North Las Vegas ZIP Code 89030 Appears in Heat-Vulnerability and Overdose-Risk Analysis
A Southern Nevada Health District analysis identifies ZIP code 89030 among nine 2024 overlap areas as North Las Vegas faces an extreme heat warning through Sunday, August 2.
ZIP code 89030, which includes part of North Las Vegas, is among nine Clark County ZIP codes identified in a Southern Nevada Health District analysis of overlapping heat vulnerability and overdose mortality.
The finding comes as North Las Vegas remains under an extreme heat warning until 8 p.m. PDT Sunday, August 2, according to the National Weather Service Las Vegas office. Forecasters say highs across the Mojave Desert could reach 110 to 120 degrees, with overnight lows of 80 to 95 bringing little relief.
KTNV reported the North Las Vegas connection on July 28, drawing attention to a health-district bulletin based on 2024 ZIP-code data. The analysis is not a real-time measurement of conditions in 2026, but the current warning makes its public-health implications more immediate for residents without reliable air conditioning, shelter or easy access to cooling.
What the ZIP-code analysis found
Southern Nevada Health District epidemiologists used a Getis-Ord Gi* hot-spot analysis in ArcGIS Pro to examine ZIP-code-level patterns. The analysis identified statistically significant clustering of both heat vulnerability and overdose mortality in nine ZIP codes: 89030, 89101, 89102, 89104, 89106, 89110, 89121, 89142 and 89169.
The bulletin says the areas are primarily concentrated in central and eastern Las Vegas. ZIP code 89030 includes part of North Las Vegas, but ZIP codes do not map perfectly to city boundaries.
The result is an area-level statistical signal. It does not rank North Las Vegas ZIP codes, establish that 89030 has the city’s highest heat-death or overdose rate, predict an individual’s risk or prove that extreme heat causes overdose deaths in every location or for every resident.
Broader findings and proposed response
The bulletin reports that annual average land-surface temperatures in the Las Vegas area rose 7.5 degrees Fahrenheit from 1984 through 2024. It also says the age-adjusted overdose death rate for all substances increased from 22.2 per 100,000 people in 2011 to 32.0 in 2024.
Using death-certificate data from 2018 through 2024, researchers found overdose deaths peaked during the summer months, particularly deaths involving methamphetamine and all opioids combined. A Poisson regression model found a 0.54% increase in overdose-death risk for each 1-degree increase in daily maximum temperature. That is a population-level statistical association, not proof of a direct cause in an individual case.
The health district says it and its partners will explore targeted outreach in the identified ZIP codes, including increased naloxone distribution and heat-health education during high-risk summer months. The bulletin describes those as proposed next steps, not a confirmed completed program.
What North Las Vegas residents can do now
The National Weather Service advises drinking plenty of fluids, staying in an air-conditioned room or other cool shelter, avoiding the sun and checking on relatives and neighbors. Outdoor work and strenuous activity should be limited to early morning or evening whenever possible.
Southern Nevada Health District guidance identifies infants and young children, older adults, people with chronic health conditions and people without working air conditioning or shelter as being at higher risk. Carry water, seek shade and check on people who live alone or may need assistance. During extreme heat, the hottest part of the day is often from 10 a.m. to 6 p.m.
Heat stroke is an emergency. Warning signs include a body temperature of 103 degrees or higher, headache, red, hot, dry skin, a strong pulse and loss of consciousness. Call 911 if heat stroke is suspected and move the person to a cool, shaded location while help is coming.
Cooling options in North Las Vegas
Clark County’s published July cooling-station schedule listed North Las Vegas locations including The Salvation Army at 35 West Owens Avenue, the Neighborhood Recreation Center at 1638 N. Bruce Street, Pearson Community Center, Alexander Library, Silver Mesa Recreation Center and Skyview Multi-Generational Center.
That PDF specifies operating dates of July 20 through July 24, 2026 for the listed daytime cooling stations. It does not confirm that every site is open during the August 1-2 warning. Residents who need a cool place should check Clark County’s current cooling-station page and verify hours by phone before traveling.
The warning is scheduled to remain in effect until 8 p.m. PDT Sunday, August 2. Residents should monitor updated forecasts and warnings before making plans.
