We visited this Manzanillo in December and you
would have overheated if you didn't have shorts and a T-shirt on. The
days were partly cloudy, warm, and quite humid. Temperatures during the
daytime were hovering in the 80's. One word of caution is that it is
very easy to get sun burnt even if you are not exposed to the sun for
very long. It is especially easy for sun starved tourists who are
vacationing from much colder climates to lay out in the sun for several
hours. June through September tends to be extremely
humid and rainy.
