The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
To be straight with you, the next 16 days are a tough watch. We’ve got a long stretch of flat or blown-out conditions before anything worth paddling out for shows up. The first real window of clean surf doesn’t arrive until the 6th of September, so prepare for a solid week and a half of staring at a lake.
From the 23rd of August right through to the 5th of September, it’s a write-off at Blokken. Swell is tiny, wind is all over the place, mostly cross-on or strong cross-shore, and the energy readings are pathetic—mostly two-digit numbers, with weak energy (91) on the 23rd, dropping to single digits from the 26th onwards. The 29th of August afternoon sees a spike in swell to 7ft from the WSW, but with a strong breeze cross-shore and a combined energy of 407 (moderate energy), it’s a messy, choppy mess. Not for paddling. That setup looks more interesting for kite surfing than paddle surfing.
On the 1st of September morning, there’s a brief moment with offshore wind from the NW and a 4ft swell from the NNW, period 7 seconds, but the energy is weak (102) and the break is inconsistent here, so I wouldn’t get your hopes up. The 3rd of September has a similar onshore vibe.
Finally, we get a glimmer of hope on the 6th of September. Sunday morning sees a gentle offshore breeze from the SE and a tiny 2ft swell from the WSW, period a short 3 seconds. The energy is a paltry 7 (weak energy). But the afternoon cleans up properly: offshore wind from the ESE at 12 mph, 2ft swell from the WSW, period 4 seconds, and the combined energy is just 17 (weak). It’s clean, but the swell is small and short-period. It’s the best on offer. For a pure, clean session on a small board, that Sunday afternoon is the standout. The water is about average for the time of year. For the rest of the 7th, it’s back to cross-shore junk.
So, bottom line: wait until the 6th of September for a clean but small window. The rest of the month is a write-off.
Rusty.

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