The ambient temps in my snake room vary enough seasonally to simulate the slight seasonal changes in equatorial western africa. I don't mess with the belly heat. However, I just realized the wet season in S. Florida coincides with the hot season, while in Africa it coincides with the cool season. This may be why dry winters here can be troublesome. Usually though, we get just enough rain and coinciding pressure change to get things going.
