The Lowdown
Alright, folks, let’s call a spade a spade. This here forecast is a tough one. We’re looking at a two-week stretch that's mostly flat and messy, with no real gold at the end of the rainbow.
Right now, we’ve got nothing. Monday the 14th has a tiny 0.1m of weak north swell, but a cross-shore wind is making it a total mess. The water’s 67°, which is much warmer than it should be this time of year, but you’ll be doing more floating than surfing. Tuesday and Wednesday don’t get any better – small waves, short periods, and onshore winds. It’s a write-off.
We go through a dry spell from Thursday the 17th. We start seeing a bit more energy, hitting around 214 by Thursday afternoon, but it’s still rough. A 1.7m WSW swell comes with strong cross-shore winds, so it’s a washing machine. Friday, Saturday, and Sunday keep that same theme – some chest-high sets, but the wind keeps shifting, and the periods stay short. Nothing clean.
We get a glimpse of something better on Sunday the 21st. The wind turns offshore, the water gets glassy, but the swell is a tiny 0.8m from the NNW with a 7-second period. You might get a few ankle-biters on a longboard, but that’s about it.
Then the tease. Monday the 22nd and Tuesday the 23rd bring our best swell of the period. On Tuesday, we see 1.9m from the NW with a 9-second period, and the combined energy jumps to 572. That’s real surf. But the wind is onshore or cross-onshore, completely ruining the shape. It’s frustrating as hell.
After that, it drops off a cliff. Wednesday the 24th has some leftover NNW swell, but it’s choppy. From Thursday the 25th onwards, it’s flat. By Saturday the 26th, the ocean is a sheet of glass with offshore winds – perfect, but with zero waves. The ultimate tease.
So, what do we do? We wait. This is a genuine blank run for Blokken. No standout days, no hidden gems. The kites will have a field day on the windy, choppy days, but for us surfers, it’s a wash. The one day with real potential, Tuesday the 23rd, gets destroyed by wind. It’s a rare stretch of nothing for this spot.
Keep your boards waxed and your eyes on the charts. These things change.

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.
