The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
First off, I gotta be straight with you – this is a tough stretch for Blokken. The whole 16-day window is pretty much a flat spell with no real surf to get excited about. The combined swell energy barely cracks double digits most days, and when it does get a little bump, the wind and conditions just trash it. We’re looking at a long gap of poor surf that stretches from now until the end of the month. It’s one of those periods where you’re better off checking the forecast again in a few days, because things can change, but right now, it’s a write-off for paddle surfing.
The only time the ocean shows a bit of life is around Wednesday the 19th and Thursday the 20th. On the 19th, we get a pulse of swell from the WSW pushing 7ft, but the period is a short 6 seconds – that’s windswell, not groundswell, and it’s gonna be messy. The combined energy jumps to 348 (moderate), but the wind is howling onshore from the NW at 16 mph, so it’s just a lumpy, blown-out mess. That’s expert-only territory at that size, and even then, it’s not gonna be pretty. Next day, the 20th, still has some energy (171), but it’s the same story – fresh cross-onshore winds and lumpy conditions.
Later on, around Thursday the 27th, we get a clean window with cross-offshore winds from the SSW at 12 mph and a 5ft swell from the WNW. That’s the closest we get to something rideable, but the combined energy is only 98, so it’s weak. Still, the clean wind could make a few fun ones if you’re desperate. But honestly, for a spot that’s exposed to a NNW optimum, the swell direction is all over the place and never really locks in.
No standouts here. No real waves to sink your fins into. The water temp is about average for the time of year, so no surprises there. If you’re a kite surfer, the strong winds and chop on the 19th and 20th might look more interesting than the paddle scene. For the rest of us, it’s a waiting game.
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.
