Best Time to Visit Georgetown: Dry Seasons, Trade Winds and Mashramani

Positioned less than seven degrees north of the Equator along the Atlantic Ocean, Georgetown has a warm equatorial rainforest climate (Köppen Af) tempered year-round by steady northeast Atlantic trade winds (the sea breeze). According to official World Meteorological Organization (WMO) and Hydrometeorological Service normals recorded at the Georgetown Botanical Gardens (Station 81001), daytime temperatures barely fluctuate across the calendar, ranging from 28.8°C in January to 31.8°C in October, while nights stay between 23.3°C and 24.7°C. Instead of summer and winter, travel planning revolves around two dry seasons and two wet seasons created by the annual migration of the Intertropical Convergence Zone.

August to November: The Long Dry Season (Driest and Sunniest Skies)

The longest and most reliable dry window in Georgetown runs from mid-August through November. September and October are the driest months of the entire year, averaging just 9 rain days per month (97.5 millimetres in September and 107.2 millimetres in October) alongside the highest daily sunshine totals and warm afternoon highs of 31.5°C to 31.8°C.

This is the prime season if you plan to combine your time in Georgetown with interior flights from Ogle to the Rupununi Savannah, giant river otter spotting on the Essequibo and Rupununi rivers, and clear-sky morning flights to Kaieteur Falls.

February to April: The Short Dry Season, Peak Waterfall Flow, and Mashramani

The second ideal window is the shorter dry season from February through April, when monthly rainfall drops to 88.5 millimetres in February (10 rain days) and 111.0 millimetres in March (10 rain days) with comfortable daytime highs of 29.2°C to 30.1°C. Visiting in February or March gives you dry walking conditions around Georgetown's wooden landmarks while the Potaro River still carries powerful water volume over the brink of Kaieteur Falls following the December and January rains.

May to July and December to January: The Two Rainy Seasons

Georgetown's primary wet season runs from May to July, peaking in June (327.7 millimetres across 23 rain days), while a secondary wet season arrives from December to mid-January (261.9 millimetres in December across 18 rain days). Even during the wet months, rain often falls in intense tropical downpours interspersed with bright spells, and the giant Victoria amazonica water lilies in the Botanical Gardens are at their lushest.
