The lowlands including Panama City average 80F-90F degrees during the day, and the highlands have spring-like temperatures year-round. Dry season is from midd-December through May and green season from May through Dec. (typically a shower in late afternoon).
The Panama Canal rainforests are among the most accessible nature-rich rainforests in the world. Over 50,000 acres of pristine rainforest hosts 105 species of mammals, 525 species of birds and 124 species of reptiles and amphibians. A nature-rich area so close to the metropolitan capital is a feature unique to Panama. The Panama Canal, just 30 minutes away from Panama City, requires a vast rainforest watershed to feed water to its lock system which uses millions of gallons each day. For this reason the Canal Zone has had to actively preserve its circumvent natural resources, making for plentiful green areas.
