Is it warm in there?

Yes

It's worth the heat and humidity in the butterfly habitat...compared to the outside Ariz. Temp, 105° f.

Humid and warm

Butterflies are from tropical areas. The conservatory maintains a climate they like (80 degrees and 80% humidity).

I agree. The butterfly area is warm amd humid. But the area where the fish and reptiles are, is nice and cool.

I second Anthony's response.

Yes, it is warm and humid but not overly uncomfortable.. shorts/t-shirt are appropriate

The atrium where the butterflies fly around in is warm with humidity, but you can come in and out as many times as you'd like, also water is acceptable to bring in just no food or sugary drinks
