The Lowdown
Right then, let’s have a look at what’s on offer for Blokken over the next sixteen days. To be straight with you, it’s pretty grim. This stretch of coast is going to be mostly flat or choppy, and even when there’s a bit of bump, the quality just isn’t there. The water is sitting at 71°F, which is much warmer than normal for this time of year – over 5°F above average, so that’s a real standout, but it won’t help the waves.
The first surfable moment – and I stress *moment* – shows up on Tuesday the 18th of August in the morning. We’ve got a tiny 4ft swell from the west, period of just 5 seconds, meaning weak, short-period windswell. The combined energy is a very low 72, so there’s hardly any push. The only reason I’m mentioning it is because the wind goes glassy. It’s the calmest we’ll see, but the waves are so weak they’re barely surfable for a beginner. It’s not worth a paddle out.
After that, things stay messy. The wind is mostly cross or onshore, and the wave heights bobble between 2ft and 5ft but with poor conditions. There’s a bit of a pulse trying to build around Friday the 21st of August, when we see 7ft from the NNW in the morning – that’s a moderate energy of 715 – but it’s accompanied by a fresh onshore wind and rain showers. That’s a full-on windswell, not clean, and honestly, it looks more interesting for a kite surfer than anyone paddling a shortboard. The period is only 8 seconds, so it’s not groundswell.
Later in the month, on Monday the 25th of August, we get a 6ft NNW swell with moderate energy of 269, but again, the wind is cross-onshore and it’s lumpy. No standouts here. The forecast keeps showing poor surf conditions right through, with scores rarely reaching a 1.
There are long gaps of nothing. From the beginning of this period right through to the 18th, it’s pretty much a write-off, and after that, it’s only marginal. The consistency at Blokken is inconsistent, and this run of poor forecasts reflects that. It’s a bleak outlook. Things don’t look like they’ll turn around.
Keep an eye on the charts, but for now, I’d leave the board in the car.

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.
