Roatan doesn’t have a dry season and the tropical weather of the Caribbean allows for the occasional thunderstorm. Off shore trade-winds, rain, and overcast are all part of the tropical landscape. However, no need to worry, just as fast as the clouds roll in, that’s how fast the sunshine can reappear.

Humidity on Roatan

The tropical climate brings above average humidity levels to the Bay Islands and is part of life in the Caribbean. Roatan Island experiences mildly humid to very humid conditions reaching in the upper 90’s. Somewhat the same relative humidity as people living in the southern United States, Canada, and parts of Europe. The dew point (muggy) is a better indicator on how comfortable a person is and how they perspire when exposed to this type of climate. Thus, the beginning of the year to mid year is more tolerable for most, both in relative humidity and dew point.


Roatan Weather Expectations

All the data and weather projections can’t guarantee the weather as we would like. Sure, we can have a relative understanding of what the weather may be, but never depend on it. For example, the rainy season is September through January, but there are times when Roatan receives little rainfall during that time period. The traveler prefers clear skies and sunshine for the limited time they have on the island. I mean, you probably left the frigid weather up north for fun in the sun. For the most part, Roatan weather is sure to please, just let Mother Nature do her job and you will have memorable times from your visit to the western Caribbean.
