The Lowdown

Alright folks, Rusty here. Let’s be straight with you—this 16-day stretch for Blokken is a tough one. We’ve got a long, dry run of poor surf conditions ahead, with no real standout sessions to get excited about. The water is sitting at 69°F, which is a solid 5°F warmer than usual for this time of year—that’s notably warm, so you won’t need a thick wetsuit, but it’s the only thing that’s working in our favour right now.

The forecast kicks off Monday, August 31st, with a messy 7ft WSW swell at a short 7 seconds, but strong cross-shore winds are making it a washout. That pattern holds through the end of August and into the first week of September. Wednesday, September 2nd, sees the swell drop to ankle-snapping 2ft to 3ft with periods of just 4 seconds and weak wave energy (26 to 28), so it’s flat and choppy. The wind stays onshore or cross-shore almost every day, with moderate to strong breezes.

Thursday, September 3rd, bumps up to 5ft to 5ft from the WSW, but again it’s short-period (6 seconds) and lumpy from cross-shore winds. The wave energy is moderate (138 to 189), but the quality is poor. By Saturday, September 5th, the swell hits 7ft from the NW with a 7-second period and strong onshore wind—that’s big and ugly, only for the brave or the kited-out, and honestly, it looks more like a kite-surfing setup than paddle surfing.

We finally get a small window of hope on Sunday, September 6th, in the morning. The swell is just 3ft from the NNW at 8 seconds, with light cross-offshore winds from the SSW. That’s clean, with wave energy of 86, and it’s the only time in the entire forecast that the comment reads “surfable waves but very ordinary conditions.” It’s not pumping, but it’s the best we’ve got. The afternoon sees the wind swing cross-on, and it’s back to poor.

After that, from Monday, September 7th, right through to Tuesday, September 15th, it’s a long stretch of tiny, weak, or wind-blown slop. Swell heights rarely top 4ft, periods are mostly short (5-7 seconds), and wave energy is low (15 to 161). The winds are consistently onshore or cross-shore, with a few days of fresh to strong breezes. There’s a brief uptick on Friday, September 11th, with 4ft from the NNW at 7 seconds and moderate onshore wind, but the surf is still rated poor. By Sunday, September 13th, the swell drops to 2ft with a longer 9-second period, but cross-shore wind kills it.

The bottom line: Blokken is in a real slump. The only thing worth paddling out for is the early hours of Sunday, September 6th, when it’s clean and just about rideable. Otherwise, it’s a waiting game. The good news? These stretches don’t last forever—forecasts can change, and the next decent swell might be just around the corner.

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.
