The Lowdown

Alright, Rusty here. Let’s talk about what’s coming up for the next couple of weeks.

First off, we’ve got a bit of a slow start. The surf’s been pretty flat and weak, with the first few days offering nothing but small, messy, cross-shore slop that’s not worth paddling out for. Honestly, through the 21st and 22nd, you’re looking at weak swell (120) and (226) respectively, with a cross-chop that just ruins any chance of a clean face. The 23rd is no better, with more cross-onshore junk. It’s a real blank stretch.

But hang tight, because Monday the 24th of August is where it finally lights up. The morning session at Hebara is the standout of the entire forecast. We’re talking a solid 7 ft swell from the SSE, and the period is a very long 18 seconds – that’s proper groundswell energy. The wave energy is pumping at (2516), and with the wind going glassy, the conditions are going to be absolutely pristine. The water is sitting at 80°, which is bang on average for this time of year, so no wetsuit worries. This is a clean, powerful, long-period swell, and for a beach-and-reef setup like Hebara, that long period might mean the sets are a bit more lined up and make paddling out a bit easier between them. Keep in mind, at 7 ft, this is a serious step up – it’s for experienced surfers only. The afternoon sees the wind shift, bringing in a cross-onshore breeze that chops things up, so get your session in early.

Tuesday the 25th still has some size, with 8 ft swell from the S and SSE, but the cross-shore wind adds a bit of bump. It’s still ridable and has plenty of energy (2285), but it’s not as clean as Monday morning. The rest of the week tails off into smaller, wind-affected surf, with a lot of poor conditions and marginal windows through the 26th, 27th, and 28th. The wind really gets up on the 28th with a fresh breeze making it lumpy.

Now, there’s a promising little window on Sunday the 30th of August. The morning shows a 4 ft SSE swell with a 12-second period and a light offshore wind from the NNW. That’s clean, with a solid wave energy of (525). It’s not huge, but it’ll be fun and user-friendly for a wider range of surfers. The early session is your best bet.

Looking further ahead into the first week of September, the first couple of days are mostly marginal, with small SE swell and cross-onshore winds. The real story, and it’s a big one, is on Thursday the 3rd of September. The models are showing a massive, biblical-sized swell hitting Hebara. We’re talking 33 ft from the ESE with a very long 18-second period. The combined energy is an astronomical (98121). The wind is light and cross-shore, which sounds perfect, but the wave height is so extreme that the file is saying it’s too big for this break. This is not a paddle situation – this is a survival situation, or maybe one for the tow crew and the absolute experts only. The same goes for Friday the 4th, with 18 ft and 12 ft swells, all still way too big for a standard session. By Saturday the 5th, it drops back to a more manageable 5 ft to 7 ft, but the cross-onshore wind makes it a choppy, less appealing option.

So, to wrap it up: your absolute best bet is Monday morning the 24th of August. It’s the peak of the window. The Sunday morning the 30th is a solid, clean backup. The rest is either too small, too windy, or dangerously huge. Don’t sleep on that Monday.

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.
