The highest temperature recorded today, excluding the heat index, was 98 degrees, surpassing the previous record of 96 degrees set on July 14, 2021, according to the National Weather Service (NWS).

What is the Heat Index and Why Does It Matter?

The heat index combines temperature and humidity to determine how hot it feels. Today’s reading of 98 degrees reflects the actual air temperature, not the perceived heat. The NWS emphasizes that extreme heat can pose health risks, particularly for vulnerable populations. “This is a critical distinction for public safety,” said Dr. Sarah Mitchell, a climatologist at the University of Arizona. “Understanding the difference helps communities prepare effectively.”

How Does This Compare to Past Records?

Today’s 98-degree mark breaks the previous record of 96 degrees, which had stood since 2021. The NWS noted that this is part of a broader trend of rising temperatures in the region. “We’re seeing more frequent and intense heat events,” said NWS meteorologist James Rivera. “This aligns with climate models predicting higher baseline temperatures.”

What Are the Impacts of This Heatwave?

Local authorities have issued heat advisories, urging residents to stay hydrated and avoid prolonged outdoor exposure. The city’s public health department reported an increase in heat-related emergency calls compared to the same period last year. “We’re seeing a clear correlation between temperature spikes and health incidents,” said Dr. Emily Zhang, a public health official. “This underscores the need for adaptive measures.”

What’s Next for the Region’s Climate?

Climate experts warn that such records may become more common. A 2023 study published in *Nature Climate Change* found that global warming has increased the likelihood of extreme heat events by 50% in the past decade. “This isn’t an isolated incident,” said Dr. Michael Torres, a climate scientist at MIT. “Without significant mitigation, we can expect more records to fall.”
