I always cruise in June due to the fact I have teenagers and school is
out. It has been nice with just an afternoon thunder shower and last
year June 2005 huge down pour late afternoon found out Tropical
storm was approaching but the captain of the Mariner got us ahead of
the storm and we had no problems. I think you might encounter rain
but not enough not to cruise in June. I have a cruise scheduled this
June and no concerns. I will say Cozumel streets did flood and it was a
mess but we still had a great time. Any more questions let me know.
