I'm in WV for location context. My pool build started July 3rd and I'm currently sitting with a gunite shell and no plaster. From what I've read about the application:
All materials and effected areas should remain above 50°F / 10°C (fifty degrees Fahrenheit / ten degrees Celsius) or below 100°F / 38°C (100 degrees Fahrenheit / 38 degrees Celsius) 24-hours prior and 72-hours after placement.
