While its average annual rainfall cannot compete with Atlanta’s, it has more rainy days. On average, Seattle gets 152 days of rain each year.

For a day to be considered rainy enough to count, it must get a minimum of 0.01 inches. This is usually rain, but it can also be melted ice or snow that falls from the sky.

Seattle generally gets a mild amount of precipitation accumulating on the ground.

As this city is prone to frequent rain, it is no surprise that Seattle has more cloud cover than any other United States city.

But is Seattle the rainiest city? If you mean the number of days it rains, then yes. But for total rainfall, Atlanta comes out on top.

Tip: Be ready for rain every day in Seattle. There is a good chance you will get wet if you are out without an umbrella!

Spring in Seattle isn’t as rainy as the winter, and you notice things getting dryer as the summer approaches.

However, it’s still Seattle, so you should still be ready for a little bit of drizzle.

Why Does It Rain So Often in Seattle?

It’s the fact that Seattle is so close to the Pacific Ocean that causes frequent rain.

The enormous amounts of moisture that the ocean emits into the air hang there as vapor.

This will travel overland. When it gets to the Olympic Mountains and Seattle, it turns into rain.

The vapor has to get over the Olympic Mountains before it gets to Seattle. This helps to cut down on how much rain the city would get otherwise.

The vapor starts forming into rain when it meets the air over the mountains.
