Starting rides around sunset when it is 110F is great as the low to no sun makes a huge difference and it only gets cooler as the rides goes on. Starting at 100F in the morning for a long ride is a poor idea.

I too cycle to work for the past 17 years and typically leave work for home at 4pm for a 12mi commute. Under 108F is great. Over 115F is where it one really starts to cook. I've had several rides home 118-120F which would likely be impossible if I had not acclimated through the spring.
