Some U.S. Cities Have Already Hit 90 Degrees. See When Your City Usually Tops 90.

90 Degrees Already? When Does That Usually Happen?

Parts of the U.S. received snow over the weekend, while others were sweating it out in 90-degree heat. The spring season has barely begun and several cities across the South are already feeling like summer.

With above average temperatures over the weekend, some areas across the South topped out well into the 90s and some even hit 100 degrees!

Oklahoma City’s high temperature on Sunday soared to 90 degrees. Dallas was even warmer at 93 degrees, which tied a record. The north Texas town of Vernon even hit 100 degrees, making temperatures feel much more like summer than spring.

Even cities as far north as Goodland, Kansas, and even Pueblo, Colorado have already experienced their first 90 degree day. In the East, Norfolk and Raleigh have both topped 90 degrees as well.

Phoenix, known for its heat, has also been breaking records lately. Their temperatures have been running 15-20 degrees above normal, which sent them into the triple digits this month. On April 11 they set a record high temperature at 103 degrees.

Places like Houston, Austin and Shreveport all hit that 90 degree mark back in March, and have experienced many summerlike days since. Del Rio, Texas hit their first 90 degree day back on February 8.

When The First 90 Degree Day Typically Occurs Across The U.S.

It’s not uncommon for some parts of the South to see their first 90 degree day as early as March or April, but for some regions, it’s much later.

Northeast

The larger cities in the Northeast, from Boston to Philadelphia, typically experience highs of at least 90 degrees beginning in late May or early June.

However, the first 90-degree day can occur much earlier. Washington, D.C., experienced its earliest 90-degree temperature on March 22, 1907.

Not all areas reach 90 every year. This includes Buffalo, New York, which did not observe a high of at least 90 as recently as 2014.

Midwest

The earliest 90-degree temperature on record for many cities in the Midwest is in April, although temperatures have climbed to 90 as early as March 21, 1907, in St. Louis and Kansas City.

The first 90 of the year has occurred as late as September, like it did in Chicago in 1915. There have also been some years where a few locations have not seen a high in the 90s, including Indianapolis in 2004.

South

Temperatures soar into the 90s earlier in the year across the southern tier – even as early as January. The earliest 90-degree high in Dallas was recorded on Jan. 31, 1911.

The average date when temperatures top 90 varies from early April in Miami to early June in Atlanta.

There have been years when the first high in the 90s wasn't observed until late June or July, including New Orleans in 1983, when the first 90-degree temperature was recorded on June 30.

West

The first 90-degree temperature typically occurs from late March into mid-April in areas of the Southwest and Southern California, where temperatures in the 90s have been recorded as early as January and February. Locations farther north, as well as in the higher elevations, wait much longer for temperatures to rise into the 90s. This includes Denver and Salt Lake City, which usually don't experience highs in the 90s until early June.

Mid- to late April is when the earliest highs in the 90s for the year have been recorded in Denver and Reno, Nevada. May is when the earliest first 90s of the year happened in Seattle; Cheyenne, Wyoming; and Albuquerque, New Mexico.

Temperatures do not reach 90 every year in some cities in the West. San Francisco is one example, where the highest temperature only reached 83 in 2018.
