The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on the cards for the Hebara region.
The water temperature is sitting at a very normal 80°F, right on the money for this time of year – no surprises there.
The first few days are a write-off. Thursday the 20th through to Saturday the 22nd, the swell is tiny and weak, mostly around 1 ft from the SE with period around 10-11 seconds, and the energy is pitiful (89-314). The wind is all over the place, mostly cross or cross-onshore, so the surface is messy. Honestly, not worth getting wet.
Sunday the 23rd brings a small improvement. The morning sees a little 2 ft swell from the east with a period of 9 seconds (174 energy), and the wind turns light and cross-offshore, so it’s clean. It’s surfable, but still very ordinary. The afternoon has a bigger pulse of 3 ft from the SSE with a long 14-second period, but the wind goes cross-onshore and the energy jumps to 508. Still marginal.
Monday the 24th is where things get interesting, but also tricky. The morning shows a 8 ft SSE swell with a very long 16-second period and massive energy (3148). The wind is light cross-onshore, so it’s a bit bumpy. This is big and powerful for Hebara – too big for beginners, and even experienced surfers will need to be on their game. The afternoon swells to 8 ft with even more energy (3665), but the wind picks up to a moderate cross-onshore, making it choppy. It’s a heavy, powerful groundswell, and the long period means it’s going to hit the beach breaks hard and fast – best saved for reefs or points, but here it’s a beach and reef setup, so expect some heavy, shifting peaks.
From Tuesday the 25th through Thursday the 27th, the swell goes absolutely nuts. We’re talking 12 ft to 16 ft SSE swells, periods of 11-16 seconds, and energy readings in the thousands (4434-7016). The wind is mostly cross or cross-on, and the condition reports say the swell is just too big for this break. This is expert-only territory, and honestly, even for the pros, it might be a washing machine. The setup looks more interesting for kite surfing than paddle surfing at this point.
Friday the 28th sees the swell drop back to 8 ft, but the wind is strong (15-19 mph) from the SSW and SW, creating a lumpy cross-chop. Energy is still high (2410-1140), but it’s messy and marginal.
Saturday the 29th is a bit better. The swell drops to 5-6 ft from the SSE with a short 8-second period, but the wind turns offshore from the NNE and N, so the surface cleans right up. The energy is lower (566-536), but the clean conditions make it a decent option for a more relaxed session.
Sunday the 30th is a standout. The morning delivers a 7 ft SSE swell with a nice 12-second period and clean offshore winds from the NNE (1066 energy). This is the best on offer in the whole forecast – solid, clean, and punchy. It’s not for beginners, but for experienced surfers, it’s excellent. The afternoon drops off a bit with a 6 ft swell and light cross-onshore wind, so get out early.
Monday the 31st is marginal, with a 5-5 ft swell and cross/cross-onshore winds. Not great.
Tuesday the 1st of September is promising. The morning has a 4 ft swell from the south with a 12-second period, and it’s glassy – the wind is light from the SE, almost nothing. The energy is moderate (621). This is a very good, clean session for a more intermediate surfer.
From Wednesday the 2nd onward, it’s a long run of poor conditions. The wind howls from the NE and NNE at 19-47 mph, dropping the quality to zero. The swell is small (3-6 ft) and inconsistent, with only a few clean moments from the offshore wind, but the energy is low and the wind is just too strong. Avoid.
So, the standout is Sunday the 30th morning – 7 ft SSE groundswell, clean offshore winds, solid energy. That’s the one to circle. The 1st of September morning is also a good, glassy session for those who want a quieter, cleaner wave.
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.
