The Lowdown
Let me give you the straight rundown for Flamand over the next couple of weeks. Honestly, it’s a rough stretch coming up. The swell window is pretty much shut for a while, and even when there’s a little bump in size, the wind and conditions are working against us. If you’re hanging for a wave, you’re gonna need some patience.
Right off the bat, from Tuesday the 15th through the rest of this week and well into the next, we’ve got nothing but poor surf conditions on the cards. The combined swell energy is weak, mostly sitting between 58 and a bit over 200, with short, choppy periods around 5 to 8 seconds. It’s blown-out, cross-shore rubbish for the most part. The water temp is about average for this time of year, so no surprises there, but it won’t matter much because you won’t be paddling out for any good waves.
Things stay pretty flat and messy through the weekend and into the beginning of the following week. There’s a noticeable gap of several days where there’s just no real surf to recommend. Around the 22nd, you’ll see a slight bump to maybe 2 ft, but it’s still weak and cross-shore. The energy stays low.
Now, if you’re really keen and looking that far ahead, the only flicker of real hope comes late in the window. On Saturday the 26th, we finally see a jump in swell—up to about 4 ft from the NNE, with a cleaner period of 10 seconds. The combined energy jumps to 525, so there’s finally some decent power behind it. The wind looks cross-offshore from the ESE, which means clean faces, and the break is fairly exposed to this NNE direction. The crowd situation at Flamand is “sometimes” busy, so you might have some company, but it won’t be a zoo. That Saturday afternoon window is the standout of the whole 16 days, but it’s only a marginal call due to possible tide issues. By Sunday the 27th, the swell holds around 4-4 ft, but the wind goes more cross-shore, so the quality drops off a bit. For a beginner spot like this, anything over 5 ft gets a bit much, but 4 ft is still manageable. The period around 10 seconds is solid—long enough for some push, but not so long that it breaks too straight for this setup.
Honestly, if you’ve got the patience, hold out for that Saturday the 26th afternoon session. It’s the only time in this whole forecast where conditions line up for a half-decent paddle.

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.
