The Lowdown
Right, let’s have a look at the 16-day picture for Blokken.
Straight up, it’s a grim outlook for the next few weeks. We’ve got a long, dry stretch of barely any surf at all. The first few days are a write-off – tiny, weak and onshore. The water is running at 68°, which is much warmer than normal for this time of year; that’s a real standout, but it won't help the waves.
The only sniff of anything happens right at the very end. On the morning of September 28 (that’s a good two weeks away) we finally see a pulse of energy. The swell jumps to 5ft from the north, with a 7-second period. The combined energy hits 215 – that’s moderate, but it’s accompanied by a moderate cross-shore breeze. It won’t be clean, but for Blokken in this run, it’s the only game in town. It’s best suited to intermediate surfers; beginners will find the size a bit much, and the wind won’t be kind.
Before that, the whole stretch from now until practically the end of September is full of tiny, weak slop. There are days with winds that are offshore or cross-off, like Tuesday morning the 15th and Monday morning the 22nd, but the swell is barely a ripple. The period on some of those tiny days goes long – up to 10 to 12 seconds – but there’s no energy (values like 3 to 7). A long period on no swell just means you’re bobbing.
Honestly, this is one of those blank runs where the area just goes flat. Nothing to recommend for a surf. If you’re desperate for a paddle or a kite session, the stronger breeze on the 17th and 19th might be more interesting for kite surfing than paddle surfing.
Hang in there, but the forecast can always change. For now, it’s a waiting game.

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.
