The present study investigated the climatic vulnerability of the peanut cropping system in Gujarat's Junagadh district. The Junagadh district is situated in western Gujarat between the latitudes of 70.150 and 70.550 and the longitudes of 20.470 and 21.450. One of the significant oil seed crops in India is the groundnut crop. Gujarat is India's top groundnut producer. Gujarat's Junagadh district produces the majority of the state's ground net crops. Planning for climate change mitigation efforts requires an understanding of the past, present, and projected temperatures and precipitation in the Junagadh district. IMD provided historical daily temperature data with a resolution of 100 km for the years 1951 to 2019.Historical daily temperature data from 1951 to 2019 is downscaled to 1 km from IMD at a resolution of 100 km x 100 km. Data on historical precipitation was downscale from Cru's 25 km x 25 km resolution to 10 km. The temperature projections (RCP 4.5 and RCP 8.5) for five South Asian codex domain models at resolutions of 50 km x 50 km and scaled down to 1 km are displayed. 50 km x 50km and 10km downscale daily data from five South Asian codex domain models. The Taylor diagram demonstrated that, when tested against cru data, all models perform better in terms of rainfall and temperature. The cm5a model outperformed the other models in terms of performance. Maximum temperatures are seen to rise from 32.760 C to 35.50 C (RCP 4.5) and 37.20 C (RCP 8.5) and minimum temperatures are seen to rise from 23.920 C to 25.300 C (RCP 4.5) and 27.480 C between 1970 and 2100 (RCP 8.5). June, a crucial month for the germination stage of groundnut crops, sees an increase in both the maximum and minimum temperatures. From 1970 to 2100, June to November total precipitation increased from 853.2 mm to 1029 (RCP 4.5) and 1097 mm, respectively (RCP 8.5).
