Nine days in Texas in August without water would kill just about anything tropical.
I am bringing them inside to my living room, which is very bright with lots of morning sun. AC and ceiling fan will be on to keep the air movement, but I am more likely set it to 85 degree to save the energy.

BTW, Houston reached 100 yesterday. Luckily for orchids, we also have higher humidity. So far, orchids are doing well outside.
