Dengue fever is a health challenge in tropical and subtropical countries. The increase in dengue cases in Indonesia is attributed to urbanization, climate change, increased population mobility, and community behavior. This study aims to describe the climate factors, including temperature, humidity, rainfall, and wind speed, as well as dengue fever cases from 2022 to 2024. This study uses a descriptive observational design with an ecological study approach. The data collection technique used in this study was secondary data in the form of documentation studies by analyzing records of dengue fever case numbers and climate data. The average of temperature are 28.10C (2022), 28.90C (2023), and 29.50C (2024); the average of humidity are 80.3% (2022), 75,2% (2023), and 74.3% (2024); the average of rainfall are 13.7mm (2022), 13.8mm (2023), and 8,2mm (2024); the average of wind speed are 2.1m/s (2022, 2023, and 2024); and the number of DHF are 260 (2022), 541 (2023), and 321 (2024). The monthly temperature ranges from 26.8 to 31.3°C, the average monthly humidity ranges from 65.1 to 85.7%, and rainfall fluctuates significantly, with the highest intensity reaching 28.7 mm. Dengue fever cases show a fluctuating trend, with the highest number in 2023 at 541 cases. Climate factors play a role in the dynamics of dengue cases in Semarang City. Temperature and humidity are within the optimal range that supports mosquito breeding and dengue virus transmission. High rainfall allows for puddles of water to form, which serve as breeding grounds for mosquitoes. Low wind speeds also facilitate mosquito flight activity. © 2025, Universitas Negeri Semarang.
