News Summary
Las Vegas is on track for its coolest July in ten years, with current temperatures averaging 92.5 degrees. This drop follows last year’s historic heat. The unusual weather pattern, influenced by high-pressure systems, has contributed to significant temperature changes across the region. While August may see a return to heat, residents have been cautioned about potential fire hazards due to windy and dry conditions. Thunderstorms have also led to flooding and power outages, prompting safety advisories for local residents and pet owners.
Las Vegas is on track to experience its coolest July in a decade, with average temperatures projected to be significantly lower than historical norms. The average temperature recorded at Harry Reid International Airport through July 29 is 92.5 degrees, marking a drop of 0.9 degrees below the typical averages seen from 1991 to 2020. If trends hold, July 2025 will be recognized as one of the rare months in the last quarter-century to deliver below-average temperatures.
In stark contrast, last year saw Las Vegas enduring its hottest month in recorded history, with temperatures averaging 99.9 degrees—6.5 degrees above the seasonal average. The record-setting heat in July 2024 peaked with a shocking high of 120 degrees on July 7, a new all-time record since the inception of temperature recording in 1937. Notably, the ten hottest months ever recorded in Las Vegas’s history have all occurred within the past two decades.
This July’s unusual weather is attributed to a strong dome of high pressure dominating the central United States, which has facilitated extreme heat in areas east of the Rockies. Cities such as Tampa and New York City have felt the heat acutely. Tampa set an all-time high of 100 degrees on July 27, while New York City reached 97 degrees on July 29. Furthermore, Extreme Heat Warnings have been issued across the Mid-South due to dangerously high heat indices, which soar past 115 degrees, primarily exacerbated by high humidity levels.
As the forecast looks ahead, the Climate Prediction Center indicates that Las Vegas faces a 28% chance of maintaining below-average temperatures in August. Conversely, there is a 39% likelihood of a return to above-average temperatures, with the forecast suggesting that high pressure systems may once again settle over the Desert Southwest. The usual average high temperature for August in Las Vegas is around 103 degrees.
Residents of Southern Nevada can expect mostly sunny and seasonably warm weather for the upcoming weeks, with anticipated high temperatures around 104 to 105 degrees. In addition, wind gusts in the region are projected to fall within the 20-30 mph range. A recent Red Flag warning was issued in Las Vegas over Independence Day, cautioning of fire hazards due to hot, dry, and windy conditions. Winds were recorded from the south at 15-25 mph, with gusts reaching up to 30 mph, which brought fire smoke from the ongoing Madre fire in Southern California, adversely affecting local air quality.
This July also saw thunderstorms that resulted in flooding and stranded individuals in flood channels. Las Vegas Fire & Rescue was dispatched to provide assistance to two individuals who required rescue following the flooding in the area. Additionally, recent weather events caused outages affecting approximately 5,000 customers in Las Vegas.
Pet owners are further advised to take precautions as pavement temperatures can reach as high as 140 degrees in midday summer heat, posing serious risks to animals. As the city navigates between extremes, residents are urged to stay informed about the weather and prepare for potential fluctuations in temperature and conditions in the coming weeks.
