January was significantly warmer and drier than average. Rainfall amounts in January were very low, making it one of the three driest Januarys on record in Israel (alongside January 2014 and 1955). In northern Israel, only a few millimetres of rain fell, even in typically wet areas like the Galilee and the Golan Heights, where the long-term monthly average is 150–250 mm. This makes January 2025 the driest January in these regions since measurements began. Central and southern parts of the country experienced slightly more rainfall, but even there, January 2025 was among the driest ever recorded.

As a result of the dry January, cumulative rainfall since the beginning of the season is also significantly below average. This is especially notable in the north-eastern parts of the country, the Judean Hills, and the Negev, where totals amount to about one-third of the seasonal average.

January was also warmer than average, ranking second after January 2010. Daytime temperatures stood out, being about 3°C above average nationwide, despite there being no days with exceptionally high temperatures. The high daytime temperature average resulted from many clear days during the month. Such a persistent lack of cloud cover is rare even in dry winter months. On the other hand, the clear skies contributed to stronger radiative cooling at night, leading to minimum temperatures in flat and elevated areas being around or only slightly above average, despite the absence of cold rain systems from the north and despite consistently above average upper atmospheric temperatures.
