Austin Weather: Cool June! Is the Texas Heatwave Finally Over?
Austin, Texas, experienced a surprisingly mild June this year, offering a welcome respite from the scorching heat typically associated with the Lone Star State. For the first time since 2019, the city didn't record a single day exceeding 100 degrees Fahrenheit. Data from the National Weather Service reveals the hottest day of the month peaked at a comfortable 99 degrees on June 9th.
Last year, Austin endured four days in the triple digits during June, while 2023 saw a staggering 15 days over 100. The heatwave of 2022 was even more intense, with 21 days of extreme heat. However, 2025 hasn't been entirely without its scorching moments. A significant heatwave impacted Texas, including Austin, back in May, with forecasters describing it as "one of the more dramatic temperature swings in recent memory." The city reached 100 degrees on May 13th and 14th.
Adding to the interesting weather patterns, sea-breeze showers have become a regular occurrence in Austin. These showers are a result of Austin being positioned between three distinct weather systems: high atmospheric pressure to the east, a trough of low pressure to the northwest, and tropical moisture to the southwest.
What are Sea-Breeze Showers?
Sea-breeze showers develop when enough moisture is present. The sun heats the land, causing surface air to rise, condense into clouds, and produce rain and thunderstorms. These storms usually originate closer to the coast and, due to consistent south-to-southeast winds, travel into Central Texas in the late afternoon or early evening. Interestingly, they often weaken as they reach the I-35 corridor and encounter drier air.
The Impact of Tropical Storm Barry
The remnants of Tropical Storm Barry, which made landfall in central Mexico, have also played a role in the recent weather. As they drift through South and West Texas, they bring showers and thunderstorms to the Rio Grande region, Edwards Plateau, and Hill Country. Furthermore, the clockwise airflow of a high-pressure system pulls in abundant atmospheric moisture from the Gulf of Mexico, contributing to the sea-breeze showers and thunderstorms in Austin.
Keep an eye on the skies, Austin! The weather is dynamic and full of surprises.
