Our pilots look at more than one weather forecast model and use personal observations and consider all the factors when basing the decision to fly on stay on the ground. Wind speeds, precipitation, barometric pressure, and fog or low clouds are all issues that may require us to cancel and reschedule your flight. Our regulations state that we cannot fly if the clouds are below 3,000 feet or in fog. Occasionally the wind may be calm on the ground, but too strong at higher altitudes at which we would be flying. The best flying conditions include surface winds and to the top of the balloon be below 9 mph, and winds up to 1,500 feet above the surface be at or below 19 mph. Your safety and that of the rest of the passengers and our pilots is our primary focus. The pilot always reserves the right to cancel if weather conditions are favorable. We will call you the day before your flight to give you our latest weather update and let you know if conditions are predicted to be within our safety guidelines.
