I have had a beard year round since I was 18 or so.
Here I am at 32 back in 1996 with my middle daughter, this was taken when we lived in Orlando, FL. Never found it to be hot at all...
Here I am at 42 earlier this year in Atlanta at a Cycle World Motorcycle show with the kids. The same daughter 10 years later took this picture.
Here is what 10 years and 3 kids will do to you

Kinda hard to see the beard as it is mostly gray now
