Georgetown sits just 6 degrees north of the equator and maintains a consistently hot, humid tropical climate year-round with little temperature variation.
The city experiences two wet seasons and two dry seasons annually, with the heaviest rains from May through July and a secondary wet period from November to January making waterproof gear essential for most of the year.
Temperatures hover persistently between 24°C and 31°C throughout the year, with night-time offering minimal relief from the daytime heat.
Humidity levels regularly exceed 80% and the coastal trade winds, while present, do frustratingly little to offset the oppressive moisture in the air.
Fabrics that claim to be quick-drying become your most valued possessions as the combination of sudden downpours and relentless humidity means nothing ever truly dries completely.
Georgetown doesn't observe spring, summer, autumn, or winter—instead the calendar alternates between periods of merely hot and humid versus hot, humid, and perpetually wet.
