The Lowdown
Alright mate, gather round. Looking at Blokken, the water is a weirdly warm 69°F right now, well above what you’d expect. I’ll cut to the chase: there’s nothing good coming in this 16-day window. Not a single surfable day.
It starts on Saturday, August 29th with a lumpy, cross-shore mess. We’ve got 1.6m swell at 6 seconds, but with 22 mph crosswind, it’s just ugly. The combined energy is 226 (moderate) but it doesn’t matter. Sunday the 30th is worse with strong cross-onshore wind, and Monday the 31st shows a 2.1m west swell, but with 28 mph cross-onshore, it’s pure chop. The energy hits 466 (moderate to strong), but for a beach break with that wind, you’re wasting your time.
The whole first week is a write-off. Tuesday the 1st of September drops to tiny 0.7m mush. Thursday the 3rd brings a 1.8m swell (266 energy), but again, 25 mph cross-onshore keeps it terrible. Saturday the 6th has a 2.2m swell (505 energy), but with fresh cross-onshore, it’s more of a kite session than a surf. There’s no clean option to recommend.
The second week is completely dead. We see a few mornings with cleaner cross-offshore wind around the 7th and 10th, but the swell is barely 0.6m, with energy under 40 (weak). It’s flat. From the 11th of September, the swell drops to 0.2m – that’s a swimming pool. The blank run carries on right through.
Nothing stands out. The break is inconsistent and the swell direction never lines up. For Blokken, a run like this is just normal. You’ll have to sit this one out.

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.
