The Lowdown
Alright, let’s get real about the surf. I’ve been staring at the charts for Blokken, and to be honest, it’s a bit of a tough stretch. We’ve got a solid run of days where the ocean just isn’t playing ball for us paddle surfers.
The pattern starts with a little pulse of swell, but the wind is messy. Tuesday the 15th has a little waist-high WSW swell with a short period of 4-5 seconds, but it’s cross-off in the morning, which cleans it up a touch. Still, it’s weak, with the energy reading a paltry 33, and it’s pretty gutless. The afternoon turns cross-on and choppy, so that’s out.
Wednesday the 16th sees a bump in size to chest-high with WNW swell, but the period is still short, around 5-6 seconds, and the wind is on it or cross-on. The energy is moderate, 67-91, but it’s messy and lumpy with poor conditions. Not worth the paddle.
Now, Thursday the 17th is where it gets interesting, but not for us. The swell builds to 5ft in the morning and 6ft in the afternoon, with a strong SW wind at 25-28 mph. That’s a strong cross-shore, making it a complete washing machine. The energy bumps to a moderate 146 and 268. There’s some size, but with that wind and the short, weak period (5-6 seconds), it’s not a surfer’s wave. A setup like this, a beach break with strong winds and messy chop, is honestly looking more like a kite surfer’s plaything than a place to paddle out.
We get a little respite on Friday the 18th with a drop to 5ft and 5ft, but it’s on the cross-on shore with a fresh 22 mph breeze, keeping it lumpy and generally poor. The energy is still moderate (121-126), but the quality just isn’t there.
The weekend is a big letdown. Saturday the 19th starts with a morning of cross-shore winds and 5ft swell, but it drops off quickly. It’s still messy with a strong breeze. The energy is moderate (128), but the period is still a weak 5 seconds. Saturday afternoon and all of Sunday drop way off, with the swell fading to 2ft and then 1ft. The model shows some onshore wind, but the energy is weak, just 27 and 17. It fades into the early part of next week, with the swell bottoming out to 1ft and 0.7ft, with energy readings dropping to single digits. There’s a long stretch there with nothing to get excited about.
The only bright spot is that the water is running warm. On the first day I mentioned, the temp is 68°, which is a full 5° above normal for this time of year. That’s notable, so at least you won’t need a thick suit while you’re sitting there watching the flatness.
The models do show a small blip later on the 25th and 26th, but it’s still tiny – 1ft to 2ft. The energy is weak, but there is a clean cross-off wind on the 26th that might make for a glassy, if gutless, morning. That’s about as good as it gets.
Looking further out, there’s a hint of some longer-period swell arriving on the 30th. It’s got a 14-second period, which is great in theory, but the swell height is only 0.7ft. It’s a promise, not a reality.
Honestly, for the next two weeks, there’s nothing here that gets the heart racing. It’s a flat spell for Blokken. The water’s warm, but there’s nothing to ride. I’d keep the board waxed and the fins ready, because with that warm water, things can change, but right now, it looks pretty bleak. We might get a few knee-slappers, but nothing worth calling in sick for.

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.
