India, a subtropical country is highly sensitive to climate change and its variability. The main reason for its high sensitivity is the variability in rainfall and temperature. About 80 percent of the total rainfall over India occurs during the four months from June to September as a result of the southwest monsoon. With this background, present study was conducted in marathwada region of Maharashtra to examine spatial and temporal variability in climate variables. The result shows that variation in seasonal rainfall was found more in post-monsoon period followed by pre-monsoon and monsoon period.The average rainfall was highest in August month. June and October rainfall over the years has decreased sharply while, august and September rainfall has increased. The principal rainstorm months are not contributing as normally. From an agronomic point of view dry spells at critical growth stages can be extremely hazardous and it is one of the prime reasons for dwindling crop yield. Analysis of trend in climatic variables reveals that Marathwada region is more affected with change in frequency of rainfall, less number of rainy days and frequent dry spells.
