What type of information does a METAR report provide?

A METAR report is a standard format for reporting current weather conditions at an airport, and it specifically provides routine weather observations. This includes data such as temperature, dew point, wind direction and speed, visibility, precipitation, cloud cover, and significant weather phenomena.

The primary purpose of a METAR is to give pilots and air traffic controllers up-to-date information about the weather conditions they will encounter during flight operations. It is issued at regular intervals (usually every hour) and is crucial for safety and operational planning.

Other options, like forecasts for the next 24 hours, pertain to different types of reports such as TAFs (Terminal Aerodrome Forecasts) which provide weather predictions rather than actual observations. Air traffic control updates are related to traffic management rather than weather specifics, and flight arrival and departure schedules are logistical details that do not pertain to weather conditions at all. Thus, the METAR's focus on current weather conditions makes it a vital tool for aviation.
