The Lowdown
Alright, Rusty here, let’s talk about what’s coming up at Hebara.
Honestly, folks, it’s a pretty grim start. We’ve got a solid run of poor surf conditions stretching from Sunday the 16th right through to the end of the following week. The wind is a constant problem, mostly cross-onshore or cross-shore, and the swell is small and weak. The combined energy is low, hovering around 145 to 299 for most of that time, which is just anemic. The water temperature is sitting at 80°, which is bang on average for this time of year, so at least you won’t be cold while you’re staring at the chop.
There’s a bit of a tease on Monday the 24th of August. The swell jumps up to 7 ft to 7 ft from the SSE with a very long period of 16 seconds, and the combined energy shoots up to 2071, which is moderate. But the wind is still cross-shore, making it lumpy. It’s a real shame, because that long period groundswell would normally be great for a setup like this, but the wind is just going to mess it up. The forecasts are a bit more solid for that week, so it’s a case of “could have been a good one.”
The real standout, and the one that’s got me a little excited, is Sunday the 30th of August. We’re looking at a solid 13 ft swell from the SE with a period of 13 seconds. The combined energy is a massive 5396, which is strong. But here’s the catch – that size is well over 8 ft, so this is strictly for experts only. Too big for beginners, and even for the average surfer. The wind is a clean cross-offshore from the NNE with a moderate breeze, which is a major positive. The forecast says it’s favorable, but the swell is just too big for this break. It’s going to be a wild, heavy, and powerful day. The same goes for Monday the 31st, with the same size and conditions. So, if you’re an expert with the right equipment, that Sunday the 30th is your window, but it’s a long way out, so keep an eye on it.
Before that, on Tuesday the 25th, the swell is still around 7 ft to 8 ft from the SSE, but the wind is a light cross-shore in the morning, which might make it a little more manageable for strong intermediates, but the score is low. The rest of that week is just a write-off with strong onshore winds.
So, bottom line: the first week and a half is a total washout. The second week has some size, but the wind is a constant issue until the very end. The 30th and 31st are the only true standouts, but they are not for the faint of heart. If you’re not an expert, you might as well save the petrol.
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.
