Drought events in a region are strongly related to the surface water availability and low rainfall. Furthermore, drought conditions impact the threat of food security. Bulukumba Regency in South Sulawesi Province is one of the areas that are prone to drought and the risk of crop failure. Therefore it needs anticipatory action to understand the drought index in this region. This study aims to identify the conditions of drought and agitation in the Bulukumba District of South Sulawesi Province. The results of the identification then became the basis for determining the growing season in various types of dryland agriculture cultivation. This study used the Thornthwaite method with a water balance and drought index approach. The sampling method in this study was purposive sampling. Data collection techniques carried out are observation techniques, laboratory analysis techniques, and documentation techniques. Data processing used quantitative techniques and descriptive approaches. The results of the study show that the growing season in dryland agriculture in November, December, and January based on the availability of water in this region. Conversely, the availability of water is very low in May to September and not appropriate to handling the cultivation.
