Climate & Weather Guide in Guyana

Climate zones, seasonal temperatures, rainfall patterns, and best travel times

Guyana has a hot, humid tropical climate with little temperature variation through the year, and the country is dominated by Köppen tropical types, mainly rainforest and tropical monsoon climates along with a drier savanna belt in the south and southwest. Coastal areas are wetter and experience two rainy seasons, while inland and southern areas have a stronger wet-dry pattern and slightly more heat stress from lower elevation and more open terrain. For residents and expats, the main practical issues are persistent humidity, frequent heavy rain, and occasional flooding in low-lying areas, especially near the coast.

Regional Climate Variations

Coastal Plain

The coastal plain, where most people live and where Georgetown is located, is hot, humid, and very wet by tropical standards. Rainfall is abundant, with annual totals often above 2,000 mm and two rainy seasons linked to the seasonal movement of the ITCZ. Temperatures stay fairly steady through the year, with warm days and only slightly cooler nights, but the high humidity can make it feel warmer than the thermometer suggests. This is the most practical zone for services and urban life, though drainage and flood management matter.

Summer:27-30°C

Winter:25-28°C

Very high rainfall

Steamy, lush, and seasonally very wet, with frequent showers and a strong tropical feel year-round.

Interior Rainforest Belt

The interior rainforest belt covers much of central Guyana and is among the wettest and most consistently humid parts of the country. Climate conditions are broadly tropical rainforest, with heavy rainfall, dense forest cover, and only modest seasonal temperature change. Rain is common in much of the year, and travel can be affected by muddy roads and river conditions. For residents, the environment is green and ecologically rich, but daily life is shaped by moisture, insects, and limited infrastructure outside major settlements.

Summer:26-29°C

Winter:24-27°C

Very high rainfall

Deeply tropical, persistently humid, and green almost everywhere, with frequent rain and limited dry comfort.

Southern Savannahs and Rupununi

The southern savannahs, including the Rupununi, are drier than the coast and the forested interior and are commonly described as a tropical wet-dry or savanna climate zone. This region has a longer dry season, more open landscapes, and slightly larger temperature swings than coastal Guyana. Annual rainfall is lower than in the north, and the climate can feel hotter in exposed areas because of stronger sun and less canopy cover. It is the most seasonally distinct part of the country and often appeals to residents who prefer a less continuously wet environment.

Summer:28-32°C

Winter:24-27°C

High rainfall

Hotter, sunnier, and more seasonal than the coast, with a clearer wet-dry rhythm and wide open landscapes.

Guyana is a mostly tropical country with limited temperature variation, but strong contrasts in rainfall between the wet coastal belt, the very wet interior forests, and the drier southern savannahs. It can suit expats who are comfortable with heat, humidity, and heavy seasonal rain, especially if they value green surroundings and a slower tropical pace of life.
