The sun is probably still making it into your room just enough to influence your waking in the morning. I believe the sun has a stimulating effect on certain neurotransmitters in the brain. It's effects are pretty powerful and does not take much to notice a difference. I have experienced the same sensitivity to the sun in the morning. I too have had my blinds blocking most of the sunlight but would still notice I was waking up easier on sunny days.
