LAS VEGAS (KLAS) — Dangerously hot weather is settling in over the Las Vegas valley for the next 10 days, with temperatures expected to reach 118 degrees on Monday, potentially breaking the record for the highest official temperature for Las Vegas.

Since the end of May — except for a few days — triple-digit temperatures have baked the valley. And June was a record-setting month with 28 days reaching 100 degrees or higher.

The valley and surrounding areas are under an excessive heat warning from the National Weather Service which remains in effect through Monday, July 8, but could be extended. NWS said it’s leaning toward a higher probability of 118 degrees for Monday which could break the all-time highest official temperature for Las Vegas. The standing record is 117 degrees.

It’s also possible the record for the longest stretch of days at 110 degrees or higher is 10 days which has only happened two times since records began in 1937; most recently July 14-July 23, 2023. Previously it was in 1961.

Forecasted high temperatures for the upcoming 10 days are:

  • July 3 – 112

  • July 4 – 112

  • July 5 – 112

  • July 6 – 115

  • July 7 – 117

  • July 8 – 118 (possible record-setting day)

  • July 9 – 117

  • July 10 – 116

  • July 11 – 110 or higher expected

  • July 12 – 110 or higher expected

The heat wave impacts most of the West and is considered dangerous because the overnight low temperatures (90 degrees or above) are also above normal and won’t provide any relief. The effect of heat on a body over a prolonged time increases the risk of heat-related illnesses, including heat stroke which can be deadly.

During June, there were 108 complaints about heat and working conditions, according to Nevada OSHA. Last year, there were 27 similar complaints during the same time period.

Nearly one-third of June’s complaints were from the “accommodation and food industry,” according to OSHA’s records.
