Slightly overheating when driving but temp fluctuates back to normal. Does the thermostat need replacing

I can start the car and let it idle for 30 minutes and the temp never goes above normal. When I drive it the temp sometimes goes a little above half way to almost 3/4 then goes back down. It hasn't overheated yet. Do you think this could be a thermostat issue
