Have You Noticed It Feels Less Humid Than Usual This June? Here Is How Every State Compares to Average Dew Points From June 1 to June 20

If the air has felt less sticky than normal to you this June across the East Coast or mid-Atlantic, you are not imagining it. New data tracking average dew points from June 1 to June 20, 2026 reveals a fascinating split across the country, with the Southwest and Deep South running unusually humid while pockets of the East Coast and Rocky Mountain West are actually experiencing below average humidity this month.

What Is Driving the Above Average Humidity in the South and Southwest

The states running the most unusually humid this June are not doing so randomly. According to the data, extra heat and moisture is flowing into the Southwest and Deep South from a marine heat wave in the eastern Pacific Ocean. This ocean-driven moisture surge is pushing dew points significantly above their seasonal norms across Texas, the Southwest, and stretching into the Mississippi Valley and Gulf Coast states.

The Most Humid States So Far This June

Here are the states running the furthest above their average dew points from June 1 through June 20:

Texas: +5.1 degrees above average
New Mexico: +4.8 degrees above average
Arizona: +4.0 degrees above average
Louisiana: +3.9 degrees above average
Arkansas: +3.8 degrees above average
Maine: +3.5 degrees above average
Oklahoma: +3.4 degrees above average
Mississippi: +3.4 degrees above average
California: +3.2 degrees above average
Vermont: +2.8 degrees above average
Alabama: +2.7 degrees above average
Missouri: +2.3 degrees above average
Minnesota: +2.2 degrees above average

Illinois: +0.8 degrees
Indiana: +0.4 degrees
Kentucky: +0.2 degrees
New York: +0.2 degrees
South Carolina: -0.1 degrees

The States That Have Actually Felt Drier Than Normal

For residents from the mid-Atlantic through the Rocky Mountain West, June has brought a notable break from the sticky humidity that defined last year. The states running the furthest below their average dew points include:

Wyoming: -4.7 degrees below average
Idaho: -4.4 degrees below average
Utah: -4.0 degrees below average
Oregon: -3.6 degrees below average
Nevada: -3.7 degrees below average
Colorado: -2.7 degrees below average
District of Columbia: -2.4 degrees below average
Virginia: -2.3 degrees below average
Delaware: -2.1 degrees below average
Washington: -1.9 degrees below average
Maryland: -1.6 degrees below average
North Carolina: -1.2 degrees below average
Pennsylvania: -1.1 degrees below average
New Jersey: -1.1 degrees below average

A Big Change From Last June

This pattern represents a significant departure from June 2025, which was described as a very humid month across much of the country. The fact that large portions of the East Coast and mid-Atlantic are running below average this year is a notable contrast for residents who may remember last summer’s oppressive early season humidity.

Why Dew Point Matters More Than Temperature

Dew point is widely considered by meteorologists to be a more accurate measure of how uncomfortable the air actually feels than relative humidity. While relative humidity changes throughout the day as temperatures rise and fall, dew point stays more consistent and gives a truer picture of how much moisture is actually in the air.

A dew point above 65 degrees starts to feel noticeably humid to most people. Above 70 degrees, conditions feel oppressive. The states running 3 to 5 degrees above their seasonal averages this June, particularly across Texas, Louisiana, and the Deep South, are likely experiencing some of the most uncomfortable humidity conditions in the country right now.
