LAS VEGAS — The city regularly experiences above-average warming, requiring local businesses to adjust hours during peak heat months.
In 2025, Las Vegas recorded 77 days at 100° or higher and 48 days above 105°. Local weather services said that Las Vegas had its warmest year on record in 2025 and is sure to set new records this year. In January 2026, afternoon highs reached the low 70s, which were 10 to 13 degrees above normal.
The intense heat during the summer months, from June through August, can affect local businesses, as daytime foot traffic declines. The high heat also adds the extra challenge of increased pressure on the power grid and potential outages. In previous heatwaves, like July 2024, city officials closed public pools, and the Neon Museum closed during the day. On places like the Strip, the usually packed afternoons grow quiet as visitors avoid walking outside in the heat. Many businesses, like the Neon Museum, had to shift to later operating hours.
Officials advise locals and visitors to avoid prolonged outdoor activity between 10 a.m. and 4 p.m., wear lightweight clothing and use sun protection.
