Record heat makes for a sweltering start to October in the West
The hot conditions are expected to persist over the coming days. Dozens of heat records could be set through the weekend from California to Colorado, including in Lake Tahoe, Reno, Las Vegas, Colorado Springs and Denver.
October’s warm start follows a summer of extreme temperatures. Both Arizona and California had their warmest summers on record in 2024, according to the National Oceanic and Atmospheric Administration.
Extreme heat is expected to worsen as a result of climate change. Studies have shown that as the planet warms, heat waves will become more likely, more intense and longer lasting.
