The Lowdown
Hey everyone, Rusty here. Let's be straight—this outlook for Hebara is a bit of a patience game. The first week and a half is pretty much a write-off for any decent waves, with messy winds and weak, choppy conditions. The real story here kicks off in the second week with a powerful pulse of swell, but you'll have to wait for it. Hold onto your boards.
The first real chance we see is on Friday, August 23rd. Through the morning, it's still a bit dicey with a cross-onshore wind and a building 6ft SSE swell, but things get interesting in the afternoon. The wind drops right off to glassy, and we're looking at a clean 6ft swell from the SE with a very long 14-second period. The combined wave energy is strong (1822). This is the first time the stars start to align, and for experienced surfers, this afternoon session is the standout for the entire run. It's going to be clean, powerful, and have proper groundswell lines.
Then comes Saturday, August 24th. The morning is the absolute best on offer. It's glassy again with a solid 8ft SE groundswell at a very long 15-second period. The wave energy is cranking hard (3288). This is proper, powerful surf. But a heads up: 8ft with that much juice is for experienced folks only. The afternoon gets a bit lumpier with a SSW breeze, but the morning is the one to circle on your calendar.
After that peak, it gets big but messy. Sunday, August 25th, we see a massive 13ft SE swell, but the wave energy is colossal (7558). However, that west-southwest wind will put some chop on it. Honestly, at that size with lumpy conditions, this break might be more interesting for the kite crew than a paddle session. By Monday and Tuesday, the swell drops quickly but the wind stays strong, leaving us with average, choppy surf to round out the forecast period.
In short: forget the first week and a half. The gold is the afternoon of Friday the 23rd and especially the morning of Saturday the 24th, with clean, glassy conditions and powerful groundswell.
Stay patient, and I'll see you 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.
