Some Hot Factoids About

Triple Digit Temperatures

 (100 F / 37.7777C *)

In El Paso, Texas

David Hefner / Climate Focal Point /  WFO El Paso

From 1879 through December 31,  2020 the Maximum Temperatures Has Reached 100 Degrees F or Higher 2295 Times.

On the "Average" El Paso Experiences 15.4 Days or Triple Digits Per Year. 

* From 1981-2010 El Paso Averaged 20.5 Days of Triple Digits Per Year. * 

Since 1879 No Year Has Gone Without at Least One Triple Digit Occurrence.

The Following Years Saw Only One Occurrence of Triple Digits. 

1899 1904 1914 1917 1919 1926 1941 1967

 The Hottest Day (114 F) In El Paso Occurred on June 30, 1994. 

1994 Also Was the Year a Record Consecutive 23 Days of Triple Digits Occurred from June 23 Through July 15. 

The Earliest Occurrence of 100 Degrees was on May 7, 2020. 

The Latest Start Time of 100 Degrees was on September 2, 1899. 

The Latest Occurrence of 100 Degrees was on September 16, 1956 (101 F). 

The 'Average' Starting Date for Triple Digits is June 14. 

The 'Average' Ending Date for Triple Digits is August 2.

MONTHLY FREQUENCY DISTRIBUTION OF TRIPLE DIGITS

(Number Per Month and Percentage)

MAY JUNE JULY AUGUST SEPTEMBER
56 925 699 303 31
2.6% 45.9% 34.7% 15.0% 1.5%

Note the asymmetric distribution about July centered on June. June is the month with the highest solar angles and longer days but July through mid September host the rainy season in El Paso (the monsoon shift of the prevailing west winds to the east) in which around 50% of the  annual precipitation falls...skewing the temperature curve. 

-------

Synoptic Consideration: Triple digits are most likely, especially in runs of consecutive days when subtropical high pressure aloft (associate with subsidence-downward motion in the atmosphere which in turn warm the atmosphere and suppresses cloud and thunderstorm development) positions itself over New Mexico and/or Arizona and New Mexico rather than to the east of New Mexico (which is favorable for moisture input).

FREQUENCY DISTRIBUTION OF THE TEMPERATURES THEMSELVES

TEMP 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114
 % 29.38 20.57 16.17 10.57 7.25 6.27 3.37 1.81 1.71 .52 1.55 .47 .21 .10 .05

 77% OF THE TRIPLE DIGITS ARE <= 103 F

 The Probability Density Function of the Triple Digits Can Be Represented by an Exponential Decay Function of the Form:

P(T) = A*e(B/T)

Where T = Temperature in Deg F...A = 2.433*10(-18)......e=2.71........B=44.01.735

-------------------

Most Likely Time to Encounter Triple Digits: 

There is a 67% Likelihood of Having a Triple Digit Between June 11 and July 18.

Both June 23 and June 28 Have Each Seen the Most Days (49) with Triple Digits since 1879.

Note TEMPS 1879-1886 Show High Bias Due to Shelter Location:
