Planktonic foraminiferal Mg/Ca and δ 18 O derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long‐term cooling and freshening trend, as well as considerable centennial‐scale variability during the last millennium. The warmest temperatures and highest salinities occurred during the Medieval Warm Period (MWP), while the coolest temperatures and lowest salinities occurred during the Little Ice Age (LIA). These changes in the western Pacific, along with observations from other high resolution records indicate a regionally coherent southern displacement of the Inter‐tropical Convergence Zone during the LIA, with more arid conditions in the northern tropics and wetter conditions in the southern tropics.
