The Lowdown
Right then, let's have a look at what we've got cookin' for Blokken. I'll be straight with you, it's been a lean stretch, and we're looking at a long, dry spell before anything worth paddling out for shows up. The forecast is pretty bleak for a while.
The whole 16-day window starts off with a real bummer. For days on end, from the start right through to late in the month, it's flat or nearly flat, and when there is a little bump, the wind is just ruining it. You're looking at nearly two weeks of poor surf conditions. The first real sign of life doesn't appear until Friday the 28th of August, and even then, it's just the beginning.
Now, the water temp is a talking point. When we finally get some swell, the ocean's sitting at a warm 71°, which is 6° warmer than normal for this time of year. That's seriously unusual, a proper warm blanket.
Friday the 28th of August afternoon is where it finally gets interesting. We've got a clean, cross-offshore breeze with a light breeze, and a new swell is showing up. It's a 6ft swell from the southwest, with a period of 6 seconds. The combined energy is a solid 254 (moderate wave energy) – the first real pulse we've seen. The conditions are looking "clean," which is a huge relief. It's the standout of the whole outlook. Be aware though, this is a short-period swell, so it won't have the same grunt as a groundswell.
Saturday the 29th of August, the swell actually gets bigger, up to 8ft from the southwest, and the energy rockets up to 716 (strong to very strong wave energy). That's a lot of power. But here's the catch – a fresh breeze swings onshore and it's gonna be lumpy and cross-onshore. It'll be a mess. For experts only, and even then, it's not gonna be pretty. That 8ft is too big for beginners, and the wind will chop it up.
So, the one true window is that Friday afternoon on the 28th of August. It's your best bet, but it's a long way off, and long-range calls are always less certain. For the rest of the time, it's a write-off. The setup doesn't look good for our normal surfing, but with all that wind and lumpy water on Saturday the 29th, if you've got a kite, that might be your thing.

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.
