Find out this Summer's Warmest States in the U.S.

With the beginnings of summer marked by humid, hot weather, a new map released by the National Climatic Data Center (NCDNC) shows many areas infamously known for their warm temperatures and what to expect in the future. 

"The temperature increase after the solstice occurs because the rate of heat input from the sun during the day continues to be greater than the cooling at night for several weeks, until temperatures start to descend in late July and early August," explained NCDC.

The map and the analysis is based on climate data from 1981-2010. 

The map goes in-depth by illustrating the "warmest day of the year" depending on how variable the climate of the United States can be. In other words, June in New Mexico and Arizona often reflect the North American Monsoon-a period of increased rainfall that affects part of the Southwest U.S. As these areas tend to be cloudier and wetter during the humid months of July through September, the temperature is shown as the highest on average in June.

The NCDC noted that most locations in the United States still have a ways to go before their usual warmest day of the year. However, according to their research, the hottest days of the year are most likely to be in middle or late July.
