El Nio developed during the summer of 2023, but the western Pacific experienced a below average year in Tropical Cyclone (TC) activity with only 19 TCs developing. This, along with a quick return of a dry trade-wind pattern in December of 2023, led to below average rainfall from much of Micronesia. This drier pattern continue through January as the dry phase of El Nio began.
