Phoenix Breaks Heat Record Amid Rising Concerns Over Extreme Temperatures
Phoenix experiences 84 consecutive days of 100°F+ temperatures, breaking previous records. Extreme heat impacts multiple Southwest states, raising concerns about public health and heat-related deaths.
The city of Phoenix has extended its record-breaking streak of extreme heat, reaching 84 consecutive days with temperatures at or above 100°F (37.7°C) as of August 13, 2024. This surpasses the previous record of 76 days set in August 1993, highlighting the intensifying impact of climate change on the region.
The urban heat island effect significantly contributes to Phoenix's temperature woes. This phenomenon, which can cause temperature differences of up to 22°F between urban and rural areas, is particularly pronounced in downtown Phoenix. Building materials such as concrete, steel, and asphalt retain heat, preventing the city from cooling sufficiently overnight.
National Weather Service meteorologist Isaac Smith reported that temperatures were expected to reach 112°F (44.4°C) on August 14 and 114°F (45.6°C) on August 15, with no immediate relief in sight. An excessive heat watch was issued for the coming days.
The extreme heat is not limited to Phoenix. Las Vegas experienced a brief respite due to monsoon rainstorms, with temperatures dropping to 81°F (27.2°C) on August 8, the coolest since June 21. However, New Mexico was bracing for hotter weather, with Albuquerque expecting temperatures near 100°F (37.7°C) and even higher temperatures along the U.S.-Mexico border.
The prolonged heat wave has had severe public health consequences across the Southwest. In Maricopa County, home to Phoenix, officials confirmed 96 heat-related deaths as of August 10, with an additional 462 deaths under investigation. The county reported 645 heat-related deaths for the entire year of 2023.
"The rising toll of heat-related deaths is a stark reminder of the dangers posed by extreme temperatures. We urge residents to take necessary precautions and check on vulnerable individuals during this unprecedented heat wave."
In Clark County, which includes Las Vegas, 123 heat-related deaths have been confirmed this year. New Mexico reported over 760 heat-related emergency health clinic and hospital visits since April 1, with 29 occurring in the week leading up to August 13.
The extreme heat underscores the urgent need for adaptive measures and increased public awareness about heat-related illnesses. As temperatures continue to rise, cities across the Southwest are grappling with the challenge of protecting their residents from the deadly effects of prolonged exposure to extreme heat.
