Climate Overview
Guyana has a tropical climate with consistently high temperatures (26-34°C/79-93°F) and humidity year-round. Unlike most countries, Guyana has four seasons driven by rainfall rather than temperature — two dry seasons and two rainy seasons. The coast around Georgetown sits below sea level, protected by Dutch-built sea defenses, and flooding risk is real during heavy rains. The interior rainforest and Rupununi Savannah have slightly different timing but broadly follow the same pattern.
