Wind speed in aviation weather reports is rounded to which interval?

In aviation weather reports, wind speed is standardized to whole knots to maintain consistency and clarity in both communication and interpretation. The use of knots, which is a nautical measurement equivalent to one nautical mile per hour, is essential for pilots and ground personnel, as it directly relates to flight operations, including takeoff, landing, and navigational calculations. By using whole knots, reports remain straightforward and ensure that pilots can quickly and accurately assess wind conditions, which are critical for safe flight operations.

Other intervals, such as whole meters or feet, do not align with the established systems used in aviation, which predominantly adopt nautical terms like knots. Half knots are not typically used in aviation reports, as they would add unnecessary complexity without enhancing the accuracy of wind measurements in practical applications. Therefore, the rounding of wind speed to whole knots is a crucial part of the standardization system in aviation weather reporting.
