January 2025 brought relatively mild conditions to the Netherlands, with temperatures hovering close to seasonal norms throughout the month. The average temperature across the country reached 3.4 degrees Celsius, just 0.2 degrees below the normal value of 3.6 degrees. This near-normal pattern was punctuated by notable extremes, with the warmest day recorded on January 6 in Echt-Susteren, where temperatures climbed to 13.1 degrees Celsius. In stark contrast, the coldest conditions emerged on January 14 in Vaals, where the mercury plummeted to minus 11.4 degrees Celsius, creating a substantial temperature range of over 24 degrees between the month's warmest and coldest locations.
Precipitation levels exceeded seasonal expectations during January, with the country receiving an average of 99.0 millimeters compared to the normal 85.8 millimeters, representing a 15 percent surplus. The wettest single day occurred on January 5 at Goeree-Overflakkee, where 28.3 millimeters of rain fell. Over the entire month, Maastricht emerged as the wettest location, accumulating 152.6 millimeters of precipitation, significantly above average for the region. This elevated rainfall contributed to wetter-than-normal conditions across much of the country.
Sunshine hours fell slightly short of expectations, with 103.9 hours recorded against a normal value of 112.0 hours, representing a 7 percent deficit. This reduction in sunshine was typical for winter conditions in the Netherlands, where shorter daylight hours and increased cloud cover during the season limit solar radiation reaching the surface. The combination of near-normal temperatures, above-average precipitation, and slightly reduced sunshine characterized January 2025 as a fairly typical winter month for the Netherlands, with conditions remaining relatively balanced despite some regional variations in both temperature extremes and rainfall distribution.
