Houston weather feel like5/22/2023 Environmental justice advocate, Roishetta Ozane, reveals the social challenges in addressing the impacts of climate change, as devastating storms and a booming industrial buildout continue to engulf Southwest Louisiana-while leaving susceptible communities of color to fend for themselves."Anecdotally speaking, we’ve seen that a lot in recent years, where the heaviest rains will be inland," Lanza said. Galveston, on the other hand, saw a decrease in annual rainfall - by about 3.5 inches. "It was a pretty substantial increase, and I think a lot of that is attributable to Harvey," Lanza said. August saw the biggest increase with average rainfall increasing by about an inch. In Houston, the average yearly rainfall increased by about 2 inches. The "new normals" also include rainfall data. And it's not just a one-day temperature, we’re looking at the whole climatology."Ī climate assessment previously commissioned by the city of Houston found that the area will continue to see hotter days and nights, longer heatwaves and heavier rainfall if greenhouse gas emissions continue to rise. "It's another arrow in the quiver to show that things are warming. "It’s tough to really argue that climate change is not playing a significant role in what’s happening here," Lanza said. NOAA scientists say that nationwide the "new normals" reflect the impact of climate change. The only exceptions were November and December, which showed a slight decrease in average temperatures. Houston's average monthly temperatures got warmer in both the winter and summer months, according to data taken at Bush Intercontinental Airport. "It puts perspective around what the weather is doing at any particular time of year, how uncommon or how common it is." "It’s helpful in the sense that it lets us set the tone for what should be happening in an idealized world," said Matt Lanza, a meteorologist and managing editor for Space City Weather. These "climate normals" are what meteorologists use when they talk about typical weather in a city. The previous normals were based on data from 1981-2010. The so-called "new climate normals" are based on rolling averages of temperature and precipitation from the past 30 years, with the latest update reflecting weather data from 1991-2020. It mirrors a general trend across the country as the planet warms.Įvery 10 years, NOAA updates what it considers "normal " weather across the country.
