4 - The ideal wind speed for hot air balloon flights - To provide the best conditions for a safe balloon flight landing the maximum surface wind speed on the day of the balloon ride must not exceed 10 miles an hour.
Average surface wind speeds for all months range between 6 and 10 miles per hour. Upper air winds (more than 1500 meters above mean sea level) are usually southwest to northwest in winter and spring, south to southwest in summer, and southwest to west in autumn.
