Suriname, positioned in the northern part of South America, sits on the Atlantic coast, bordering Brazil, Guyana, and French Guiana. Its terrain is a blend of coastal lowlands, rolling hills, and rainforests. The country boasts an "Af" Köppen climate classification, which implies a tropical rainforest climate. This classification indicates that Suriname experiences no temperature below 18°C (64.4°F) throughout the year. In addition, every month sees a significant level of rainfall, making Suriname one of the world's wettest countries. Generally, temperatures are consistently high, ranging between 26°C (78.8°F) and 32°C (89.6°F).

The optimal time to visit Suriname is during the short dry season, from February to April, or the long dry season, which stretches from August to November.
