The study was setting up in fourteen sugar mills from Artemisa, Mayabeque and Matanzas provinces, with its associated meteorological stations. Annual sugarcane field yield (RA) and Industrial yield (RI), besides records of monthly maximum temperature (Tmax), minimum (Tmin), (Tm) and precipitation (Prec) in the period between 1980 and 2011 (30) were the basis for this research. The data analysis revealed that throughout the period, Tmax was unchanged, Tm increased in 0,93ºC while Tmin did in 0,62ºC and thermic oscillation (AT) fell 0,72ºC. Meteorological station of Bahia Honda displayed the lowest AT value. The rainfall increased in 33.78%, while RA decreased 52.83% compared to its initial value. An inverse dependence between AT and Tmin was found, while there was a strong dependence between RI and Prec (97%) in all provinces. These last 10 days before harvest, had a negative effect on RI, while this was not practically affected. It was concluded that Matanzas was the province with the best climate conditions for sugarcane cropping and within the area the most favorable for its development was Jovellanos.
