July through October and it is well into monsoon season in Bangladesh, where it gets cool and wet. Very wet. These months see about 80 percent of the nation's rainfall, causing intense flooding across the country. Most parts of the country receive at least 2,300 mm of rainfall per year. Due to its location just south of the foothills of the Himalayas, where monsoon winds turn west and northwest, the region of Sylhet in northeastern Bangladesh receives the greatest average precipitation. The western region of Rajshahi is a rare relatively dry area, which proves useful for visiting the numerous archeological sites here, particularly Puthia city and its notable Hindu temples and palaces built by zamindar aristocrats.
