In this study, 3-hourly rainfall data of 10 years (2008-2017) were analyzed to have a clear insight of rainfall variation between day and night around the Patenga coastal area of Bangladesh. Both descriptive and inferential analysis was conducted to examine the variation between day and night, to detect the time when rainfall is minimum and maximum, and ARIMA model, which stands for Auto-Regressive Integrated Moving Average, was applied to predict the highest and the lowest future trend of rainfall. The study revealed that midnight rainfall dominated the study area with a maximum rain at late night, precisely 3 AM. Contrary to this, comparatively lower rainfall was observed at day-time with the least rain around 3 PM. However, trend analysis depicted a significant downward trend of rainfall midnight, though it was one of the most maximum rainfall hours. Moreover, the ARIMA model predicted a 3 AM and 3 PM forecast for 2018-2027, where +11.85 mm rainfall per year for 3 AM and +0.52 mm per year for 3 PM were predicted.
