Monday, June 29, 2026, Austin rolled out of bed to about 79°F and air that was already humid under mostly clear-to-hazy skies. The city is headed for a hot and gusty afternoon, with highs expected to climb into the upper 90s and the heat index nudging into the low 100s. Southerly winds are set to stay brisk through the day, with afternoon gusts that may approach 25 to 30 mph. A plume of Saharan dust moving over the Gulf is likely to give the sky a milky look and could help paint an extra-bright sunset tonight.
Afternoon Heat And Haze
Forecasters are calling for a high near 98°F Monday, with haze developing after about 1 p.m. and heat index values around 102°F. South winds should run about 5 to 15 mph, with gusts reaching roughly 25 to 30 mph. The Saharan dust is concentrated around 5,000 to 6,000 feet, but some of it may mix down closer to the surface this afternoon, which would keep skies looking washed out and boost the odds of vivid colors at sunrise and sunset. For full details, see the National Weather Service Austin/San Antonio.
What To Expect This Week
Dry and hot conditions should hang around through the week, with daytime highs mostly in the mid to upper 90s and peak heat indices in the 100 to 105 range, especially east of I‑35. Rain chances stay small, and daytime winds are expected to gradually ease later in the week, although some afternoon gusts may linger at times. For background on the dust plume and earlier coverage, see the write-up on Austin's steamy sauna as the heat index flirted with triple digits.
How To Stay Comfortable
Try to limit strenuous outdoor activity during the hottest hours of the afternoon, drink plenty of water, and check on older neighbors and young children. People with asthma or COPD may be more sensitive to the dust, so consider cutting back on time outside and keeping an eye on local air quality readings. Secure lightweight outdoor gear, since those southerly gusts can tug at canopies and tents, and when you can, shift events to the morning or evening when temperatures are less punishing.
