Hot air balloons fly when the weather is relatively calm and when there is no turbulence. Opposite to a glider, hot air balloons fly when the sun is low over the horizon and this is because hot air balloons avoid thermals of flying in thermic conditions. The best weather for ballooning normally happens either in the early morning or in the evening when the sun goes down.

The simple answer is to dress for an outdoor activity. Be PRACTICAL in every sense. Ballooning tends to be a hands-on experience and you can get a little dirty on different tasks, especially on helping to pack the balloon away after the flight. Avoid expensive clothes and whites if possible. Above everything else, be practical with what you wear on your feet.
