The standard forecast period for most Terminal Aerodrome Forecasts (TAFs) is indeed 24 hours. TAFs are specifically designed to provide weather forecasts for aerodromes, helping pilots and aviation authorities make informed decisions regarding flight operations.

This duration helps strike a balance between providing detailed information and the fast-paced changes that can occur in weather patterns.
