Now, our nights cool off into the 60s or 70s F / 17-26C. When the real heat hits, in July, nights are almost always over 80 F / 26.5C. Nights can reach 90-95 F / 32-35C or higher at times. We can't grow (outside) most plants in the Crassula family, nor Tillandsias, because of the hot nights. Many cacti need to be treated here as summer-dormant. They mostly grow late winter until nights get hot, and again in fall until days get cool. Cacti love hot days and cool nights, since they have crassulacean acid metabolism.
Nights here begin cooling down again in mid October. Halloween is too hot during the day for regular costumes, and too cold during the night for skimpy costumes (antifreeze beverages help.)
