Can you get heat stroke in 90 degree weather?

A heat index of 90°F or higher calls for extreme caution. High humidity makes it harder for sweat to evaporate from the body. Prolonged exposure to high temperatures increases your risk of heat-related illnesses. When your body can't cool, your body temperature rises and you can develop heat exhaustion or heat stroke.

What temperature is heat stroke?

It occurs when the body can no longer control its temperature: the body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. When heat stroke occurs, the body temperature can rise to 106°F or higher within 10 to 15 minutes.
