The Lowdown

Alright, Rusty here. Let's talk about what's cookin' for the next couple of weeks around Blokken. I've got to be straight with you—this forecast is lookin' pretty grim for a long stretch. The good news is there might be one small window of hope way down the track, but you're gonna have to be patient.

Right now, we're in a tough spot. From Thursday the 10th right through to Thursday the 24th, it's a desert out there for decent waves. The whole setup is just wrong: messy winds, mostly onshore or cross-onshore, and tiny, weak swells with poor surf conditions. The water at Blokken is a balmy 68°, which is over 5° warmer than usual for this time of year—really notable, that warm water hanging around. But it doesn't help when the surf is flat and choppy. There's a few pulses of energy, like Sunday the 13th morning with a 4 ft swell from the west, but it's just blown out. Even when the swell ticks up a bit, like on Wednesday the 16th with a 4 ft swell and combined energy hitting 103, the onshore gale rips it to shreds.

Then on Thursday the 17th, we finally see some real energy with combined energy up to 192, and swell at 4 ft from the NNW—but again, it's cross-onshore and choppy. This is a beach break setup, and with strong winds and messy conditions, honestly, this looks more interesting for kite surfing than paddle surfing.

The one standout, and I mean the *only* one worth marking on your calendar, is Friday the 25th of September. It's a long way off, so take it with a grain of salt, but the early morning session at Blokken looks special. We've got a solid 7 ft swell rolling in from the west. That's big enough that beginners should sit it out—this one's for the experienced crew. What makes it magic is the glassy conditions, with the wind going dead calm (a slight air at 5 km/h from the SE). The water will be clean, no chop, no bumps. The combined energy is pumping at 492, so there's plenty of push. That's a proper groundswell with a 7-second period, so it'll be a bit more punchy than lined up, but with glassy conditions, you'll find some fun ones. The downside? The wind swings onshore by the afternoon and messes it up, and crowds are possible here, so get out early.

Apart from that Friday morning window, the whole 16-day run is a write-off. A blank run like this is pretty normal for the area when the wind patterns lock in unfavourable. Still, a window like that on the 25th is worth waiting for. So keep your eyes on the horizon, but for now, it's a waiting game.

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.
