The climate of Tobago
Perched in the southern Caribbean, Tobago, Trinidad and Tobago falls under a tropical monsoon climate, as classified by the Köppen climate system. This corresponds to the Am code.

The weather in Tobago follows the established pattern of a tropical monsoon climate. As such, the island experiences heavy rainfall during the monsoon, with much drier conditions during other times of the year. January through April record the lowest averages of precipitation, while the period from the end of May till November marks the peak rainfall months, with figures regularly exceeding 160mm (6.3"). A typical year sees rainfall distributed across an average of 14 to 23 days per month.
