Winds of 5-10 mph are ideal for takeoff and landing. Once in the air the balloon can travel at much faster speeds. Balloons can only be flown in VFR (Visual Fight Rules). These are conditions where you can see at least 10 miles. It is important to look at weather conditions up to 200 miles away. That weather may impact the flight. Typically balloon flights take place at sunup and a few hours before sundown because the winds are usually the calmest.
