The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The 16-day window for Katwijk aan Zee is a tough one. There’s no surf worth chasing. The first record that shows any activity is on Tuesday, July 21st, but even then, the swell is tiny and the conditions are messy. We’re looking at a long, flat spell with nothing that’ll get you out of bed.
The wind is mostly onshore or cross-onshore for the first week or so, and the swell is weak. The combined energy barely cracks 100 (29), and it’s a short-period, bumpy mess. Even on Friday, July 24th, when it goes glassy in the morning, the swell is only 2ft from the north with a 7-second period, and the energy is just 33. It’s clean but not surfable.
By the end of the second week, we get a little spike in wind direction from the east on Friday, July 31st, giving us clean, cross-offshore conditions. The swell is still tiny though – 2ft to 3ft from the north-northeast. The waves will be small and weak, with a period of just 4 to 5 seconds. It’s clean, but not really enough to get excited about.
This is a blank run. Katwijk aan Zee is an exposed beach, and when the swell is this small and the wind is this bad, it’s a lake. A few days in the second week might offer a clean surface, but there’s simply no power behind it. For a spot like this, a run of poor surf is normal. The water is about average for this time of year, but you won’t even be in it.
Rusty.

Information about the Katwijk aan Zee Surf forecast
The above surf forecast table for Katwijk aan Zee provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Katwijk aan Zee can be found by selecting the local surf guide option on the grey menu. Our Katwijk aan Zee 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 (Katwijk aan Zee) 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 Katwijk aan Zee 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.
