UK Cloud Base Calculator
Calculate estimated cloud base from temperature and dew point
using the standard 400 ft per °C rule. A useful tool for UK PPL(A)
students studying for the Meteorology exam.
Free Tool
This calculator uses the standard lapse rate formula: for every 1°C spread between the temperature and the dew point, the cloud base is approximately 400 feet above the ground.
This is a vital tool for the UK CAA Meteorology theory. Although this tool can prove useful in pre-flight planning, it must not be relied upon as an accurate pre-flight briefing tool.
