The Lowdown
Right then, let’s have a look at what’s on the cards for Blokken over the next couple of weeks.
To be straight with you, the first week and a half is a real write-off. From Friday September 11 right through to Wednesday September 23, the combination of swell and wind is just miserable. Swell is tiny, mostly around 0.7 ft to 4 ft, and the wind is nearly always onshore or cross-onshore, often a Moderate breeze or stronger. The wave energy is feeble, ranging from 10 to just 76 (combined energy). There’s nothing worth paddling out for, and honestly, it’s a proper frustrating stretch for anyone keen on surf. The water temperature is about average for the time of year, nothing unusual to report.
That big gap finally breaks on Wednesday September 23 afternoon—I know, feels like an age away. You get a sudden jump to 7 ft swell from the WSW, energy ramps up to 381, which is moderate to strong. Problem is, the wind is light cross-onshore, and it’s only rated as marginal. The period is short at 7 seconds, so not much push behind it, and it’s a bit of a messy one. But it’s the first sign of life.
Then, here’s the standout: Thursday September 24 morning. This is the one to circle on the calendar. Blokken sees 6 ft swell from the WNW with a 6-second period, combined energy of 213 (moderate), and the wind is glassy. That’s right, glassy conditions from the ENE at just 3 mph. For a spot that’s inconsistent and gets crowded sometimes, this is a rare treat. The waves should be clean and rideable for intermediate surfers—though 6 ft starts to get a bit much for beginners. Swell direction is NW, which isn’t bang on the optimum NNW, but with that glass, it’ll be well worth it. The rest of that day and into Friday September 25 morning, the wind stays light offshore (cross-off) too, with a 3 ft NNW groundswell, long 10-second period, and 198 energy. The longer period means better-shaped waves, but at a beach setup it can break a bit straight—still, with clean conditions, it’ll be fun.
The weekend of September 26-27 looks like it’s getting blown out again with cross-onshore winds and onshore gusts. So that Thursday morning window is your best bet by a long shot. The far end of the forecast (around Wednesday September 23 afternoon to Thursday September 25 morning) holds the only real promise, but remember, it’s a way off, so keep an eye on the updates.
Stay stoked.

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.
