Waking up before lights come on

[fergusaur]

My 6-7 month Hermann’s tortoise has been getting up before his lights come on and I want to know if that’s normal behavior? His morning lights come on at 7:00 am and they turn off at 7:30pm. He usually goes asleep for the day between 12-4 pm since it’s winter at the moment. But lately I’ve been noticing that he’s been awake and laying around his eating area hours before his light comes on. I use to keep his enclosure temperature at 68 degrees at night but as of recent it’s become way colder where I live so I just raised it to 70 just to be extra safe for his health. Is his early activity normal ?

He usually sleeps in a burrow under his hide log, but literally came out and proceeded to sleep in the eating area instead
