The Lowdown
Alright, grab your wettie, let's talk about the stretch ahead for Hebara. It’s a mixed bag, with a rough start and some serious muscle later on, but there are a couple of windows where it could turn on.
Right now, the surf is pretty much a no-go. We’ve got small, weak energy running for the first few days—the swell’s tiny, under 3 feet, and the wind’s not doing us any favors. The water is sitting at 80.2°, which is right on the money for this time of year, nothing weird there. You’re looking at poor conditions through the 23rd, with the energy staying weak (93-173). It’s a frustrating start, and we’ve got a solid six-day gap of nothing to get excited about.
The first real sign of life shows up on the 24th. Monday morning has the combo of a 1.6ft easterly swell and a long 12-second period, with the wind going totally glassy. The energy bumps up to a moderate 179. It’s surfable, but it's still pretty ordinary—not worth skipping work for, but at least the board gets wet.
Then things get interesting. The swell really fills in from the 25th through the 28th, but it comes with a side of mess. The energy jumps into the strong range, hitting 1715 on Tuesday the 25th and peaking at a huge 5589 on Thursday the 27th. We're talking solid 8ft to 13ft of south swell, but the cross-shore and cross-onshore winds are going to chop it up. This is big, unruly surf—more for the experts or the kite crew. The standout for this period is Thursday the 28th. The morning has the swell at a hefty 13ft, but the wind is lighter and more favorable. The comment says it’s too big for this break, and it is, but if you’re a charger and the tide lines up, that's the one window where it might be semi-rideable. Friday the 29th sees the swell back down to 7ft, but with a storm risk, it's not ideal.
After that, things back off. The 30th and 31st see the swell drop, but the winds turn blustery again, keeping the quality down. Then the first week of September gets wild. The 1st is completely out of control—16ft of southerly swell with a 10560 energy reading and fresh winds. That’s a washing machine. The 2nd and 3rd stay poor with strong cross-shore winds and messy conditions. There is a small window on the 3rd with a 15-second period groundswell, but it's not enough to save the day with that wind.
So, bottom line: the first week is a right-off. The 28th is the one standout, but it’s a beast. Keep an eye on Monday the 24th as your best bet for a clean, yet small, paddle. Everything else is either small and weak or big and sloppy. Stay patient.

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.
