Juliandorp faces W, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow kite surfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is offshore at 12 kn. Offshore is the one to be careful with for kite surfing — a failure blows you away from the beach, so it is a spot for a safety boat or a change of plan rather than a solo session.
Over the published window Juliandorp clears 60/100 for kite surfing at every ability from Beginner to Expert — an unusually broad spot, which normally means a range of conditions rather than one narrow sweet spot. Today, 10 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Juliandorp ranks 14th for kite surfing. The order changes by discipline: the same conditions that put a spot top for one sport can drop it down the list for another.
Satellite-derived bathymetry with 10 m pixels and 10 cm vertical resolution out to ~40 m depth. The shape of the seabed is what determines where and how waves break.
Most apps run a single global model at 9–25 km. We blend regional NWP from national meteorological offices at 1.3–2 km — UK Met Office UKV, Météo-France AROME HD, ItaliaMeteo ICON-2I — with ECMWF IFS for the 8-day horizon. Finer resolution means the sea breeze, cliff funnelling and bay shadowing that changes everything for a session.
A nearshore wave model propagates the spectrum across the bathymetric mesh — modelling refraction, shoaling, dissipation, focusing and breaking as it goes. Most apps stop at swell + wind. We go further.
10 sport models × 4 ability levels weight wave height, period, wind, tide and breaking conditions differently — calibrated against ridden sessions so the scores mean what they say.
A sandy North Sea beach shaped by stone groynes: flat water between them suits freestyle kitesurfing, while swell brings beach-break waves for surfing and wave-kiting. Groynes become a submerged hazard at high tide, so entry and exit is safest at low tide. A nudist zone lies south; dogs must be leashed 1 May–1 October. Lifeguard cover runs from a main post, weekends in June and September, daily in July–August. Tidal range is around 1.5 m.
