No 100-degree days in Houston this year—yet

As noted Monday, Houston has reached the peak of summer. However, we’ve yet to record any 100-degree days. The highest mark recorded at Bush Intercontinental Airport has been 97 degrees, which the city has reached three times. This isn’t all that abnormal, as we usually see most of our 100-degree days in the coming month or so. But still, it is another indicator that, so far at least, conditions for Houston during the summer of 2019 have been fairly moderate. With that in mind, here is some 100-degree day climatology for the city of Houston:

  • Earliest 100-degree day: June 2, 2011
  • Average first 100-degree day: July 24
  • Average number of 100-degree days: 5-7

It does not appear as though we will see any 100-degree days this week, although we can’t entirely rule that out. Mid-90s are most likely, however.

There will be plenty of 100-degree marks in Texas on Wednesday, but Houston is unlikely to be among them. (Pivotal Weather)


Today will see a pretty healthy chance of storms; with a combination of daytime heating in the mid-90s for most of the region, plenty of atmospheric moisture, and an upper level disturbance sliding into the area this afternoon and evening. High resolution models suggest the better rain potential will be to the east of Interstate 45, but truthfully the entire region will see at least 40 to 50 percent rain chances, especially from about 3pm to 10pm. We probably will see a few bullseyes above 1 inch, with more widespread average of a few tenths of an inch. Lows tonight will be in the upper 70s, with very warm conditions along the coast—Galveston established a record high minimum Monday with a morning low of only 84 degrees, breaking the previous record of 83 degrees set in 2013.

Wednesday and Thursday

These will be sunnier days, with highs again in the mid-90s. Rain chances will dial back a bit, but still should rise to about 30 to 40 percent during the afternoon hours. Accumulations, again, will likely be measured in tenths of an inch for areas that do see rain.

Better rain chances this week will come to the east of Houston, over the Beaumont area. (Pivotal Weather)


Sunny and warm, with highs in the mid- to upper 90s.

Saturday and Sunday

The weekend still looks mostly sunny, with only slight 10 to 20 percent rain chances during the afternoon hours. The big question is temperatures, and these are days that parts of the metro area may well tick into the upper 90s, and possibly threaten the century mark. Either way, it will be hot, so if you have outdoor plans, please stay hydrated.

Next week

The overall pattern doesn’t change a whole lot next week, as we continue to see a mix of heat and low to moderate rain chances. For now, I’m happy to report that there’s nothing too extreme on the horizon.

    Similar to not speaking of a pitcher in the midst of throwing a no-hitter, this too should apply.

        Similar to the odds of a no-hitter actually being completed, it’s still early in the “ball game” and the likelihood of not reaching the century mark is, well, you know… Let’s just see if it can get stretched out until the 8th or 9th inning.

    It’s been well over a month without measurable rainfall in the Meyerland area. Can you hook us up Eric?

      Be careful what you wish for … but hopefully you get some today or Wednesday.

      Matt will have a tropical update today or tomorrow. We have no concerns right now.

    “Earliest 100-degree day: June 2, 2011”

    It is fitting that it occurred in 2011 – – The Summer From Hell. If memory serves, August of that year saw 30 out of 31 days with highs of 100-degrees or more. By comparison, thus far this summer has been a walk in the park.

      If I remember right, the humidity was pretty low! I guess that allowed the temps to climb

      1. Robert

        Not to mention the drought we suffered for most of that year. And curbs on lawn watering.

      True, but that was also a summer where the humidity was LOW most of the time…which I would take any day. LOL

    Always wonder how can do comparisons with past Houston weather history ie TV Weather, when so much weather history must be from Hobby.

    I’m an early morning runner, and this year seems exceptionally brutal from a dew point / humidity standpoint. Is this just my imagination?

    Whenever anyone mentions anything at all that happened in 2011, all I can think of is the heat and drought of that dreadful summer.
    Then again, the fact that I was working for weather forecasting company probably plays a part in that.

    I’m really curious about where the weather gathering site is located at Bush Intercontinental Airport. Is it in a green belt area? A heavily wooded area? I’m inside the loop in a residential neighborhood and my thermometer in the shade has certainly hit over 100 this summer.

    large pea size hail in Seabrook this evening, and I lost a big tree branch in the front yard.
