The National Weather Service has issued a heat advisory for the Las Vegas metropolitan area, with Wednesday expected to be the hottest day of the week. Temperatures are forecast to reach up to 110 degrees Fahrenheit, potentially breaking previous records for this time of year.

Why it matters

Extreme heat can pose serious health risks, especially for vulnerable populations like the elderly and those without access to reliable air conditioning. Local officials are urging residents to take precautions and limit time outdoors during the hottest parts of the day.

The details

According to the latest weather models, a high-pressure system moving into the region will drive temperatures well above average for this time of year. The Las Vegas valley is expected to see a high of 110°F on Wednesday, with overnight lows only dropping to around 90°F. This would eclipse the previous record high of 108°F set in 2018.

  • The heat advisory is in effect from 11 AM to 8 PM on Wednesday, April 8, 2026.
  • Temperatures are forecast to peak between 3 PM and 6 PM on Wednesday.
