The Lowdown
Alright, mates, Rusty here. Let's break down the Blokken forecast.
It’s a pretty grim outlook for the next two weeks, with a whole lot of nothing to start. The wait is the main story here, with almost no surf worth talking about until the final days.
The only real highlight, and I mean the only one, falls on Saturday, August 22nd. Through the morning we get a tiny bit of life with a 4ft swell rolling in from the southwest, with a 6-second period. The wind is light from the north, so even though it's cross-onshore, it’s just a slight breeze, keeping the surface reasonably clean. Combined swell energy is a weak (69). It's not much, but it’s the most size we see for a long time. The afternoon holds the same 4ft swell from the southwest, but the wind turns onshore from the west-northwest and picks up slightly.
If we jump ahead to Tuesday, August 25th, we finally get a pulse of energy. Tuesday afternoon brings a 5ft northwest swell, with the combined energy jumping to a moderate (124). That’s the biggest swell of the entire forecast, but the wind ruins it, howling from the southwest at 28 mph, making for a messy, choppy cross-shore. That's more of a kitesurfer’s day. The morning of the 25th is cleaner with cross-offshore winds from the south-southwest, but the swell is smaller at 4ft.
Wednesday the 26th is similar, with a 4ft north-northwest swell but strong cross-onshore winds making it lumpy.
Everything before that is tiny. From the 11th right through the 21st, the swell rarely hits 3ft, and for days it’s 1ft or less. There are a few clean windows, like Wednesday morning the 12th with a light cross-offshore breeze, or Monday the 17th, but there is simply no swell to surf. The water temperature at Blokken is 71°F, which is much warmer than normal for this time of year, so at least it's comfortable while you wait.
So, the standout is Saturday, August 22nd for the best chance at a surfable wave in clean-ish conditions. Then the 25th and 26th offer real size but come with strong winds, so keep an eye on it if you're experienced and want some power. Otherwise, it’s a flat, windy stretch.
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.
