Why is there no humidity in California?
California doesn’t get humid. There isn’t enough vegetation except in the Central Valley, but because of the coastal onshore flow the humidity is swept away. And again occasionally there is a monsoon effect that comes up from Mexico.
Why is the West Coast drier than the east coast?
There are spots on the western USA as wet or wetter than any eastern USA Locations. The region is generally drier because of very high mountains. They sweep the water out of the air and downslope winds are very dry.
Why are West coasts drier?
In the Northern Hemisphere summer, high pressure in the Pacific Ocean builds toward the California coast, resulting in a northwesterly airflow, creating the cool, dry, and stable weather conditions prevalent along the West Coast in summer.
Why is it less humid by the ocean?
Heat is needed to evaporate water, changing it into vapor in the air. This heat is called latent heat. On the interior of continents, where the air is further from oceans and less able to pick up vapor from the sea surface, there is generally lower humidity than places that are near the ocean.
What state has the worst humidity?

What US state has the least humidity?
Nevada
1. Nevada. Unsurprisingly, the first entry on this list is a state famous for its arid climate and desert-like environment. With average relative humidity sitting at 38.3%, Nevada has the lowest relative humidity (when comparing states) in the country.

Why is California warmer than the East Coast?
Land has a lower heat capacity than oceans, and it also heats and cools faster than oceans. During the winter, land is much colder than the oceans. When the westerly winds blow over it, the air cools substantially. Thus, the East Coast experiences extreme cold weather during the winter.
Why is West Coast so hot?
The heat comes from a high pressure system over the West, a buckle in the jet stream winds that move across the U.S. and vast swaths of soil sucked dry by a historic drought, said Marvin Percha, a senior meteorologist for the agency in Phoenix.
Why is there low humidity on the west coast?
“Back home” is Cape Cod, E Coast USA. The West coast has low humidity because of the cold northern current running just offshore. The warmish air from the interior of the Pacific Ocean flows eastward over the narrow strip of cold water flowing south along the west coast, cooling the air and precipitating the excess moisture out in the form of fog.
Why is the eastern US more humid than the west?
The east coast has tropical humid air moving up from the gulf of Mexico during the summer combined with all the moisture transpired from the broadleaved deciduous trees during the summer. The humidity here in SC really climbs in spring once the deciduous trees have leaved out in the spring. I like…
Why are the waters on the west coast cooler than the east coast?
9 Answer s. The waters off the west coast tend to be cooler than those on the east coast (especially in the Northern Hemisphere summer). Winds blowing over water will reach a temperature close to the water temp. The air near the surface of the water is close to saturated. The dew point temperature refers to the temperature you’d have to lower…
Why is the dew point lower on the west coast than the east coast?
@elijahsuicide: the dew point is a function of the temperature, not of geography. The waters off the west coast tend to be cooler than those on the east coast (especially in the Northern Hemisphere summer). Winds blowing over water will reach a temperature close to the water temp. The air near the surface of the water is close to saturated.
