The Lowdown
Alright, Rusty here again. Let’s look at the same stretch in the numbers you’d use on the water. The outlook for Blokken is a full 16 days of mostly poor surf, with a huge gap in the beginning.
For the first two weeks, from July 29th through August 12th, it’s a real struggle. Swell heights are tiny, from 0.7 ft up to about 3 ft, with short periods and awful wind. It’s a constant cross or cross-onshore, keeping the surface lumpy and choppy. The combined swell energy is weak, reading between 4 and 85 (moderate at best), and the water temperature on the 29th is 69°F, which is much warmer than the average for this time of year.
The only shot you get is August 13th, Thursday morning. We finally see a 3 ft west swell, with a 5-second period. The combined energy bumps up to 61 (moderate energy). The wind turns cross-off from the NNE at 16 mph, cleaning up the surface nicely. Blokken is an inconsistent wave, so it’s not a reliable spot, but this is the best it’s going to get. It’s a small window, and the crowds will be light.
So, in short: don’t bother for the first two weeks. The August 13th morning might be a small, clean window if you’re patient. The long blank run is just how it goes here sometimes. Keep your eyes on the sky.
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.
