The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, I gotta be straight with you – this stretch is a tough one for waves. We’ve got a long gap at the start with nothin’ worth paddlin’ out for. The first real window of surf doesn’t really show up until Sunday morning, the 6th of September, and even then it’s a pretty small offering.
The overall pattern is dominated by onshore and cross-shore winds that are just wreckin’ whatever swell tries to push in. There’s a lot of lumpy, choppy, and messy conditions, especially through the first week. The water’s been runnin’ warm, about 69°, which is much warmer than usual for this time of year, so that’s a nice bonus if you’re just dippin’ your toes, but it don’t make the waves any better.
The one spot we’ve got to talk about is Blokken. It’s an exposed, inconsistent break that needs a good swell direction from the NNW to work, and it’s an intermediate level wave. The crowds are *sometimes* a factor, so you might not be totally alone out there.
Let’s run through the days.
Sunday morning, 6th September – This is the first little blip. We’re lookin’ at a tiny 2ft swell from the NNW, with a period of 8 seconds. The wind is a moderate offshore from the SSE, so the surface will be clean. The combined wave energy is weak (54). It’s surfable, but very ordinary. If you’re desperate to get wet, you could, but it’s not gonna be a day to remember.
Sunday afternoon – The swell drops even more, to 2ft. The wind goes light cross-offshore. Clean, but barely a ripple.
Monday 7th – Not much happens. A tiny 1.0ft pulse in the morning with clean offshore wind, but it’s really just a flat spell. The afternoon shows a weak 3ft of short-period windswell from the WSW, but the cross-shore wind makes it a bit lumpy.
Tuesday 8th and Wednesday 9th – Things get a bit more active, but the wind is a mess. We see some pulse up to 6ft from the WNW with a period of only 6 seconds – that’s short period, wind-driven junk. The wind is strong cross-onshore, so it’s just a lumpy, strong onshore mess. The energy gets up to moderate levels (238 and 223), but with those winds, it’s a no-go for a decent paddle surf. This setup would be way more fun for a kite surfer than a surfer.
Thursday 10th – The swell drops back to 3ft, and the wind is still cross-shore. Not great.
Friday 11th – Another messy day with cross-onshore winds and a weak 3ft to 4ft swell.
Saturday 12th – The swell bumps up again to 6ft from the WNW, with a short 6-7 second period. The wave energy is strong (271-327), but again, the cross-onshore wind is just kickin’ up chop. Another day for the kite crew.
Sunday 13th – Still a 6ft swell from the NNW, but the wind is a cross-onshore. Too choppy for good surfing.
Monday 14th – The swell drops to 2ft. The wind turns light cross-offshore in the morning, so it’s clean, but the waves are tiny.
Tuesday 15th afternoon – This is actually the best on offer for the whole two weeks. The swell is 3ft from the west, period a short 5 seconds, but the wind goes glassy. That’s a major positive. The energy is low (79), but if you get out there on a longboard, you’ll find some clean, small waves with no wind to fight. It’s not a standout because of size, but for the conditions, it’s the pick of a very poor run.
Wednesday 16th onwards – It’s all downhill again. The swell drops and the wind stays onshore or cross-shore. By Saturday 19th and Sunday 20th, we’re talkin’ flat – 0.7ft to 0.3ft swells. The run from 16th to 20th September is a real dead zone, with no surf of any note.
So, if you’re lookin’ for a wave, the best chance you’ve got is to aim for Tuesday 15th afternoon at Blokken when that glassy wind hits. It’s small, but it’s clean. The rest of the time, you’re better off doin’ somethin’ else, or just acceptin’ it’s a flat spell through the second week.

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.
