Texas cities swelter with 50+ more hot days, new climate study shows

Mother Nature is cranking up the summertime heat in Texas.

New data from Climate Central shows Houston and Austin are among nine major U.S. cities that now experience at least 50 more days per year with above-normal summer temperatures than they did in 1970. Other Texas cities that made the list were El Paso, McAllen and Tyler. Climate Central is a nonprofit organization that provides climate science research and analysis.

“Climate change is driving increasing temperatures across Texas and causing hotter summers. Austin and Houston now experience at least 50 more days above normal than they did in 1970,” said Kristina Dahl, vice president of science at Climate Central. “This isn’t just about discomfort; it’s about the growing risks to public health and infrastructure. We must prioritize climate resilience and stop burning fossil fuels to address these escalating challenges.”

For Austin, the number of above-normal-temperature summer days climbed by 50 from 1970 to 2024, according to Climate Central. During that period, the average summer temperature in Austin increased by 4.7 degrees.

In Houston, the quarter-century increase in the number of above-normal-temperature summer days was even higher — 56. The average summer temperature there rose by 4.6 degrees from 1970 to 2024, according to Climate Central.

Climate Central says that of the 242 cities it analyzed, 97 percent had seen a rise in the number of hotter-than-normal summer days (June, July and August) between 1970 and 2024. The study found the average jump in summer temperatures since 1970 was 2.6 degrees.

Outside Texas, cities on the list were Reno, Nevada; Albany, Georgia; Las Cruces, New Mexico; and New Orleans.

In the summer, the cities that warmed up the most from 1970 to 2024 were:

  • Reno, up 11.3 degrees.
  • Boise, Idaho, up 6.3 degrees.
  • El Paso, up 6.2 degrees.
  • Las Vegas, up 6.1 degrees.
  • Salt Lake City, up 5.9 degrees.

“As heat-trapping pollution continues to warm the planet,” Climate Central explains, “summer temperatures are arriving earlier and getting hotter — and dangerous heat extremes are becoming more frequent and intense.”

Climate Central’s study was based on weather data from the National Oceanic and Atmospheric Administration (NOAA).

A View From HETI

Artificial intelligence is now everywhere. It is mentioned in every startup pitch deck, and every corporate roadmap claims to use it. However, many early-stage businesses struggle with the simple question, “What does AI actually mean for my business?”

In a recent podcast episode of EnergyTech Startups, Merab Momen, founder of AI CTO Services and a long time AI practitioner, explains why most founders misunderstand AI, how startups can practically apply it and why Houston is quietly becoming a serious hub for AI-driven innovation.

Filling the AI Leadership Gap

Merab’s career has spanned decades of technology transitions. He worked on neutral networks in the 1990s, constructed computer vision systems long before they were common, and helped install AI solutions inside huge industrial companies. However, he noticed a huge problem when generative AI started to explode into the mainstream-The requirement of a real partner by the founders for AI integration but inability to rely on a full-time CTO and project-based consultants.

“I really needed something which is much more engaging where I can give that partner-level advice to the founders,” he said. By giving firms on-demand access to high-level AI knowledge and expertise, his methodology enables them to analyse tools, steer clear of cost blunders and eventually transition to a permanent technology leader when the time is right.

AI is Older than Most People Think

Despite its recent rise in popularity, AI is nothing new. AI actually began in the 1950s. Merab in his conversation explained how he worked on his first AI project back in the year 1996 that worked perfectly, but the processing power wasn’t just there to make it practical. He continued how he utilized the swarm intelligence models to optimize supply chains, now referred to as MLPOs and data engineering.

From Language Models to Physical World

Much of the public conversation about AI revolves around chatbots and text generation. But Merab sees far greater potential in AI’s interaction with the physical world, especially in industrial settings. He emphasized edge computing and vision language models (VLMs) as significant advances in manufacturing and energy. This physical shift is opening doors for new opportunities for robotics, automated inspections, and industrial safety applications. Merab added that Houston is uniquely positioned for this transition.

Why Houston has an AI Advantage

Silicon Valley may dominate the AI headlines, but Merab believes Houston’s advantage lies beneath the surface. The city doesn’t lag in AI utilization; it just operates in industries where results show differently.

Machine learning isn’t new to Houston’s core industries. Energy companies, manufacturers, logistics providers, and healthcare systems have been using advanced analytics for decades. The difference lies in them innovating in industrial sectors rather than consumer technology.

What’s Next

With the AI CTO Services growing, Merab is working with startups across industries to deploy AI in practical, business-first ways.

He is more interested in assisting founders in finding answers to critical issues than following new trends.

For Houston’s energy and climate tech community, it needs to transform AI enthusiasm into real-world impact.
