🇬🇾Guyana

Guyana lies at 1°10′–8°35′N, a country of ~214,969 km² on the northeastern coast of South America between Venezuela, Suriname, and Brazil; comprises a low coastal plain (much of which lies below sea level and is protected by Dutch-built dykes around Georgetown), a vast inland Pakaraima sandstone plateau dominated by the Tepui escarpments and Roraima country, the broad Rupununi savanna in the southwest, and the dense Amazonian rainforest interior centred on the Essequibo and Mazaruni rivers; produces a tropical monsoon (Am) coastal regime, tropical rainforest (Af) across the interior, and tropical savanna (Aw) on the southwestern Rupununi savanna.

Georgetown averages 26°C year-round with 2,290 mm rainfall in two seasons — long rainy May–Aug and shorter rainy Nov–Jan, with two relatively drier intervals; New Amsterdam similar; Lethem in the Rupununi 27°C with 1,800 mm with a marked single dry season May–Sep when fires can spread; the rainforest interior (Mahdia, Iwokrama) receives 2,500–3,000 mm; relative humidity remains 75–85% year-round. Major climate hazards include the severe January 2005 Georgetown floods (most expensive disaster in Guyana's history, displacing 30,000+, costing US$465M), accelerating sea-level rise threatening the entire below-sea-level coastal plain (where ~90% of population lives), intensifying La Niña-driven heavy rainfall events, severe Rupununi droughts and fires during strong El Niño years, and growing pressure on the dyke system as storm surges intensify.
