Dallas woke up today to partly cloudy, muggy skies and temperatures already in the low 80s, with the air feeling downright sticky in many neighborhoods. Over the next few days, it will be noticeably hotter and slower to cool off at night than what most locals think of as normal for mid-July. If you have outdoor plans, expect the combination of heat and humidity to make midday activity pretty uncomfortable.
This Afternoon Into Midweek
Sunny conditions are on tap for today, with a high near 98°F and a south-southwest breeze around 5 to 10 mph. Heat index values could push near 104°F this afternoon. That general pattern holds through tomorrow and on Tuesday, with highs near 100°F tomorrow, 103°F on Tuesday, and about 105°F by Wednesday. Overnight lows will generally sit in the upper 70s to low 80s, which means some neighborhoods may see nights that barely cool off, adding stress for people without reliable air conditioning. Forecasters say the chance for rain is small, and no watches or warnings are in effect right now, according to the National Weather Service Fort Worth.
Why It Matters
Prolonged daytime heat paired with warm overnight lows raises the risk of heat-related illness, especially for older residents, infants and anyone working outside. Hydrate, cut back on strenuous activity during the peak heat window from roughly midday through late afternoon, and check on neighbors, pets, and anyone who may be vulnerable. If you can, shift heavy outdoor chores to the morning or evening, and keep blinds or curtains closed during the hottest hours to help keep indoor temperatures down.
Where To Cool Off
If you need relief, the City of Dallas is encouraging residents to use public facilities such as recreation centers, libraries and select community centers as cooling sites during regular hours. Call ahead to double-check availability and times. The city also shares tips for saving energy while staying cool, and partner groups sometimes open extra hydration or cooling stations during stretches of intense heat. See details on cooling locations and hours at the City of Dallas cooling centers page.
