MORE INTENSE SEVERE WEATHER
Extreme rainfall has become more frequent and severe and is expected to worsen. As a result, there will be a significant increase in urban flooding — as much as 30-50% more than occurred over the last half of the 20th century.
Hurricane intensity is expected to increase significantly. Due to sea level rise, the risk of hurricane storm surge in some places along the Texas Gulf Coast may in 2050 be twice as high as it was around 1900.
HOTTER DAYS AHEAD
FIRST LOOK: EXTREME WEATHER UPDATE
Four charts from the 2024 update you need to know.
2022 saw a significant number of triple-digit days. 2023 was worse.
The long-term trend in the number of triple-digit days marches upward. 2023 witnessed record-high temperatures across the state continuing the trend described in the 2021 report. The 2021 report noted that the number and frequency of triple-digit days doubled since the 1970s. As of now, the average number of triple-digit days has tripled.
In 2023 we set the record of the average hottest temperature of a summer month.
In 2023, the average hottest temperature was 106°F, surpassing the previous record set in 2011. The primary difference from 2011 was that 2023’s heat persisted through most of September, while 2011 had already turned somewhat milder by then. The summer of 2022 also had some high extremes.
In a unique twist, Texas experienced the warmest coolest temperatures this summer.
Texans know the only break from summer heat happens at night. This summer cooler summer nights were harder to come by. In 2023, the coldest days in July and August got down to 64°F on average, which is the warmest on record, and 2022 ranked fifth warmest.
Following the extreme cold of 2021, the year 2022 was relatively mild, although temperatures did drop to their second coldest value of the 2000s so far.
Notably, 2023 was the mildest winter on record, as measured by the coldest minimum temperature observed on average in Texas. This is consistent with the warming trend that shows up in all seasons in Texas.
