Like much of Kerala, Alleppey has tropical weather. As such, it is humid throughout the year. The best time to visit Alleppey is between the months of August and February - with cool weather and relatively lower humidity. Numerous festivals are celebrated during these months including the Snake Boat Races. If your plan includes spending significant time on a boat in the backwaters, Alleppey is fun to travel to through May. June and July are the peak monsoon months
