The Lowdown
Alright, let's get into it. The next couple of weeks are looking pretty bleak for surf, to be honest. The first week is a total dud. From now through the end of August, the wind is all cross or cross-off, and the waves are there but they’re ugly. You’ll see some chest-to-head-high stuff around the 28th and 29th, with 5ft to 6ft swell from the east, but it’s coming in with a short period of just 7 to 8 seconds and the energy is moderate, around (321 to 462). But the wind has it chopped up and messy. Not worth the drive.
Now, there’s a tiny glimmer of hope right at the end of the month. On Monday the 31st of August and into Tuesday the 1st of September, things start to look a bit better. We get a proper groundswell on Monday morning, 6ft from the east with a nice long 12-second period. The energy jumps way up to (888), which is strong. The wind goes light and cross, and it’s clean. That’s the best looking window in the whole forecast. But it’s still a marginal call with questionable tide, so don’t get too excited.
By Tuesday the 1st, the swell drops to 4ft from the east, period drops to 10 seconds, but the wind goes light cross-off and it’s clean again. Wave energy is moderate (354). It’s a bit smaller, but much cleaner than anything we’ve seen.
The only spot on the menu is Flamand. It’s a beginner wave, inconsistent, and it can get crowded sometimes. It’s fairly exposed to the swell, and it likes the swell from NNE, but we’re getting it mostly from the east and northeast through this period, so it’s not the perfect angle. Still, when it lines up, it’s a fun little wave.
After that little burst, from Wednesday the 2nd of September onward, it’s back to poor surf with cross winds and weak, short-period junk. The energy drops back to (200-400 range), and the period goes short again. A couple of days in the second week show marginal conditions, but nothing worth getting excited about.
So, the standout is clear: the morning of Monday the 31st of August into Tuesday the 1st of September. If you’ve got a flexible schedule, that’s your window. It’s not perfect, but it’s the best we’ve got by a long shot.

Information about the Flamand Surf forecast
The above surf forecast table for Flamand provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flamand can be found by selecting the local surf guide option on the grey menu. Our Flamand 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 (Flamand) 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 Flamand 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.
