Adam Clarke on Jeremiah 14:1

The word - that came - concerning the dearth - This discourse is supposed to have been delivered, after the fourth year of Jehoiakim. Concerning the dearth. We have no historic record of any dearth that may fall in with the time of this prophecy, and perhaps it does not refer to any particular dearth: but this was a calamity to which Judea was very liable. They had ordinarily very dry summers, for scarcely any rain fell from April to the middle of October; and during much of this time, the rivers were generally either very low or entirely dry. They kept the rain of the winter in tanks and reservoirs; and if little fell in winter, a dearth was unavoidable. See an account of a dearth in the time of Elijah, 1Kgs 18:5, through which almost all the cattle were lost.
