A series of early summer heat waves have shattered single-day temperature records throughout the South and Southwest, breaking longstanding records in Texas and Florida, with “dangerously” hot conditions pushing north and west to California and the Pacific Northwest.
Tucson, Arizona, set a record daily high with thermometers reading 110 degrees, breaking the city’s previous record by one degree.

An excessive heat warning is in effect in Alabama, Arkansas, Arizona, Louisiana, Mississippi, Tennessee, east Texas and southern California, with heat advisories throughout the south and in California. An excessive heat warning had been in effect last week in more than half of Texas, including Dallas, Houston, Austin and San Antonio, bringing “dangerously hot conditions” and a heat index—how hot it feels outside when humidity is taken into consideration—as high as 120 degrees in some areas. Forecasters urged residents to stay hydrated in air-conditioned rooms, avoid strenuous outdoor activity and take “extra precautions” while outside. The heat wave is expected to expand throughout the south, bringing temperatures between five and 15 degrees above historical averages, according to AccuWeather meteorologists.
Forecasters expect the early-season heat waves to be a sign of things to come, as a weather phenomenon called El Niño develops, bringing warmer air north, and as scientists warn the effects of climate change from greenhouse gas emissions will continue to drive temperatures upward, prolong drought conditions and make wildfires more frequent and strong. Roughly 1,500 cities and towns in the U.S. broke daily heat records over a 30-day period ending last September, as heat waves spread throughout the U.S., as well as the U.K. and southern Europe. So far this year, a heat wave in China took down single-day records in China, while in the U.K., forecasters are warning of the hottest year on record.
A scorching 119-degree high at Big Bend National Park in west Texas on June 23 came within one degree of tying an all-time temperature record for the state of Texas, which has been in place since 1936.
