Houston Area Faces 100-103 Degree Weekend as Extreme Heat Risk Extends Through August

3 articles · Updated · Space City Weather · Aug 21

Summary

  • Highs of 100 to 103 degrees are forecast across the Houston area this weekend, with the region under an extreme heat risk through the end of August.
  • High pressure peaking over Texas is driving the heat and should keep temperatures near 100 into next week, even as the ridge retreats slightly toward the Desert Southwest.
  • A weak boundary late Friday and a small chance of isolated storms Saturday could bring brief relief, but forecasters say many showers may fade before reaching Houston and Sunday looks mostly dry.
  • Houston logged its second 100-degree day of the summer on Thursday; while 2026 is still outside the city's 10 hottest summers, it sits only about 0.2 degrees short of entering that list.
  • Reliant urged residents to conserve power during the prolonged heat by raising thermostats when away, using smart devices and shifting heat-producing chores until after sundown.
