Rain often occurs when the relative humidity is below 100 percent (but it is always 100 percent in the clouds where condensation is occurring.)
Is humidity 100 when its raining?
Most of the time when it is raining the relative humidity is 90-99 percent, but not often is it 100 percent . ... Condensation and raindrop formation occur within clouds where the air is saturated and the relative humidity is, indeed, 100 percent.
Does 100% humidity mean rain?
So 100 percent humidity might not mean rain , but it does mean dew. 2. ... Dew occurs when the relative humidity reaches 100 percent. “Dew point temperature is an absolute measure of the amount of water vapor in the air,” Sobel said.
Why is humidity not 100% when its raining?
So it doesn’t have to be 100% when it’s raining after all. The reason has to do with evaporation and condensation . When a surface of water (which could be a raindrop) is in contact with open space (which could be filled with air or some other gas or a vacuum), water molecules will be going both ways.
What does 100 humidity feel like?
A relative humidity of 0% would make it feel like it’s only 69° F (20.5° C). On the other hand, a relative humidity of 100% would make it feel like it’s 80° F (26.6° C) . So what’s a comfortable humidity level? Studies have shown that we tend to feel most comfortable at a relative humidity of around 45%.
