The Lowdown
Alright folks, Rusty here with the outlook for the region.
First up, the water temps are about average for this time of year, sitting around 80°F on Saturday morning.
Right now we’re looking at a pretty quiet run of surf through the first week. From Saturday, August 15th through to the end of that week, there’s not much to get excited about. The swell is small, mostly around 3ft to 5ft, coming out of the ESE and E with short periods of 7-10 seconds. The wind is persistently cross-onshore, making for choppy, poor conditions across the board. There’s a gap of several days with no real recommendations, just marginal or poor surf.
It’s not until Monday, August 24th that things start to change. We see a big pulse of swell arriving, with heights jumping to 8ft from the SE with a period of 17 seconds. The trouble is, by Tuesday, August 25th through Thursday, August 27th, the swell gets too big for this spot. We’re looking at 12ft to 15ft from the SSE with periods of 14-15 seconds. The wind is mostly cross-shore, which isn’t ideal, but the main issue is the size. This is only going to be suitable for experts, and even then, at a beach-and-reef setup like Hebara, it’s going to be heavy and tricky. The long period swell (over 15 seconds) will have it breaking straight at the beach, so keep that in mind.
The standout moment actually comes later, on Saturday morning, August 29th. The swell drops to a more manageable 4ft from the ESE with a period of 13 seconds. But the real winner is the wind – a light 6 mph cross-offshore breeze will keep the surf clean and lined up. Expect very good surf conditions for that morning session. It’s a brief window of quality before the wind swings around in the afternoon.
So, if you’re after the best on offer, your one true standout is Saturday morning, August 29th. That’s the window to clear your schedule for.
Stay safe out there.

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.
