Abstract : This work exposes the spatio-temporal frequency of seasonal drought in Gharb, a leading agricultural region in the Northwest of Morocco. It is based on the monthly approach of the report precipitation-temperature. The report P < 2T shows that the summer drought is regularly present each year and its length varies from one year to the next. Drought can also accidentally set other seasons of the year.In Gharb, the dry months recorded a trend to decline or stagnation following the stations. This translates into a tendency rather to both rising temperatures than precipitation. However, the definition of drought based on temperature and precipitation parameters does not have the slightestmathematical justification, since it establishes the link between quantities of different nature. On the other hand, water balances, calculated from the confrontation of precipitation and potential evapotranspiration, emphasize drought in terms of water deficit. Potential evapotranspiration is rarely measured with reliability in Gharb, particularly in the studied sites.
