December was rainier than average in most parts of the country, with the exception of the northeast. The southern regions were particularly notable, ranging from the Southern Coastal Plain to the Negev and the Arava, where precipitation totals reached two to three times the average, and in some instances, even higher. Conversely, in the Upper Galilee, the Golan Heights, and the Hula Valley, monthly rainfall accumulations were slightly below average.

During the first part of the month, the "Byron" system passed through, bringing heavy rainfall primarily to the coastal region. However, significant precipitation systems occurred throughout the remainder of the month, resulting in a high number of rain days, ranging between 13 and 16. Following the rainfall, urban flooding occurred, as well as flash floods in the eastern and southern streams.

Despite being wet, December was warmer than average. While temperatures during the rainfall episodes were cooler than average, the deviation was not significant; however, the intervals between these episodes were considerably warmer than average. This was particularly evident during the warm spell at the beginning of the month, which constituted a continuation of the exceptionally warm November.

This concludes the year 2025, during which most months were warmer than average. Consequently, the year ended considerably warmer than average and is ranked fifth since records began.
