After seeing highs of 103 on Thursday, 102 on Friday and 100 on Saturday and Sunday, El Paso may – and we stress may – have seen its last triple-digit heat of a record-hot summer.

Monday will reach the high 90s and may hit 100, according to the National Weather Service, After that, forecasts for the remainder of August call for high temperatures ranging from the upper 80s to the mid 90s. One note of caution about forecasts: They are pretty reliable in the short term, but forecasts looking ahead 10 days or more are only accurate about half the time.

Looking ahead to September, 100-degree days in that month are rare in El Paso, even with the impact of climate change.

El Paso has had 29 September days above 100 degrees since 1900, the last time in 2020. The most triple-digit readings ever in September is four, in 1959 and 1979. The latest 100-degree reading ever recorded is Sept. 16, 1956.

So El Paso may not break the annual record of 62 days above 100 set in 1994. But 2023 has the second-most triple-digit days on record in a year.

Even if 2023 may not set a new record for triple-digit temperatures, it likely will be the warmest summer on record in El Paso, based on average daily temperature. This summer is trending to be almost a half-degree warmer than any previous summer on record.

July was the hottest month ever in El Paso weather records – by almost 3 degrees. June and July saw a record-shattering 44 consecutive days above 100.

Climate change is making El Paso summers hotter. Eight of the 10 warmest summers on record have come since 2011.

For record-keeping purposes, the National Weather Service identifies summer as June through August. 

This month also is on track to be the third- or fourth-hottest August ever in El Paso. 

Three of the four hottest Augusts on record for El Paso have occurred since 2019.
