The Lowdown
Grim times ahead, folks. The next week and a half is looking pretty flat and messy around here. We've got a real dry spell on our hands, with day after day of weak, wind-blown junk. You're looking at a solid stretch from Tuesday the 18th right through to the following weekend with nothing but small, choppy waves. Honestly, for the most part, it's not even worth paddling out. You'll be fighting wind and getting nothing for it.
The first real glimmer of hope doesn't show up until Monday the 24th. We finally see a proper pulse of energy, with a long-period groundswell filling in from the SSE. Tuesday the 25th is the standout of this run. Swell sizes jump up to 9.8ft, and while the period is a touch long at 15 seconds, which can make beach breaks close out, the morning wind is basically glassy. That's the one to circle. After that, it stays solid but the wind turns more onshore and the quality drops off. By the 29th and 30th, a strong breeze just ruins it all, mixing things up into a complete mess.
Then, the big finale. On Monday the 31st, we're looking at a massive pulse of energy. The morning shows 11.5ft and the afternoon is predicted to be an absolute monster at 16.4ft with a combined wave energy reading of 16067. That’s serious, heavy water. The wind is light and favorable, but this is only for the hardcore crew. This is well beyond beginner territory; it’s expert-only, and even then, you need to know exactly what you’re doing. This same size carries into Tuesday the 1st of September. It's a promising, but slightly less certain, long-range forecast.
So, there you have it. A long, flat wait for a couple of proper days. The Tuesday the 25th looks like the most user-friendly of the big swells, and then the extreme stuff at the very end of the month is for the chargers with big cojones.

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.
