Twelve-month study of average temperatures, precipitation patterns, and atmospheric variables
Understand the annual atmospheric rhythm at De Zoom–Kalmthoutse Heide Cross-Border Park through standardized climatological averages. Data encompasses temperature, daily precipitation rates, humidity, wind, and daylight duration recorded between 1991 and 2020 at a specific representative coordinate. These statistics provide a consistent basis for comparing climatic patterns throughout the calendar year.
