Nicaragua has distinct dry and rainy seasons, and this in turn varies from coast to coast. With the possible exception of the last month of the dry season (usually mid-April to mid May) when soil is dry and dusty air, there’s really no bad time to visit Nicaragua. However, the most pleasant time to visit the Pacific or central regions of Nicaragua is when you start the dry season (December and January), when temperatures are cooler and the foliage is lush.

The dry season is from November to April and this is the best time for hiking, camping and going out at night, as it coincides with the peak tourist season (December to March), the peak is more pronounced along the border with Costa Rica. When summer is ending Nicaragua Pacific forests lose their leaves and lake levels drop revealing beautiful sandy beaches on the coast of the lake. This lake is given to good use as temperatures remain very warm.
Then there are the mountains with their forests of cold mist above each volcano. All with monolithic granite peaks of the central highlands, where the seasons are confused in the fog in the morning cold, with temperatures between 12 ° C (54 ° F) and 24 ° C (75 ° F).
