What are the differences in sun/precipitation levels between Dhaka, Chattogram, Gazipura, Rajshahi, Khulna, 5 more?

The comparison of sun hours (sh) and precipitation levels (prec) across various cities in Bangladesh reveals distinct weather patterns. Chattogram stands out with notably low sun hours and high precipitation during the monsoon months, particularly in July and August, where it experiences over 13 mm of rainfall and less than 1 hour of sunshine. In contrast, cities like Dhaka and Rajshahi maintain relatively higher sun hours during the same months but still suffer from significant rainfall. Overall, it can be concluded that cities on the southeastern coast, like Chattogram, face more extreme weather conditions, while northwestern cities like Rajshahi maintain a more balanced distribution of sunshine and rainfall throughout the year.
