Weather in December

December in Guyana sees the continuation of the minor rainy season that began in November, but with a gradual decrease in rainfall as the month progresses. The beginning of December often experiences precipitation levels similar to those of November, exceeding 200mm (7.87"). However, by the end of the month, these levels taper off, indicating the close of the minor rainy season and the transition to drier weather.

Major cities like Georgetown, New Amsterdam, and Linden, along with smaller communities, experience this decline in rainfall. Despite the lessening precipitation, December's climate remains characteristically warm, in line with Guyana's tropical monsoon weather. Average temperatures in December range from 23°C (73.4°F) to 30°C (86°F), sustaining a comfortable warmth that is consistent throughout the year.

As December transitions into January, the decrease in rainfall becomes more pronounced, heralding the onset of a dry period that marks the start of the new year. Thus, while December is part of the minor rainy season, it also represents a transitional phase leading to the drier months of the upcoming year. Consequently, the weather pattern in December offers a blend of the wet conditions of the minor rainy season and the drier conditions that characterize the beginning of the new year.
