hi there,
When to go to Honduras depends on what activities you wan to do. Having said this, the ideal time to travel to Honduras is probably in late winter or early spring: February and March are good times also as the forests are still lush after the rainy season, but the climate is warm and dry.
Regarding temperatures in
Honduras, the Bay Islands are usually around the mid-80s (high 20s in Celsius). Along the north coast, they hover in the 70s and 80s (20s in Celsius).
Further inland, in
San Pedro Sula for example, temperatures above 90 degrees (over 30 degrees Celsius) are not uncommon in the early summer, before the rains come.
The climate is milder in the Honduran mountains. Tegucigalpa is often 10 degrees cooler than San Pedro Sula.
