For the first time in 380 days, Houston officially hit 101° on Thursday afternoon. Since 1980, we have averaged about 3 to 4 days this hot per year. Another interesting nugget about Thursday: With a high temperature of 101°, a low temperature of 81°, and a daily average temperature of 91°, it was Houston’s hottest day since August of 2016.
By far the most impressive statistic came from Galveston on Thursday. The temperature never dropped below 86°, meaning Thursday saw the warmest minimum temperature ever recorded in Galveston, with records dating back to 1874.

Since 2015, Galveston has set or tied 90 warm daily minimum temperature records, or near 25 percent of all of them. In just five years! This is consistent with what has happened elsewhere along the immediate Gulf Coast. New Orleans has set or tied warm minimum temperatures 120 times since 2015, while Tampa has done it over 130 times. Corpus Christi has has new warm minimum records over 50 times since 2015. This likely speaks to a combination of a fairly warm Gulf of Mexico in recent years and is also a symptom consistent with what is expected due to climate change. Galveston will likely match or exceed several more daily warm minimum temperature records before summer is over.
Today through Sunday
It’s going to be oppressively hot and humid again today. High temperatures will hit the mid-90s at the coast and upper-90s or 100° inland. Heat index values will again likely be at least 105° to 110°, with several locations likely to push even higher.

Galveston maxed out with a heat index value of 117° on Thursday afternoon. We may not be quite that absurd today, but it will come close.
Saturday and Sunday sees high pressure anchor itself over the state of Texas. This will keep the heat rolling on with more of the same: At least mid- to upper-90s for highs, with 100° or higher possible. Nighttimes won’t see temperatures drop below the upper-70s or low-80s. Humidity and heat index values may drop off just a bit on both weekend days as that drier high pressure sits overhead. If you’re looking for rain, you won’t find it here.
