Today was colder, around 91 F (33ºC)...
The min was 65 F (18,5 ºC). This value was recorded at 07:00 which means most of the night it was over 68 F (20ºC).

As much as I like the cooler weather it does mean summer is over, so sad.
Not really...while tomorrow the forecast gives temps of 81 F (27ºC), then it starts to rise again to the 99 F (37ºC).
Persistent cooler days (77 F / 25ºC) start usually by late September, beginning of October.
20C is a reasonable night temperature for succulents (including most orchids) having to endure high day temperatures. I think if the sun or wind does not burn your leave, the plants will recover.
