Aedes aegypti is the primary vector of Dengue Fever (DBD), and its development is strongly influenced by temperature and humidity. This study analyzes climatic suitability for vector development by comparing microclimate data from Makassar City with macroclimate data from Sidenreng Rappang (Sidrap) Regency. The Makassar microclimate data were recorded using an IoT system equipped with a DHT22–ESP32 sensor at the Zoonotic Laboratory, Faculty of Medicine, Hasanuddin University, over a seven-day period. Meanwhile, the Sidrap macroclimate data were obtained from NASA-POWER reanalysis for the period 2000–2024. All data were normalized using the Min–Max method and analyzed with Euclidean Distance to assess the similarity of temperature and humidity patterns to biological reference thresholds.The results reveal distinct climatic characteristics between the two locations. Makassar exhibits more stable temperature and humidity conditions (27–29°C; 62–72%), whereas Sidrap shows greater fluctuations (21–35°C; 73–86%). The combined Euclidean Distance values in Makassar range from 0.64 to 1.06, while Sidrap ranges from 0.87 to 0.98. Both locations demonstrate the highest climatic suitability during the July–September period, characterized by stable temperature–humidity conditions and close alignment with the optimal biological thresholds of Aedes aegypti. This study highlights that integrating IoT-based measurements with reanalysis data is effective for mapping climatic suitability for dengue vectors. It also emphasizes significant differences in climatic stability and variability between Makassar’s microclimate and Sidrap’s macroclimate.
