ABSTRACT: Climate change, primarily driven by human activities, has a growing negative impact on animal health and welfare by modifying environmental variables such as temperature, rainfall, and the frequency of extreme weather events. These factors directly and indirectly affect livestock productivity, promote the emergence of diseases, increase mortality, and compromise food security. The objective of this study was to identify and analyze the relationship between climatic conditions and sheep mortality in the state of Yucatán, as a basis for the design of preventive technologies. Information obtained over four years from necropsies performed on the flock at the Mocochá Experimental Center was used. Data were classified by cause of death, age group, year of evaluation, and quarter (season). The analyses showed no statistically significant differences (P > 0.05) between grouped causes of death and climatic variables such as average maximum-minimum ambient temperature differential (DTAMMP), rainfall (PP), and lunar luminosity level (NLL). However, when considering age groups, lambs were more susceptible to death under high precipitation (P
