The Lowdown
Right, folks, Rusty here. Let's have a look at what we've got for Blokken over the next couple of weeks. First thing you need to know: the water is way warmer than usual for this time of year, sitting at 69 °F, which is a massive jump from the norm. A real treat.
Honestly, the opening stretch is a tough watch. For the first ten days or so, it's mostly poor surf conditions. There's a lot of wind from the west and southwest messing things up, and the swell periods are short, around 5 to 7 seconds, making for weak, gutless waves. The combined energy is often low, and it's mostly choppy or lumpy. It's a real struggle.
The first sniff of something decent doesn't come until Saturday, the 12th of September. The morning sees a pulse of 6 ft swell from the northwest with a 7-second period, but what makes it special is the light south wind sneaking offshore. The combined energy is solid, and the wave comment finally suggests "clean" conditions.
But the real standout, the absolute best on offer, is Saturday afternoon, the 12th of September. The swell drops a touch to 6 ft from the northwest, but the period lengthens to 8 seconds, and we get glassy conditions with a light sea breeze from the east-southeast. The combined energy is still pumping (373). The report says "expect good surf conditions" – and you bet I'm excited. This will be clean, lined-up, and the best session of the whole forecast. Get on it.
After that high, the following days fade with smaller, weaker swell and winds turning onshore again. It’s a classic case of a narrow window lighting up, then fading out.
Stay stoked,
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.
