Las Vegas, Nevada – Cooler air and fewer scorching days defined July 2025 in Las Vegas, giving residents a rare summer break from extreme desert heat. The city averaged 92.5°F for the month, making this the coolest July in a decade and well below the typical average, according to the National Weather Service in Las Vegas.
While most of July stayed dry—just 0.02” of rainfall recorded at the airport—flash flooding struck Northwest Las Vegas on July 18 after isolated, heavy downpours overwhelmed city drains. The warmest temperature of the month reached 112°F on July 14, but overnight lows dropped to 75°F on both July 26 and July 27, keeping conditions more comfortable for many valley neighborhoods.
Officials noted that flash flooding temporarily closed several intersections and prompted emergency crews to respond to stalled vehicles. Residents are urged to stay alert for rapidly changing weather, especially during monsoon season, and avoid driving through flooded roads. Even minimal rain can cause dangerous runoff in typically dry washes and intersections across Clark County.
July’s cooler trend follows several record-hot summers, offering a brief respite for Las Vegas. Warnings remain in effect for sudden storms through August, and the National Weather Service will issue new alerts as conditions change.
