The Lowdown
Right then, let’s get into it. I’ve been staring at the charts for Flamand, and I gotta be straight with you – it’s a tough run ahead. The whole 16-day window is pretty grim, no real standouts to get excited about. The surf is almost always marked as "poor," and the wind is a constant problem. We’ve got a long gap here where it’s just not worth paddling out for the first week and a half, all the way from the start to around the 16th of August.
Now, let’s talk about what little action there is. The biggest spike in energy happens on the 16th of August. We’re looking at a solid 13 ft swell combo from the east, with a period of 12 seconds – that’s a proper groundswell. The combined energy is pumping at 4066 (that’s strong to very strong energy), but the catch is a screaming 28 mph cross-shore wind with thunderstorms. It’s a mess. For the experts who can handle a beating, there might be some big, raw, and unruly waves, but it’s not for the faint-hearted. By the afternoon, the wind drops a notch to 22 mph and turns cross-offshore, cleaning it up a bit, but it’s still a 10 ft swell. The score is barely a 1 out of 10. This is a serious, powerful wave for experienced surfers only, and even then, it’s a gamble.
Honestly, the most consistent you’ll get is the wind. It’s mainly cross or cross-off from the east and southeast, sitting between 12 and 22 mph nearly every day. The water temperature is sitting around 84°F, which is about average for this time of year, so at least you won’t be cold while you’re sitting there getting blown around.
Forget about the first week. The 17th and 18th of August offer a drop in size to about 7 ft to 5 ft, with the cross-off wind, but the direction is straight from the east, which is the worst for Flamand. It just doesn’t line up. The energy drops back into moderate territory (702 down to 308), and it’s still just not clicking.
The best-looking conditions, if you can call it that, are on the 24th of August. The Monday morning shows a 5 ft east swell, a 6-second period, and only 215 in combined energy. The wind is cross-off from the ESE at 19 mph. It’s clean, but the swell is weak and that short period means it’s going to be a bit dumpy and weak. Not a standout, just a slight chance to get wet if you’re desperate.
So, to wrap it up: the only window that even flirts with being interesting is the weekend of the 16th to the 17th of August for big-wave hunters, but the rest is a write-off. The winds are too strong, the swell direction is wrong, and the consistency just isn't there. It’s one of those stretches where the forecast is what it is. For now, I’d say hang up the board for a few days. Things can change, but right now, it’s a hard no.

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.
