The Lowdown
Alright, Rusty here. Let’s break down what’s happening.
The next couple of weeks are pretty quiet for Blokken. The first surfable window doesn’t show up until the 30th of August. From the 21st through the 29th, it’s all poor conditions – small, weak swell, and messy winds. The water is unusually warm at 71°F, with a 6°F anomaly, so it’s much warmer than normal for this time of year.
The one standout is Sunday the 30th of August. The afternoon brings a 6ft swell from the WSW, with a period of 7 seconds and combined energy of 321 (moderate). The wind is light and cross-offshore, giving you clean, rideable waves. It’s the best of the bunch, but it’s still a marginal call. Crowds can be a factor at Blokken, so expect some company.
After that, it’s back to small, messy surf. The 31st and early September see strong winds and lumpy conditions, and by the 5th of September there’s a tiny clean swell from the north, but it’s only 2ft – not worth the effort.
Bottom line: if you’re going to paddle out, make it the 30th of August afternoon. Otherwise, keep the board in the car.

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.
