A high temperature for a 3-year-old is generally considered to be 100.4°F (38°C) or higher when measured with a rectal thermometer. For oral or axillary (underarm) measurements, a fever can be defined as 100°F (37.8°C) or higher. If a child has a high fever accompanied by other concerning symptoms, it's important to consult a healthcare professional.
