Climate change is one of the global environmental issues that has gained increasing attention in recent decades. The rising concentration of greenhouse gases in the atmosphere has led to alterations in the Earth’s climate system, characterized by an increase in global air temperatures, changes in rainfall patterns, and a higher frequency of extreme weather events. This study aims to analyze trends in rainfall and extreme air temperature as indicators for detecting climate change in Banjarbaru City. The data used consist of long-term climatological records from 1995 to 2024 obtained from the BMKG Meteorological Station Syamsudin Noor Banjarmasin. The results indicate an increasing trend in both rainfall and air temperature in Banjarbaru City during the observation period, suggesting the occurrence of climate change. The Oldeman agroclimatic classification shows that Banjarbaru City has consistently exhibited a C2 climate type over the past 30 years. However, there has been an increase in the number of wet months, from 5 months in the first decade to 6 months in both the second and third decades.
