There are plenty of temperature swings in the tropics. There is a
reason that the rain forests are covered by fog in the mornings. A
google image search for "rain forest fog" yeilds more images than you
can view in a day.
There is no magical 20 degree number to have condensation. If the
overall humidity is high, a couple of degrees difference is all that is
required. If the relative humidity in the warm sunny areas is 95%, you
can be assured that the shady areas will have condensation everywhere,
especially on thermal masses.

get condensation with sufficient temp swing. Working from memory, I
think it's ~20 degrees. Someone will need to confirm.
