Rainfall Variability is one of the key factors that affect agricultural production in any region. Hence the proper understanding of rainfall pattern and its trends may help water resources development and to take decisions for the developmental activities of that place. The present study is an attempt to evaluate the spatial and temporal rainfall variability of Anand district of Gujarat State in Western India. Anand in Gujarat State popularly known as the milk capital of India is located in the Southern part of Gujarat near Gulf of Cambay. The district has eight Talukas with district headquarter at Anand. Khambhat Taluka of this district has natural border with Gulf of Cambay. The normal rainfall of this district is 687mm from South-West Monsoon with an average of 40 rainy days. The normal onset of monsoon is from 3rd week of June and the normal cessation is in the 4th week of September. In the present study the spatial and temporal rainfall characteristics of this district are studied. Long-term annual and monthly rainfall data (Monsoon months) are considered from 1901 to 2014. The daily rainfalls of monsoon months of all the eight Talukas are analysed for the last five years from 2010 to 2014. It was found out that spatial and temporal variability is high in the District.
