The Lowdown
Alright, grab a brew and let's chew the fat about what's going on at Blokken. I'll level with you, this is a rough patch. We're looking at a 16-day run, and the first week is a write-off. From the 4th right through to the 11th of September, there isn't a single session worth getting wet for. Strong winds, onshore junk and the wave quality is just poor. You'd be wasting your time. The combined swell energy gets up there, hitting 423 on the 9th, but it's coupled with a near-gale cross-onshore that makes it a total mess.
Let's find the silver linings. The first real chance at something half decent is the morning of Saturday the 12th of September. There's some light rain, but the wind swings offshore from the ENE at a mere 3 mph. That's clean! The swell is a small 4ft from the NW, with a short period of 6 seconds, so no real power—combined energy is a weak 109. It's surfable, but very ordinary. Still, for a quick fix with clean conditions, it's the only show in town for that first week.
The real standout doesn't come until the very end of the forecast. On the morning of Saturday the 19th of September, things start to look good. Clear skies, a light offshore breeze from the East at 15 mph, and a 5ft NW swell with a 7-second period. The combined swell energy hits a moderate 289. The conditions will be clean, and it's the best quality wave we've seen in the whole outlook. If you can be patient, that Saturday morning is the one to target. The water at Blokken is sitting at 69°F, which is much warmer than normal for this time of year, so leave the thick suit at home.
Also, the morning of Friday the 18th is worth a nod. It's glassy with a 5ft WNW swell, but the period is short at 5 seconds. It's surfable but still ordinary. For the rest of the month, there are a few mornings with small, clean waves, but nothing special. The big story here is a whole lot of wind and not much quality. Honestly, for a stretch like this, the setup at Blokken looks far more interesting for a kite surfer than a paddle surfer on those windy days.

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.
