In order to characterize variables and relevant meteorological phenomena that affect inland aquaculture, reservoirs from Villa Clara and Santiago de Cuba province were selected. To determine the influence of the variables, water temperature (oC) and oxygen concentration (mg • L-1) were studied at different depths and from the meteorological point of view, extreme air temperatures (maximum and minimum) (oC), average air temperature (oC), relative humidity (average daily, extremes) (%), cloudiness (eighth of covered sky), accumulated precipitation (mm) and wind speed (m • s-1). The thermal ranges of the commercial species clary (Claria gariepinus), tilapia (Oreochromys and Tilapia), tench (Tinca tinca L.) and carp (Cyprinus carpio L.) were considered. It was observed that the meteorological phenomena with greater negative impacts resulted in heavy rains and drought. Water temperature ranges suitable for the development of the four species were presented. In addition, it was found that this variable has a positive association both with the air temperature (extreme and medium) and with the accumulated rainfall. A negative correlation was also observed between the relative humidity of the air (extremes and means) and the wind speed.
