When are initial wind readings taken before a drop?

Initial wind readings are taken 1 hour prior to drop time to ensure that the information provided to jumpers is as accurate and relevant as possible. This time frame allows jumpmasters to assess the wind conditions that the jumpers will encounter during their descent. Wind conditions can significantly affect the trajectory and landing accuracy of parachutists, so having current data helps in making informed decisions about the drop zone and overall safety.

Taking wind readings at this interval also accounts for any potential changes in weather patterns or atmospheric conditions that could occur closer to the drop time. It strikes a balance between being timely enough to provide relevant information while also being far enough in advance to make necessary adjustments to the drop plan if needed. Options suggesting shorter or longer time frames would not provide the same balance of accuracy and preparation time.
