Eli5: Why do places with high humidity often have lower relative humidity numbers than places like Southern California?

223 views

For example, I spend time in Little Rock and San Clemente. LR is always far more humid, to the point it’s not even relatable. But SC seems to generally have a higher relative humidity. Right now it is 84% in SC and 54% in LR. Is this because the air in SC somehow cannot hold as much humidity as the air in LR?

In Little Rock, it is now 31C and a relative humidity of 47%. In San Clemente, it is 16C and 84% relative humidity.

The amount of water air can hold depend on the temperate the warmer it is the more water it can hold. The relative humidity is the percentage of max at the current temperature

If you use [https://www.omnicalculator.com/physics/absolute-humidity](https://www.omnicalculator.com/physics/absolute-humidity) you can calculate absolute humidity.

47% at 31C is 15.1g/m^3, 84% at 16C is 11.5g/m^3 so there is more water in the air in Little Rock even if the relative humidity is lower.

If you cool down air the relative humidity increase so 47% at 31C is equal to 100% at 18C. So if you get the moist air into a cold enviorment it will start to condensate to liquid water
