Las Vegas Braces for Surge in Temperatures and Monsoon Moisture This Week
Las Vegas is preparing for a notable shift in weather as daytime temperatures are set to soar, surpassing seasonal averages. Highs are expected to rise by at least five degrees above the normal temperature of 103°F by Wednesday, with forecasts predicting a peak of 111°F that day.
A high-pressure heat dome will settle over the four corners on Tuesday, contributing significantly to this increase in temperatures. Additionally, this high-pressure system is forecasted to push monsoon moisture back into southern Nevada, raising the chance of rainfall. Starting Thursday, the likelihood of rain will increase to 30%, with the most favorable conditions expected on Saturday.
As the week progresses, the UV index will reach very high levels, particularly on Sunday, which is anticipated to have a UV index of 10. The scorching heat is forecast to continue, with temperatures dropping slightly to 107°F on Thursday and 102°F on Friday. Thunderstorms are expected to develop on Friday afternoon and evening, bringing with them the potential for gusty outflow winds.
The expected high for Saturday is projected at 100°F, although storm chances are predicted to be lower in comparison to Friday. After the weekend, normal sunny conditions are anticipated to return, with temperatures climbing back to 105°F by Tuesday next week.
This spike in temperature comes amidst a summer characterized by fluctuating weather patterns. The year 2025 has already witnessed extreme heat, with Tuesday’s forecast tying for the hottest day at 112°F, though it fell short of breaking the existing record of 115°F, set in 1937. To date, Clark County has reported at least 87 heat-related deaths this year, emphasizing the seriousness of rising temperatures.
Interestingly, July was noted as the coolest July Las Vegas has experienced since 2015. While this year has seen some dry weather due to an active jet stream across the Pacific Northwest, monsoon moisture has primarily favored New Mexico and the Southern Plains, leaving Las Vegas with considerably lower rain levels since June 15. The Harry Reid Airport recorded merely 0.02 inches of rain, significantly less than the average of 0.50 inches for this period.
In addition to the rising temperatures, smoke from California wildfires has raised air quality alerts across the region, potentially affecting visibility and health conditions in Las Vegas. Weather patterns, influenced by the moving high-pressure system, are set to keep temperatures well above seasonal norms.
To ensure public safety during the extreme heat, cooling centers have been activated throughout Clark County. Residents are encouraged to utilize these facilities to avoid heat-related illnesses and ensure their well-being as temperatures rise.
