Around 2250 ha will be developed from the agricultural point of view in Chone, province of Manabí, Ecuador, in the second stage of one of the emblematic and strategic projects of Ecuador, known as Multipurpose Chone. For this purpose, climatic and soil parameters, water availability, crops, etc. are required. This paper makes a contribution in the climatic branch. The monthly distributions of precipitation and evaporation are determined for the subsequent calculation of the crops irrigation regime. A statistical analysis of precipitation and evaporation data from 1990 to 2012 is accomplished, and as a main result is obtained that 2005 is the one meeting the 75 % of surpass probability for rainfall and 25 % for evaporation..
