The present study focus on a statistical approach for improving climate prediction for the region of the Bouregreg basin in the northwest of Morocco. The aim was to examine the past drought conditions and to find their trend under climate change conditions. Past and future drought conditions were assessed using Standard Precipitation Index (SPI) by considering the emission scenarios A2 and B2 for three periods 2014-2040, 2041-2070 and 2071-2099. A statistical downscaling method was applied to the HadCM3 outputs for the station of Rabat to simulate the projected changes in precipitation and temperature. Results shows that annual precipitations under A2 scenario increased by 4.72 %, 4.75% and 4.50 %
