy of 3024). But the real magic is the wind – it’s glassy. Dead flat, clean water. That’s going to be firing. Keep in mind though, at 7 ft and that long period, this is not a beginner wave; it'll be barrelling and powerful, so it’s one for the experienced crew. For the experts, this is the session to mark.
Later that same Monday afternoon, the wind swings around to a cross-onshore and churns it all up again. Then Tuesday the 25th brings a bit more size but with iffy winds again, so it’s messy and tough. The water temp at Hebara is sitting at 80°F, which is pretty much exactly what you’d expect for this time of year, so the wetsuit can stay at home.
The rest of that week and into the next is a bit of a mixed bag. There’s plenty of swell – some days pushing 8 ft or even 10 ft – but the wind is mostly onshore or cross-shore and strong. By the 27th and 28th, we’ve got big numbers (12 ft) but with a strong breeze and a lot of rain and storm risk. Honestly, that setup looks more interesting for the kite surfers than us paddle guys. It’s just messy, blown-out, and poor quality.
Into the first few days of September, the swell drops off a bit, but it’s still windy and cross-onshore. There are a few mornings where the wind is lighter, like Wednesday the 2nd, with a light breeze, but even then the conditions are only marginal. Nothing that screams "go-time".
So, to wrap it up: the one big highlight is that glassy Monday morning (24th Aug) at Hebara. If you’re an experienced surfer, don't miss it. The rest of the 16 days is a write-off – either no swell, or swell with bad wind. It’s one of those runs where you take the one good window and make it count.
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.
