Little help please. Can plants become sterile if Temps are HIGH

[GardenRookie]

Forgive if this shows up twice. I posted it and don't see it anywhere.... I started seeds indoor on April 9th. I moved them outdoors under a hoop house that’s about 3x3x5ft. On days in the 60s the inside thermometer reads 120degrees! The plants look GREAT for being a month along. I keep them watered because the potting soil drys out quickly. The thermometer sits on the grass and I am sure it affects its reading. So my questions are... Is this to hot? and Will such temps cause the plants to some how be sterile once planted outdoors? Thanks for the help.
