July Climatology

A hot and rain-free forecast is expected across the region for the Independence Day holiday. Skies will range from partly cloudy to mostly sunny, with high temperatures in the mid-to-upper 90s for most areas and near 100°F along the Rio Grande. When humidity is factored in, afternoon heat index values will climb over 100°F for many, peaking between 103°F and 107°F across the Coastal and Rio Grande Plains. Southeast winds will continue at 8 to 15 mph with higher gusts.

This graphic provides essential heat safety tips for anyone attending outdoor events during the summer heat, particularly this holiday weekend. Key recommendations include: drinking plenty of water and encouraging those with you to do the same; wearing a hat, lightweight, loose-fitting, and light-colored clothing, and applying sunscreen; utilizing cooling tools like handheld fans or cooling towels; taking frequent breaks under shade, in cooling tents, or misting stations; and immediately seeking medical assistance at the first signs of dizziness or weakness.

Typical mid-summer heat will dominate the 7-day outlook, spanning July 4th through July 11th. Afternoon high temperatures will consistently stay in the mid-to-upper 90s for the majority of locations, while Del Rio will see triple-digit highs reaching up to 102°F. Low temperatures will stay warm, primarily in the 70s. The entire forecast period is expected to be predominantly rain-free, with the sole exception of Tuesday, which features a slim 5% to 20% rain chance for central and eastern areas.

The latest monthly outlook from the Climate Prediction Center suggests likely warmer than normal conditions for July 2026 over South-Central Texas. Odds are tilted slightly towards drier than normal conditions for the region.

July is typically one of the hottest months of the year for South-Central Texas, just behind August. Several days with highs in the low triple digits are typical for the month.
