In Villa Clara province, Cuba, microorganisms and climatic conditions coexist for the development of the infectious entity chromoblastomycosis. Besides, there is a high percentage of agricultural and handicraft workers exposed to acquiring this infection. The objective of the research consisted in describing the etiological diagnosis and correlating chromoblastomycosis with average climatic variables of the meteorological stations located in Villa Clara. Between 2018-2022, a descriptive, cross-sectional study was conducted in a population of 25 patients diagnosed with chromoblastomycosis by anatomopathological and microbiological studies. Absolute frequencies were used as a summary measure, and for correlation with climatic data from the five meteorological stations, inferential statistics. Of the total number of patients, 92% were diagnosed by anatomopathological studies and only 2/8% had mycological studies, in which the species Fonsecaea pedrosoi was isolated. There was a significant correlation between mean temperature (p=0.045) and mean predicted wind (p=0.028) and the number of cases. This was not the case with relative air humidity (p>0.05). It is concluded that in Villa Clara province, only the etiological agent F. pedrosoi was the cause of the disease during the period studied, with a significant relationship between the disease and the average climatic variables mean temperature and mean predicted wind.
