March Heat Wave in Las Vegas: Record Temperatures and Safety Advisory
A Historic Heat Wave
Recent weather patterns in Las Vegas have sent locals and visitors alike reeling, as Wednesday marked the hottest March day on record for the city. The mercury soared to a blistering 94 degrees at Harry Reid International Airport, breaking the previous record of 93 degrees that had been set just last year on March 26, 2022. According to the National Weather Service’s Las Vegas office, this extraordinary heat is expected to be short-lived, as Thursday’s forecast predicts even higher temperatures.
Local Meteorologist’s Advice
Meteorologist Brian Planz warns visitors to prepare adequately for the extreme heat. “If people are visiting Vegas this weekend, they just need to prepare for the heat, make sure they’re hydrating,” Planz cautioned. With predicted highs reaching 97 degrees on Thursday and 98 degrees over the weekend, this weather could lead to the earliest triple-digit temperature in the area’s history. There’s an estimated 50% chance of hitting 100 degrees on Friday and a 40% chance on Saturday.
Record-Breaking Trends
Historically, Las Vegas has never recorded a temperature of 100 degrees in March, nor in April. The earliest date for such a high temperature was May 1, 1947. Notably, the average daytime high temperature in mid-March typically rests in the low 70s, making these soaring temperatures a significant anomaly.
The heat wave sweeping across the Southwest is attributed to a heat dome, an unusual event for this time of year. Neighboring cities are experiencing similar extremes; Phoenix reached a staggering 102 degrees on Wednesday, while downtown Los Angeles registered 95 degrees, breaking a record set in 1997.
Warnings and Safety Precautions
Las Vegas is currently under an extreme heat warning that began Wednesday morning and will last until 8 p.m. Sunday. The unusual warmth this March follows a trend of record-breaking temperatures earlier in the month. Just on March 1, the airport notched an impressive 86 degrees, surpassing the previous record of 82 degrees established in 1986.
Outdoor Activities Affected
Trail Closures at Lake Mead
Due to the extreme heat, several popular trails in Lake Mead National Recreation Area have been closed for safety reasons:
- Goldstrike Hot Springs
- Arizona Hot Springs

- Lone Palm
Visitors hoping to explore these natural wonders should plan accordingly and consider alternative activities available in the cooler hours of the day.
