Las Vegas Braces for Monsoon Season and Extreme Heat
Las Vegas is preparing for a return of monsoon moisture, with showers and thunderstorms anticipated in nearby Mojave County on Friday. While the city itself has a marginal chance of experiencing thunderstorms on the east side Friday night, forecasts indicate a slightly better likelihood of rain on Saturday.
Breezy conditions are expected to prevail throughout most of the weekend in Las Vegas, with daytime temperatures remaining near seasonal averages. Although little change in temperature is projected for Sunday, drier and warmer air is set to return on Monday as the monsoon moisture begins to retreat. Daytime highs could soar to between 107 and 109 degrees on Wednesday and Thursday, respectively.
The UV index for Saturday has been rated at 10, categorizing it as very high. Residents are advised to take precautions to protect themselves from the sun, especially given the ongoing heat wave.
Record Rainfall and Recent Weather Patterns
This year, Las Vegas has already experienced its wettest May on record, with 1.44 inches of rainfall recorded at Harry Reid International Airport, vastly surpassing the typical average of just 0.07 inches. However, since the official start of the monsoon season on June 15, only a meager 0.02 inches of rain has been observed, falling below the average of 0.50 inches for this time frame.
Recent thunderstorms in the area were attributed to a cold low-pressure system, rather than the anticipated monsoon moisture. In general, summer weather in Las Vegas has been greatly influenced by an active jet stream, resulting in predominantly dry conditions.
Heat Warnings and Health Alerts
In addition to thunderstorms, an extreme heat warning has been implemented following a particularly sweltering day on Tuesday, where temperatures reached an alarming 112 degrees, tying for the hottest day of 2025. To date, there have been reports of at least 87 heat-related deaths in Clark County this year, underlining the seriousness of the heat wave.
Furthermore, smoke alerts have been issued due to wildfires in California impacting air quality across the Las Vegas Valley. Residents are encouraged to remain alert and consider limiting outdoor activities when air quality dips.
Preparing for Monsoon Threats
The official monsoon season runs from June 15 to September 30 in Southern Nevada, with the most intense activity typically occurring in July and August. With the potential for more moisture attempting to re-enter the area next weekend, Las Vegas residents are urged to remain vigilant and prepared for varying weather conditions as summer progresses.
