Ruby Balloon Floating over Norfolk
  

Weather

The InsideThe basic meteorological requirement for a balloon flight is calm winds of 15 knots / 17mph or less, good visibility and stable atmosphere with no thermals, rain or thunder activity. Personally I think over 9 knots / 10mph is a bit fast and will involve a long drag on landing.

These conditions are most frequently be found early in the morning and the last few hours of daylight in the evening, which is when most balloon flights take place.

Ballooning is an all year round sport - in the summer months the long hours of daylight and generally better weather favour more flying; during the winter months the opportunities for flying tends to be only during working hours so for private balloonists they can only fly on weekends unless they take a holiday.
