The Lowdown
Alright, let's get into it. The outlook for Blokken is a rough one. The whole sixteen-day window is pretty much a write-off, to be honest. There's barely a wave worth paddling for, and when there is a tiny bump, the conditions are just not cooperating. The water is sitting at 72°F currently, which is much warmer than normal for this time of year, but that's about the only upside.
First up, Tuesday the 18th of August. We've got a weak, short-period 4ft swell from the west, but a fresh cross-onshore wind is ruining it. The combined energy is a measly 58, and it's just lumpy and poor. That sets the tone for the next few days. Through Wednesday and Thursday, the swell stays small and weak, maxing out at a combined energy of 84 on Thursday morning, but with fresh cross-shore winds and rain showers, it's all chop and no hope.
Now, Friday the 21st of August morning, we see a tiny 1.0ft NW swell with glassy conditions – that sounds good, but with a combined energy of only 19, there's simply no wave to ride. The afternoon picks up a bit to a 3ft NW swell with moderate energy (117 in the brackets), but it's choppy again.
Saturday morning the 22nd of August is the one brief moment where it's almost surfable. A clean, glassy 2ft NW swell with a combined energy of 67. The guidance says it's "surfable waves but very ordinary conditions," but honestly, for a 2ft wave, you'll be struggling. After that, the forecast goes completely flat for days. From Sunday the 23rd all the way through to Monday the 31st of August, there are spells of clean offshore wind, but the swell heights mostly stay below 2ft and the combined energy is nearly always below 50. It's a long, dry stretch.
The only thing that looks remotely interesting is way out on Tuesday the 1st of September. A 7ft WSW swell rolls in with a combined energy of 412 – that’s a proper amount of water moving. But here’s the kicker: the wind is a fresh cross-shore at 22 mph, which will make it a lumpy, choppy mess. At that size, it’s pushing into expert territory (over 8ft is for experts only, so 7ft is big but manageable for experienced surfers), but the wind just kills it. The period is a short 7 seconds, so it won't have any real push. It looks more like a kite-surfing day than a paddle-surfing one. The following days have some clean wind on smaller swells, but the quality is still rated as poor right to the end of the forecast on Wednesday the 2nd of September.
To sum it up: there are no good surf options in this entire 16-day window. Blokken is a spot that can be inconsistent, and this is one of those blank runs. It tends not to stay poor forever, but this stretch is a dud. Keep the board in the car and the expectations on the floor.

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.
