The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks at Hebara are a real mixed bag, and you’ll need to pick your moments. The first week is pretty average, with onshore winds and only small, short-period swell. The real juice arrives in the second week, around the 24th and 25th, but with a big caveat about size.
Right now, Thursday the 13th has a bit of east swell at 5ft, but the cross-onshore wind is making it choppy and messy. Not worth the paddle. The water temp is 80°, which is about normal for this time of year, so no surprises there. Friday the 14th is a bit better in the morning with lighter cross-shore wind, offering some 5ft east swell, but it’s still pretty average. Saturday the 15th sees the swell build a touch to 6ft, but the wind picks up and it gets lumpy. Sunday the 16th is more of the same – 5ft to 6ft, but it’s all short-period (8-9 seconds) and cross-shore, so it won’t be breaking with any real power. The combined energy stays moderate for most of this, around 500 to 1000.
After that, the swell drops right off. From the 18th through to the 21st, we’re looking at small, weak waves – in the 2ft to 4ft range – and a lot of it’s onshore or closing out. There’s a brief blink of life on the morning of the 22nd with a clean 3ft NNW cross-offshore breeze, but it’s not enough to get excited about. The 23rd is windy and junky.
Now, hold onto your board for the 24th. Monday afternoon the wind drops to glassy, and a longer-period southeast swell (12 seconds) rolls in at around 4ft. Clean as a whistle and the start of something much better. The wave energy jumps up to 640, and it’s the good stuff.
Tuesday the 25th is where it’s at. The swell cranks up to 7ft to 8ft from the southeast with a solid 14-second period. This is a proper groundswell. The morning looks excellent with a clean, cross-offshore breeze – this is the standout. Expect some proper sets and a lot more power, but be aware this size is pushing it for beginners. The energy is up over 2000, which is strong. This is your day if you’re comfortable in waves well over head-high.
Wednesday the 26th still has great waves, 7ft to 8ft with a 12-13 second period, but the wind swings cross-off in the morning which is still good, but the afternoon gets onshore and messy. The morning could be epic too, but the 25th morning is the pick.
Now for the big warning. By the 27th, the swell explodes. We’re talking 13ft to 15ft from the southeast. That’s way too big for this spot, and it’s only for experts, if anyone. The energy readings are off the charts (over 6500). Even with good wind, this is not a paddle-surfing situation. By the 28th, the wind howls from the southwest and it’s just a big, lumpy mess. Forget it.
So, the call: Forget the first eight or nine days. You’re waiting for the morning of the 25th of August. That’s the standout – solid, clean, long-period groundswell. The morning of the 26th is also worth a look. Just be careful of the 27th – that’s way beyond the comfort zone for most of us.
Rusty out.

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.
