This cloud base reference table shows the cloud base height for a range of surface temperature values, assuming a dew point of 15 °C. Every figure is computed with the same engine that powers our Cloud Base Calculator, so the numbers are exact.

How to use this table
Find the row closest to your surface temperature and read across to the cloud base height. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Cloud Base Calculator for a precise answer.
