    Water is the most important thing in our life. Therefore, the lack of water (deficit) will be very harmful to all living creatures and it is almost certain that water deficit areas will experience drought. Water deficit can be caused by El Nino. In 2015, El Nino is listed at an intermediate level moving towards a strong level. Bima region, West Nusa Tenggara is one of the affected areas of El Nino. Therefore, it is interesting to study the availability of soil mosture in the area. The availability of soil mosture can be measured by a water balance analysis. The study was conducted using rainfall data and temperature from meteorology station Sultan Muhammad Salahuddin. Rainfall and temperature data are averaged over the El Nino period in 2015 to make land balance calculations yielding surplus and deficit data. The supporting data in atmospheric dynamics analysis using sea surface temperature data were processed using GRADS, wind data, and Southern Osilation Index data obtained from BOM (Bureau Of Meteorology, Australia). The method used is the method of calculating the water balance of Thorthwaite Mather , while the method of calculating the nature of rain using the method of classification of rain properties with normal criteria (85% - 115%), below normal (<85%) and above normal (> 115%) then presented in graphic. This condition shows that El Nino has a big influence on availability of soil mosture in Bima, West Nusa Tenggara. The most deficit of soil mosture occured in August.
