The Lowdown

G’day, I’m Rusty, and I’ve been staring at the charts for Blokken over the next couple of weeks. Honestly, it’s a pretty grim run. The forecast shows no decent surf on the cards—everything that pops up is fighting poor conditions, with not a single recommendation worth paddling out for. The water’s sitting at 71°F, which is a solid 6°F warmer than usual for this time of year, so that’s a real oddity, but it doesn’t make up for the lack of waves.

We start off Wednesday the 19th with tiny, weak swell around 2 ft from the WNW, but the wind’s onshore and messy, and the combined energy’s a pathetic 17—barely a ripple. That theme sticks through the weekend. By Thursday the 20th, there’s a bit more push with 5 ft swell from the WSW, but it’s cross-shore and lumpy, with energy still only hitting 119. Friday and Saturday see a shift to NNW swell, but the wind’s still onshore or cross-onshore, and the waves are small and choppy. On Sunday the 23rd, the swell drops to 3 ft, and the period’s up to 8 seconds, but it’s still cross-onshore and messy.

We get a few clean moments early next week—Monday the 24th and Tuesday the 25th have offshore winds and clean conditions, but the swell’s tiny, like 2 ft to 2 ft, with energy in the 20s and 30s. Not worth wetting a wetsuit for. Later in the week, the wind’s all over the place, bouncing between cross-off and cross-on, but the swell’s still small and weak. By Friday the 28th, there’s a spike to 6 ft from the NW with energy at 293, but it’s cross-onshore and lumpy, so it’s ugly.

The first few days of September see a real jump in size—Tuesday the 1st has 4 ft but it’s messy, and then Wednesday the 2nd pumps up to 10 ft from the WNW with energy at 953. That’s a solid wall of water, but it’s cross-onshore and lumpy, making it a challenge for experts only. Thursday the 3rd drops to 6 ft from the NW, still not clean. All through this, the rating’s a zero for every single window—poor surf conditions every time. Blokken is inconsistent at the best of times, and this stretch is a real dud. If you’re itching for something, the wind and chop on those bigger days might make it more interesting for kite surfing than paddle surfing. Forecasts can change, but right now, there’s nothing to get excited about.

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.
