The short answer
A professional installation is governed by the adhesive, primer, glass and vehicle procedures—not by a single internet temperature number. Phoenix heat can make the glass and body much hotter than the reported air temperature, while low humidity and direct sun can change product behavior. Rain can contaminate a prepared bonding surface, and strong wind can introduce dust or make large glass unsafe to handle. The current AGRSS standard requires the retention system to be used within the manufacturer's specified conditions.
A technician may create shade, cool the vehicle gradually, use a protected work area or reschedule the job when conditions cannot be controlled. The glass, pinchweld and products should not be treated as ready merely because the truck arrived. Ask how the installer measures or manages conditions and whether the selected adhesive's safe-drive-away calculation accounts for temperature, humidity and airbags. If weather changes during the appointment, allow the technician to pause or move the work. A delayed or relocated installation is preferable to moisture, debris or temperatures compromising preparation, bonding, calibration or safe handling.
