The Lowdown
Alright, Rusty here again. Let’s talk about Hebara. First week’s pretty flat and messy, but there’s a huge pulse of swell coming in the second week.
The forecast from Thursday the 13th onward is rough. Wind is cross-onshore or side-shore almost every day, shredding the weak swell. Wave heights mostly around 6 ft to 5 ft early on, but it’s choppy, not worth it. Swell energy stays moderate (between 100 and 600) until it drops to weak (below 200) around the 18th. There’s a glassy moment on Friday the 21st morning, but only 2 ft from the ENE with a period under 8 seconds – that’s ankle-biters, not surf.
Then, bam. Sunday the 23rd of August morning rolls in with 6 ft from the SE, a very long 15-second period, and light cross-offshore wind. That’s clean, powerful, and the combined energy jumps to 2121 – strong stuff. That’s the standout for experienced surfers. It keeps building: Monday the 24th brings 10 ft from the SSE with a 16-second period, and Tuesday the 25th morning goes glassy with 12 ft from the SSE and energy at 5398. That’s heavy, proper groundswell.
Thing is, at over 8 ft, and period over 15 seconds, Hebara’s beach-and-reef setup is going to close out hard and be for experts only. By Wednesday the 26th, we’re looking at 12 ft to 13 ft, then Thursday the 27th morning hits a monstrous 33 ft from the south with energy at 49228 – that’s well past the break’s limit. That setup looks way more interesting for kite surfing than paddle surfing.
Friday the 28th morning settles to 6 ft from the south with a short 8-second period and light cross-shore wind – more manageable but still lumpy.
So, for the experienced crew, the morning of Sunday the 23rd of August is your best call – clean, big, and powerful. For anyone else, that first week is a dud, and the second week is too big for this spot. Stay smart out there.
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.
