Clark County has recorded 260 deaths where heat was a factor in 2025, officials said this afternoon.

The number could increase with 90% of cases taking up to 90 days to determine the cause and manner of death, officials said.

Those who died ranged in age from 18 to 91, the data showed.

This year’s heat death toll is a decrease from 2024, when July temperatures averaged nearly 100 degrees — almost seven degrees above normal. It was the hottest summer on record in Southern Nevada, and the county reported over 500 deaths related to heat.

By year’s end, Las Vegas had endured 112 days of triple-digit weather, surpassing the previous record of 100 days set in 1947. As a result, there were a record 526 heat-related deaths.

People can be more susceptible to dying from heat if they use certain drugs or have an illness or medical condition such as cardiovascular disease, the county said.

Officials said that behaviors like wearing inappropriate clothing for the heat, not drinking enough water, and not acclimating to the intense temperatures can also contribute to heat illnesses.
