TEMPO on a TAF indicates what?

TEMPO on a TAF indicates what?

• A. Indicates a permanent change in conditions
• B. Indicates a 5 minute variation
• C. Indicates temporary variations from prevailing conditions lasting 30 minutes or more but less than 60 minutes
• D. Indicates a forecast covering the next 24 hours

Answer: (C)

The main idea here is that TEMPO signals temporary fluctuations from the prevailing forecast conditions. In a TAF, the weather is described as what is expected most of the time, but TEMPO indicates short-lived changes that will occur only for a period within the forecast window and then revert back. Those temporary variations are typically lasting 30 minutes or more but less than 60 minutes, which is why this option best fits. It’s not showing a permanent change, a fixed 5-minute blip, or a forecast covering the entire 24-hour period.
