Record highs were tied or broken at Intercontinental Airport, Hobby Airport, and in Galveston on Monday, and more heat is on the way.
Highs reached or exceeded 100 degrees with heat index values hovering between 105 and 110 during the hottest part of the afternoon.
Tuesday's high should be near 102 in Houston and between 95 and 100 along the coast. Heat indexes will again push 110 in the afternoon.
There will be some relief as an afternoon sea breeze begins to kick in by mid-week. That should keep temperatures in the 90s, but it will also increase humidity levels for the second half of the week.
Drink lots of water and take plenty of breaks if you're doing anything strenuous outside this week.
"You want to avoid liquids with a lot of caffeine or sugar because that's just going to accelerate the body fluid loss," said Porfirio Villarreal with the Houston Department of Health and Human Services.
Wear light-weight, light-colored, breathable clothes to help stay as cool as possible, too. Exercising early in the morning or late in the day in order to avoid the hottest part of the day is also recommended.
In Wiley Park in the Fourth Ward, Local 2 saw kids finding the perfect place to stay cool -- at a splash pad.
The experts said it's a good idea to closely watch the young and the elderly because they are the most vulnerable in this hot weather.
