The Lowdown
Right, grab a seat, let’s have a look at the next couple of weeks for Blokken.
Honestly, for the first week and a half, it’s a bit of a write-off. The surf is mostly small, messy, and the wind is all over the shop. The swell is short-period, weak, and the wind is either cross-onshore or onshore and strong, making for poor, choppy conditions. The water is a crazy 8°F warmer than usual for this time of year, which is very unusual, but you won’t be caring about that when you’re staring at a bumpy, flat lake.
The first real glimmer of hope comes on Sunday the 26th of July. The morning session is our standout. It’s not big, but it’s the only time the stars align. We’ve got a 6ft swell from the WSW, with a period of 6 seconds. The wind goes completely glassy calm, which is a major positive. The combined energy is moderate (224). It’s the only time in the whole run that’s worth paddling out. The rest of that day, the wind picks up and ruins it.
After that, it’s back to the same story. Through the end of July and into the first week of August, the swell drops off to barely anything, and the wind is mostly onshore or cross-shore again. The energy values are all in the double digits, which is weak. There’s a brief moment on Sunday the 2nd of August morning with a light, cross-offshore breeze from the south, but the swell is only 3ft from the west with a period of 5 seconds, so it’s pretty weak. It’s clean, but don’t expect much.
So, the final call: For most of the 16 days, you’re looking at a long, blank run of poor surf. It’s just one of those periods for the area. The only real chance to get wet is the morning of Sunday the 26th of July at Blokken. If you’re not out that morning, you can probably leave the boards 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.
