The Lowdown
Alright, let's get real for a minute. The next couple of weeks are looking pretty grim for a paddle. We’ve got a big fat hole of nothing at the start, so don't bother waxing up just yet.
Starting Thursday the 20th of August, it's a write-off. There’s some 4ft swell from the WSW, but it’s getting torn up by a fresh cross-shore wind. Total junk. Friday and Saturday keep that 4 to 5ft of NNW swell, but the wind is cross-on and messy. Not worth the drive.
The following week, the wind cleans up a bit with some light offshore breezes, but the swell completely disappears. Monday the 24th has a weak 2ft N swell, and it shrinks from there. By Wednesday the 26th, you're looking at knee-high slop of about 0.6ft to 1ft. The combined energy is in the single digits, so it’s basically a swimming pool. That dead run goes from Thursday the 20th all the way to the end of August. You'll be surfing sandbars.
The first few days of September don't offer much either. The 1st and 2nd have some 3 to 3ft WSW swell, but the wind is onshore or cross-on, keeping it choppy and unappealing.
But hold on. Friday the 4th of September is the one to circle on the calendar. We’re looking at a solid 8ft swell from the WNW, with combined energy hitting 644 – that's a proper pulse. And the wind is set to be blowing clean offshore from the south. At *Blokken*, that size is strictly for the experienced crew. 8ft on an exposed break is no joke. It’s a long way out, so forecasts can change, but if it comes together, that’s the only real session in this whole outlook. The swell direction isn't perfect for Blokken, but clean offshore wind on a big swell is a recipe for something special, even if the waves might be a bit straight. For everyone else, it’s a waiting game.
So to sum it up: the next two weeks are mostly a bust. The only real, serious surf is that big, clean groundswell on the 4th of September for the experts. The rest of us are on a beach holiday.

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.
Blokken is 10 km (6 miles) from Hoek Van Holland. If you plan a holiday in Netherlands, look for hotels and other accommodation in Hoek Van Holland. Hoek Van Holland has rooms for a wide range of budgets as well as car hire and transport links.
