Houston's summer evenings are getting warmer
Summer evenings are getting warmer in Houston and across much of the U.S. amid climate change, a new analysis shows. Why it matters: Higher overnight temperatures can have health consequences for vulnerable groups, as well as increased demand for air conditioning. That, in turn, can increase energy demand and strain electrical grids, fueling a vicious cycle with more greenhouse gas emissions. Driving the news: Average summer nighttime temperatures increased between 1970 and 2024 in 96% of 241 locations analyzed in a new report from Climate Central, a research and communications group. Among cities with an increase, temperatures rose by 3.1 degrees on average. Zoom in: Houston's overnight lows rose 5.8 degrees in that timeframe, according to the report. Dallas' rose 5 degrees, Austin rose 3.1 degrees and San Antonio rose 3 degrees. Between the lines: Hundreds of U.S. cities are experiencing more frequent warmer-than-average summer nights "with a strong climate change fingerprint," Climate Central says. That's based on the group's "Climate Shift Index" — a method of measuring climate change's impact on local daily temperatures — and the 1991-2020 climate normals.

Summer nights are getting warmer in Philly
Warm summer nights in Philly are starting to feel a little ... well, warmer. Why it matters: Higher overnight temperatures can have health consequences for vulnerable groups, as well as increase demand for air conditioning. That, in turn, can strain electrical grids and increase energy demand, fueling a vicious cycle with more greenhouse gas emissions. Driving the news: Average summer nighttime temperatures in Philly increased 4.1°F between 1970 and 2024, per a new report from Climate Central, a research and communications group. Nationwide, average summer temperatures at night increased in 96% of the 241 locations analyzed by Climate Central. Among cities with an increase, temperatures rose by 3.1°F on average. Between the lines: Hundreds of U.S. cities are experiencing more frequent warmer-than-average summer nights "with a strong climate change fingerprint," Climate Central says. That's based on the group's "Climate Shift Index" — a method of measuring climate change's impact on local daily temperatures — and the 1991-2020 climate normals.

Northwest Arkansas' summer night temps creep higher
Power couple Olivia Newton John and John Travolta likely weren't thinking of climate change when they sang about " Summer Nights" in the '70s. But those evenings have been getting warmer across Northwest Arkansas and much of the U.S. for 50 years amid climate change, a new analysis shows. Why it matters: Higher overnight temperatures can have health consequences for vulnerable groups, as well as increased demand for air conditioning. That, in turn, can strain electrical grids and increase energy demand, fueling a vicious cycle with more greenhouse gas emissions. Driving the news: Average summer nighttime temperatures increased between 1970 and 2024 in 96% of 241 locations analyzed in a new report from Climate Central, a research and communications group. Among cities with an increase, temperatures rose by 3.1°F on average. Zoom in: Northwest Arkansas' minimum temperature rose 2°F on average. It's 3.2°F in Little Rock and 1.8°F in Tulsa, Oklahoma. Zoom out: Reno, Nevada (+17.7°F), Las Vegas (+10°F), El Paso, Texas (+8.9°F) and Salt Lake City (+8.2°F) saw the biggest increases. What they're saying:"There's a lot of work ahead of us, and we don't have all the answers," Brian Beffort, sustainability manager for Reno's Washoe County, recently told the Las Vegas Review-Journal. "I'm focused on trees because they check the most number of boxes: They clean the air. They prevent stormwater. They cool things off ... There's a lot of planning that we need to do. But that's not the only intervention that we need." Between the lines: Hundreds of U.S. cities are experiencing more frequent warmer-than-average summer nights "with a strong climate change fingerprint," Climate Central says. That's based on the group's "Climate Shift Index" — a method for measuring the impact of climate change on local daily temperatures — and the 1991-2020 climate normals.

Summer nights in Salt Lake City are getting warmer
You're not imagining it: Your summer evening porch hangs are getting hotter. Why it matters: Higher overnight temperatures can have health consequences for vulnerable groups and boost air conditioning use. That, in turn, can strain electrical grids and increase energy demand, fueling a vicious cycle with more greenhouse gas emissions. Driving the news: Salt Lake City is among the U.S. locations that have seen the largest increases in summer nighttime temperatures between 1970 and 2024, according to a new report from Climate Central. By the numbers: 96% of 241 locations analyzed in the report saw a rise in evening temperatures, by 3.1 degrees on average. Salt Lake City's temperatures on average rose by 8.2 degrees. The latest: Rocky Mountain Power issued an advisory Wednesday, urging customers to conserve energy ahead of triple-digit temperatures hitting the valley, particularly during high-demand hours from 3 to 8pm. Zoom out: The higher temperatures in the evening are happening across much of the U.S. — especially in Nevada and other parts of the Southwest. Reno, Nevada (17.7 degrees), Las Vegas (10) and El Paso, Texas (8.9) saw the biggest increases. Between the lines: Hundreds of U.S. cities are experiencing more frequent warmer-than-average summer nights "with a strong climate change fingerprint," Climate Central says. That's based on the group's Climate Shift Index — a method of measuring climate change's impact on local daily temperatures — and the 1991-2020 climate normals.

Sweltering: Tampa sees warmest May morning on record
Jeff Berardelli is WFLA's Chief Meteorologist and Climate Specialist TAMPA, Fla. (WFLA) — Thursday morning's weather was so tropically warm and humid that it registered the warmest May morning ever recorded in Tampa. The thermometer never fell below 80 degrees, breaking the record for the highest minimum temperature at Tampa Airport since records have been kept in 1890. NOAA predicts above average 2025 hurricane season: Here's how many storms we could see This broke the daily record of 77 and the monthly record of 79. It's not coincidence, it's climate change. A Climate Shift Index analysis (from Climate Central) on Thursday morning's low temperatures across Florida showed that climate change made the warm temperatures at least five times more likely. But this is not a one-day thing. An analysis by WFLA shows that around 80% of the record warm morning lows in Tampa have occurred since the year 2000. Climate change is not only making the air warmer, but also the sea surface temperatures in the oceans and Gulf. The result of this is more humidity and warmer starts to the day, especially near the water. Slightly lower humidity has settled into Tampa Bay for the next 48 hours, so that means low temperatures will be slightly lower and more comfortable the next two days. But the humidity and heat will return for the second half of the holiday weekend. That means daytime heat index numbers near 105. Copyright 2025 Nexstar Media, Inc. All rights reserved.
