Alappuzha has a wonderful past that owes its modern existence to the efforts of Diwan Raja Kesavadas in the second half of the 18th century. Diwan Raja Kasavadas was instrumental in making Alappuzha a major port city in his time and for developing the system of inland canals, used for transportation and navigation, that is seen today. The name Alappuzha means "the land between the sea and network of rivers flowing into it". It is a fitting name: there are a significant number of canals, backwaters, beaches and lagoons in and around the city. Alappuzha, and Kerala in general, has excellent weather due to its proximity to the ocean. The temperature rarely goes above 35 °C and never below 20 °C. The best time to visit is from September to March. The monsoon, from June to August, always brings heavy wind and rains. This is an excellent time to visit if you want to partake in a bit of monsoon tourism.
