December - April is the best time to visit Central America
The best time visit Central America is during the dry season between the months of December and April. It is also a peak season for tourism in the region when sky is mostly clear and weather is pleasant. A number of national holidays come during this time including New Year, Easter and Christmas.
During the months between December and April, it is dry season almost throughout the region. However, it is also the peak season, so most of the tourist places are crowded and hotels tariffs are mostly high. Weather condition is pleasant during the time and temperatures are slightly lower.
Central America during this time experiences the rainy season when temperature is slightly high and so is the humidity. Many places, especially the coastal region may suffer from hurricane between June and November. It is not really a great time to visit the region but if planning a visit during this time, make sure to carry proper rain gear.
