Your Temperature Timeline

  • A normal temperature is between 36 and 36.8ºC (96.8 and 98.24ºF).

    In children, any temperature of 38°C (100.4°F) or above is considered high.

    A high temperature can be caused by a number of things and usually indicates that you have an infection of some kind, including common illnesses like a cold or flu.

    However, a high temperature can also be due to other infections, some of them serious, so it is important to look at other symptoms you might have at the time.  Most temperatures clear up within three days.

    Choose from the options on the right to see what you should do when you or your child has a high temperature.
