Heat in Brooks, Texas
Heat June 17, 2026 · Brooks, Texas
What the National Weather Service wrote
The combination of hot temperatures near 100 degrees and high humidity, a remnant of rainfall associated with tropical moisture as Tropical Storm Arthur began to form, created heat index values between 111 and 114 at Brooks Co. Airport near Falfurrias, with peak values briefing reaching 115 degrees.
The wider storm
As developing Tropical Storm Arthur moved along the middle Texas coast (June 17) and as a degenerated low pressure system along the Louisiana Coast (June 18), very hot air descended on the southern tip of Texas, with record extreme heat index, or feels-like, temperatures for the entire region on the 18th. The high heat index values held on into June 19th, before unsettled weather brought slightly lower temperatures and pockets of rain by the 20th, which ended the short but brutal window of extreme heat.
