Cloud Base Calculator

How to Calculate Cloud Base

Calculating cloud base can be done with the following variables:

• Temperature


• Dew point temperature


• Current elevation

Then you can use these values in the cloud base formula to get your answer. The formula is: Where:

• CB = Cloud base elevation


• T = Current temperature


• DP = Dew point


• LR = Lapse rate (4.4)


• E = Current elevation

Don't Know the Dew Point?

You can use our Dew Point Calculator to find this value!

Understanding Your Results

When you use this calculator you will get two different results with your answer. The cloud base, which is the lowest elevation at which the clouds will be at, as well as the temperature of those clouds. You can alter the units of measurements for these answers to get a better understanding of them as well.

How to Use the Cloud Base Tool

Our cloud base calculator tool is designed to be very easy to use and efficient as well. You can follow these steps to use the tool:

1. Enter the current temperature. Change the unit of temperature if needed.


2. Enter the current dew point. Change the unit of measurement if needed.


3. Enter the current elevation. Change the unit of measurement if needed.


4. Hit the calculate button and get your answer instantly.

Example Calculation

Let's say we are going to be doing a project and with this project we need to find the cloud base. We can use this tool to help us do that. Our current situation is as such: a temperature of 70 degrees Fahrenheit, a dew point of 60 degrees Fahrenheit, and a current elevation of 1,240 feet. We can enter these values into their corresponding fields and then hit calculate. When we do we learn that the cloud base is at about 3,512 feet and the clouds have a temperature of about 57.73 degrees Fahrenheit.
