Experimental model comparison: lines close together mean higher agreement; spread means more uncertainty. These graphs are informational and do not replace the Surfclub condition score.
Main reading method: model lines close together mean higher predictability; model lines far apart mean uncertainty. Core/model sources are shown as extra baseline lines where available. RWS is shown as observed/reference where available and is deliberately not included in the active-source average. The thick dashed active-source average is recalculated in the browser when lines are switched on/off and is not used in public scoring.
RWS swell/deining is an observed/reference field and may not be one-to-one equivalent to model primary swell. Use this chart as an interpretation check, not as an automatic correction.
Lab-only MeteoBlue wind spread. Wind speed is shown in Beaufort to match the surf/weather reading. Wind direction is shown as a direction-spread chart inspired by Meteoblue: use it to see whether models agree on turning moments, not as a final public forecast.
Collapsed by default. Counts are filled forecast steps after normalization; 5-minute source rows are downsampled to hourly points in charts for readability only.

Lab foundation for comparing Marea Tide and Stormglass Tide at the Callantsoog coordinate with RWS Petten Zuid waterlevel as a nearby reference station. This is source validation only and has no score impact.
Use the range buttons for 1/3/7/14 day windows. Use the slide buttons to move backward/forward through the stored 30-day history and 30-day forecast/reference range. The vertical Nu marker shows the current timestamp when it falls inside the visible window. The RWS line is Petten Zuid reference data and should not be read as exact Callantsoog coordinate tide.
