The Hot Box

Seven facts about summertime in Southern Nevada

The hottest city is Laughlin, says Barry Pierce, meteorologist at the National Weather Service in Las Vegas. The reason: It sits in the Colorado River Valley, at a lower elevation than Las Vegas, which is typically 10-12 degrees cooler.

The sudden burst of wind that comes out of nowhere every summer afternoon is the result of convection, the process in which hot air rises and cooler air replaces it, Pierce says.

The hottest time of day in Las Vegas is between 4:30 and 5:45 p.m., Pierce says. It varies because after the sun reaches its maximum angle at noon it still heats the ground as it heads for the horizon.

There are 22 public pools in the Las Vegas Valley this summer: eight operated by the Clark County Parks and Recreation Department and 14 run by municipalities.

There are 32 ice cream trucks roaming the Valley each summer day (based on the 32 business licenses issued to ice cream-specific mobile food vendors).

Nobody at Aarrow Advertising, a local sign spinning company, gets a raise for working in hot weather. (The company only gives performance-based increases).

The Walgreens in front of the Palazzo has to restock sunscreen at least three times a day. No wonder it is the highest-grossing link in the drugstore’s chain.
