Oxygen isotope ratios in Holocene stalagmites decrease systematically in an easterly direction across Europe, reflecting zonal flow and progressive rainout. ► Speleothem δ18O longitudinal gradients decrease gradually during the course of the Holocene. ► Speleothems from Mediterranean-influenced cave sites exhibit higher δ18O values than those predicted by the regional longitudinal trends. ► δ18O in speleothems deposited in high elevation sites are lower than those predicted by the regional longitudinal trends. ► The first-order δ18O variability in European Holocene speleothems can be predicted from time-dependent linear regression models.
