In brief: Today’s post starts out with lyrics from Green Day, which should say something about the invariability of our weather in the days ahead. But anyway, September has ended, October is here, and our eternal watch for fall-like weather continues.
September ends
Summer has come and passed
The innocent can never last
Wake me up when September ends
Those are the opening lines of Green Day’s iconic song “Wake me up when September ends.” It actually has nothing to do with summer or weather (it’s about the death of the singer’s father), but the lyrics were running through my mind yesterday. In Houston you very well know August is always going to be scorching. You know September is going to be hot too, but with one or two fleeting fronts there is some hope for slightly cooler nights.
By October, well, that is when we can have some expectation of starting to see real cold fronts that knock nighttime temperatures into the 50s. Some days in the 80s with dry air. Alas, here we are on October 1, 2025. And there is no sign of such a front. In fact, the first 10 days of the month look very much like September. So maybe go back to sleep for awhile longer, everyone.

Wednesday and Thursday
These will be fairly hot and sunny days, especially for October. We are unlikely to set high temperature records, but the city will flirt with them. In central and southern areas, highs should reach the lower 90s, but for inland areas north and west of downtown, highs could reach the mid-90s. This is partly because afternoon dewpoints should fall to around 60 degrees. So it will be a slightly drier heat, as we’ve seen the last couple of days. Winds will be light, from the north at about 5 mph. Lows will be in the lower 70s. Rain chances are basically zero.
Friday, Saturday, and Sunday
With a more easterly flow setting up for this weekend we will see humidity levels increase somewhat. We are not going to feel summertime humidity levels, but it will still be sticky compared to what we’ve experienced the last several days. This increased moisture level should take a little bit of the top off of daily highs, with the region reaching the upper 80s to lower 90s. Skies should be mostly sunny. Nights will be slightly warmer, in the low- to mid-70s. And there will be some slight rain chances on Friday and Saturday, perhaps getting up to 30 percent or so by Sunday. Basically, if you live south of Interstate 10 there’s a puncher’s chance of a passing shower, with the best odds right along the coast. If you live further north, you may be better off playing the lottery.

Next week
To be honest, not much appears to change for the majority of next week. What you see this weekend you’re likely to see for much of next week. Maybe that begins to change toward the end of next week. But also, maybe not.
