The Lowdown
Alright folks, Rusty here. Gotta be straight with you—this stretch coming up is a tough one. We’re looking at a long, dry spell with no real surf on offer until the very end of the 16-day window. The guidance points to just one spot, Blokken, and it’s an inconsistent one that rarely breaks, so we’re in for a wait.
Right now, there’s nothing to get excited about. The forecast shows a gap of nearly two weeks with no worthwhile surf. A few tiny pulses of swell come and go, but they’re all rated as poor surf conditions. The wind is mostly onshore or cross-onshore, keeping things choppy and messy. The water temp at Blokken is sitting at 71°, which is a massive 7° warmer than usual for this time of year—very unusual stuff, feels like bathwater out there.
The first real hint of something happens on Tuesday, August 19th. Wednesday morning the 20th, we finally see some size. The swell bumps up to 6 ft from the W, with a moderate energy of 191, and the period is only 6 seconds—short-period windswell, not the most solid. Still, the wind is a gentle cross-onshore from the N, so it’ll be a bit lumpy. It’s the best we’ve seen in a while, but it’s still not a standout.
The real standout—and I mean the only one worth circling on your calendar—is Wednesday afternoon, August 20th. The swell hits 8 ft from the NW, with a period of 8 seconds and a combined energy of 694, which is a solid moderate to strong energy. That’s proper size. But here’s the catch: at 8 ft, this is expert-only territory, and with a short period, it’s going to be a bit crumbly and fast. The wind is a moderate cross-onshore from the N, so it won’t be glassy, but it’s rideable if you’ve got the skills. The swell direction is from the NW, and Blokken’s optimum is from the NNW, so it’s close but not perfect. The crowds are listed as “sometimes,” so you might have a few others out there, but it won’t be a zoo.
After that, the swell drops off fast. The run-up to this is basically two weeks of flat, choppy junk. It’s a tough forecast for an inconsistent spot like Blokken—it tends not to stay poor for long, but this blank run is a bit more normal for the area. Hang tight, and keep an eye on the forecasts for changes.
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.
