The Lowdown
G’day, Rusty here. I’ve been staring at the charts for Blokken and I’ve got to be straight with you—it’s a tough stretch ahead. The whole 16-day window is pretty much a write-off for decent surf. Basically, from now through the 22nd of August, there’s not a single good session on the cards. The swell is tiny, the wind is messy, and the energy is just not there. Let’s break it down.
We start off Friday the 7th of August with a bit of northwest swell at 3 ft, but it’s coming from the NNW with a short 8-second period and the combined energy is a weak 76. The wind is onshore, so it’s messy and poor. That’s the same story for the next few days—tiny waves, cross-shore or onshore winds, and hardly any push. The swell barely ticks over 2 ft for most of the first week, with periods staying under 8 seconds, so it’s windswell at best, and it’s blown out.
There’s a weak little spike on Monday morning the 10th of August—glassed off, 0.3 ft from the north with a 9-second period, but honestly, that’s not surfable. Then Monday afternoon gets a bit of a jump to 4 ft, but it’s a 4-second period and a 35 km/h cross-onshore. That’s just a lumpy mess, not worth paddling out for.
The middle of the second week, around Tuesday the 18th of August, we see the biggest swell of the whole period: 4 ft from the NNW with a 6-second period. The combined energy finally hits 131, which is moderate, but it’s onshore and the period is short. It’s gonna be a bumpy, choppy affair. Even the biggest stuff is only for the hardcore, and even then, it’s not great.
Honestly, the whole 16 days is a blank run for surf. The swell is too small, too short-period, and the wind is never lined up. For the first week, you’re looking at 0.7 ft to 3 ft with onshore or cross-shore breeze. The second week doesn’t get much better, with maybe a few windows of cleaner conditions on the 12th and 14th of August, but the swell is barely there. This is one of those stretches where it just doesn’t stay poor for long, but right now, it’s poor. Forecasts can change, but I’d be looking at other hobbies for a while.
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.
