Is there one particular "magical" month to go where everything aligns and comes together? Like...consistently great weather, and being able to do the big critters in the north and great stuff in like...ccv?
As Cajun Mentioned,
July is normally a great time but this past year was unseasonably wet. My absolute favorite time in my years on Roatan, except for the christmas party, is late March Early april. Everything is very green from the rains but the rains themselves are going away, By late june a lot is turning brown and if the summer rains forget to fall it is a long summer. Now if your staying in the tourist areas just be careful during those times for Semana Santa as it is the busiest time of the year, prices are higher and accomodations are full
