Early mornings offer the best conditions for hot-air balloon flying, since the air is cold and stable. During the warmer part of the day, the sun heats the air above which causes thermal activity and more unstable air, meaning unstable flying. However, in the mornings, the coldest part of the day, the hot-air balloon inflates and launches easily, while stable air offers much calmer flying. Besides, watching the sunrise from way up high is especially beautiful.
