Not true.

There are many epiphytes in the Pacific Northwest rain forest. However most
are lichens, mosses and ferns rather than flowering plants.

Wet climates produce many more species and numbers of epiphytes.

There is one more condition you forgot to mention; it has to be warm
enough.
Few of the higher plants thrive as epiphytes where it consistently goes
much
below freezing. Even in the Pacific Northwest rain forest, there are no
higher
plant epiphytes (that I know of), because they are in Zone 8. The
northernmost
epiphytic orchid in the Western Hemisphere, Epidendrum conopseum, is found
as
far north as South Carolina.
