Cold/Wind Chill in Coastal Willacy, Texas

Interpolation between the The Texas Coastal Ocean Observation Network (TCOON) site at Rincon del San Jose along Laguna Madre in southeast Kenedy County, with a TCOON site at Realitos Peninsula in northeast Cameron, suggested up to 12 hours of wind chill at or below 30F (Cold Weather Advisory Criteria) on January 25th from roughly 1224 AM to 1224 PM CST on the morning of Sunday January 25th. Wind chill values likely bottomed out in the mid 20s for a few hours around daybreak.

An Arctic cold front ushered in the coldest air mass of the season to Deep South Texas and the Rio Grande Valley with widespread cold temperatures between January 25-27, 2026. Cold temperatures (wind chill) below 30F arrived during the late evening of the 24th across the ranchlands and spread to the lower Rio Grande Valley before daybreak on the 25th. A cold afternoon set the stage for the overnight of the 25th into the morning of the 26th, as skies cleared but fresh breezes/stronger winds near the coast prevailed. The 26th was the coldest ambient and feels-like temperature of the calendar year so far, with a freeze in all areas, and wind chill below 20F in most areas.

Clear skies and calm winds allowed rapid temperature drops during the evening of the 26th, with many inland locations recording their second hard freeze in as many nights early on the 27th. Locations closer to the coast saw winds veer to the northeast above the surface, precluding a second freeze/hard freeze.

The hard freeze caused minor damage to tender vegetation and crops in Hidalgo, Willacy, and Cameron County. Dollar values were unknown as of this writing (end of March 2026) but some estimates are included, and will likely be updated.
