The Lowdown
Alright, Rusty here. Let’s talk Blokken through the next couple of weeks.
Honestly, it’s looking like a lean stretch. The first surfable pulse shows up Monday, September 7th, but it’s only 1ft from the NNW with a weak 7-second period. Combined swell energy is only 13—barely a ripple. The water is sitting at 69°F, which is *much warmer than normal* for this time of year, nearly 5° above average, so you won’t need a steamer.
That first week is rough. From Monday through the middle of the month, we see a few knee-high to waist-high pulses, but the wind just won’t play ball—cross, cross-on, onshore. The only clean window is Thursday morning, September 10th, when you get 0.8m (about 3ft) from the NNW with a 6-second period, but the energy is only 47. Not worth the drive.
There’s a solid gap of several days where you might as well leave the board in the car.
The one bright spot is shaping up for Sunday, September 20th. On that morning, a 1.6m (5ft) WNW swell rolls in with a 6-second period and combined energy of 198. The wind goes cross-offshore out of the SW, keeping it clean. The swell direction is a good match for Blokken’s sweet spot (NNW). That afternoon, the wind drops to a light 20 km/h (12 mph) cross-off, and the waves will be clean and fun. The water is still warm, and the waves will be consistent enough for a decent session.
But remember—Blokken is an inconsistent spot, so any good day here is a rare treat. It’s a beach break, so when the swell period gets longer (like the 8-9 second NW pulses on September 21st), those waves might break a bit too straight. For an intermediate surfer, that Sunday is the only real option.
After that, the final days get ugly—bigger swell but blown out by strong onshore winds. September 21st pumps out 8ft with 8-second period and combined energy of 762, but with onshore wind and a beach break, that’s expert-only or kite-surfing territory.
So, to put it simply: the forecast is a long wait for one clean day. Sunday, September 20th is your best shot—waist-high, clean, warm, and cross-off. Don’t expect much else.
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.
