    I wouldn't worry about it, as long as a) the car isn't losing coolant and b) your needle doesn't go into the red zone and c) you are sure your fans are working

    Modern heat gauges are often not "linear", that is, creeping up fractionally. They will often read in "small jumps".

    Modern engines LIKE to run hot. They are more efficient that way, and high ambient temperature will affect how the gauge registers.

    Also, use of AC will raise engine temperature. Most cars have an additional fan that kicks in when the AC is on. If your car has TWO fans, they should both be running when your AC is on.
