The Lowdown

Alright folks, Rusty here. Let’s take a hard look at what’s on offer for the next couple of weeks.

Honestly, it’s a pretty grim stretch ahead. The only break in the game is Blokken, and it’s a tough one to call – it’s an inconsistent spot, so a blank run like this is more normal for the area than a spectacular run of swell. The first few days are a write-off. We’ve got a bit of a pulse on the 5th, but it’s messy, windy, and the water temp is sitting at 69°, which is a whopping 5° warmer than usual for this time of year – that’s a very notable anomaly.

The real pain is the wind. From Saturday afternoon (5th September) through the whole of the following week, it’s a constant battle of onshore, cross, and cross-off breezes, never giving us a clean window. The one standout moment comes on the morning of Thursday, 10th September. The wind drops to glass from the ENE at just 3 mph, and we get a clean, 3 ft swell from the NNW with a period of 7 seconds. The combined energy is weak (65), but it’s the only time the ocean looks like a surf spot. That’s the best on offer – a small, clean, glassy session for the intermediate crew. The 3 ft height is small enough for beginners, but the inconsistency of the break makes it more of a challenge.

After that, there’s a massive gap. The next semi-decent window doesn’t arrive until the weekend of the 19th and 20th September. The morning of Saturday, 19th September, shows another glassy window with a 2 ft swell from the NNW, but it’s a week and a half away, so while it’s promising, it’s less certain. The energy is still low (58). The following Sunday morning (20th) has a clean, 2 ft swell from the N, but it’s a tiny wave.

Overall, the best wave of the whole 16-day window is that Thursday morning glass-off. It’s not a classic, but it’s clean. For the rest, you’re looking at kitesurfing conditions or just staying home.

Rusty.

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.
