METEOROLOGY – URFACE TEMPERATURE & THERMAL COMFORT CALCULATOR
Dew Point Spread
A precise tool.
What is the Dew Point Spread & How does it work?
The dew point spread is the difference between the dry bulb temperature and the dew point temperature. It provides an indication of the atmospheric moisture content and can be used to estimate the thermal comfort level.
A smaller dew point spread indicates higher humidity, which can make the air feel more uncomfortable due to increased moisture. Conversely, a larger dew point spread suggests lower humidity, leading to greater thermal comfort.

T_db = Dry bulb temperature (°C)
T_d = Dew point temperature (°C)
T_d = Dew point temperature (°C)

Frequently Asked Questions
What is dew point spread?
Dew point spread is the difference between dry bulb temperature and dew point temperature, indicating atmospheric moisture and thermal comfort.
How does a smaller dew point spread affect humidity?
A smaller dew point spread indicates higher humidity, making the air feel more uncomfortable due to increased moisture.
What does a larger dew point spread suggest about humidity?
A larger dew point spread suggests lower humidity, leading to greater thermal comfort.
How is dew point spread calculated?
Dew point spread is calculated by subtracting the dew point temperature from the dry bulb temperature.
Why is dew point spread important in meteorology?
Dew point spread helps estimate atmospheric moisture content and thermal comfort, affecting weather conditions and human comfort levels.
Can dew point spread be used to predict heat stress?
Yes, a smaller dew point spread can indicate higher humidity, which may lead to increased heat stress during hot weather.
What units are typically used for dew point spread?
Dew point spread is usually measured in degrees Celsius or Fahrenheit.
