Houston is waking up to another wall of humidity, with early readings near 79°F and the kind of sticky air that makes stepping outside feel like walking into a sauna. By this afternoon, temperatures are expected to climb close to 97°F, and the heat index could surge into the mid to upper 100s, making any extended time outdoors feel downright punishing. A slight chance of late-day showers or isolated thunderstorms might give a few lucky neighborhoods a brief break from the heat.
What To Expect Today
Highs are forecast to top out near 97°F, with humidity pushing heat-index values as high as 109°F, according to the National Weather Service Houston/Galveston. Southwest winds will stay on the lighter side, which means inland spots are likely to bake the most while the coast runs a few degrees cooler.
Rain chances remain low around 20%. Any shower that does pop up should be brief, and totals are expected to stay under a tenth of an inch. In other words, most of the city will be sweating it out with little help from the sky.
Afternoon Storm Chance
Scattered seabreeze-driven storms will be most likely after mid-afternoon, especially where outflow boundaries collide with the incoming sea breeze. That is where things could get briefly loud and soggy.
Any storm that manages to form could bring a quick burst of heavy rain and some gusty winds, but coverage is expected to stay isolated and hit-or-miss. If you have outdoor plans after about 3 p.m., it is smart to stay flexible and keep an eye on radar for fast-changing conditions.
Heat Safety And Cooling Centers
There are no official heat warnings posted this morning, but heat-index values are brushing up against Heat Advisory territory. It is a good day to go back to basics: drink plenty of water, avoid strenuous activity during the peak afternoon hours, and check in on neighbors and pets who might be more vulnerable to the heat.
For a list of local cooling resources or help finding an air-conditioned site, you can call 3-1-1 or visit Harris County Public Health. This pattern of hot weather is expected to stick around through early next week, so planning outdoor work and events with the heat in mind is not just smart, it is necessary.
