Your personal rhythm within a 24-hour period, as well as your relationship to the sun and moon, heat and cold, and the crispness or thickness of the changing seasons, can indeed factor into which asanas you practice when. Some people are raring to go first thing in the morning, while other people won't even speak for at least an hour after the alarm goes off. Some love winter and outdoor activities such as skiing and snowboarding. Others put on a few pounds and hibernate in the winter and come alive with the fire energy of July and August. Since an important part of yoga practice is getting to know yourself and how you change from moment to moment, it makes sense to let your energy inform you about how to practice according to the season or time of day.
