Pre-Summer Heat Arrives in Houston: First 90-Degree Days Possible This Weekend
Houston is experiencing the arrival of pre-summer conditions this weekend, with temperatures climbing toward the 90-degree mark for the first time in 2026. According to Space City Weather, the city is firmly ramping into pre-summer, bringing several chances for highs in the upper 80s to near 90 degrees between Saturday and Tuesday.
The National Oceanic and Atmospheric Administration (NOAA) reports that over the last 10 days, most of the Houston area has received between 1 and 5 inches of rainfall, significantly improving soil moisture levels that had previously lagged for this time of year. While the rain has helped, the region is now transitioning into a warmer, more humid pattern typical of late spring.
Today, Houston faces a marginal risk (level 1/5) for severe storms, with isolated pop-up thunderstorms possible later this afternoon, primarily north of I-10 and east of I-45. Most areas are expected to remain dry, with highs in the mid to upper 80s. Additional scattered storms may develop late tonight in Louisiana and drift southward, potentially affecting areas east of I-45 near Lufkin and Beaumont, though likely missing the Houston metro.
The weekend outlook calls for mostly dry conditions, though an isolated shower or rogue thunderstorm cannot be completely ruled out. Expect spring-like humidity with south winds at 10 to 15 mph, and higher gusts over 20 mph possible in open areas or on hill crests — conditions relevant to participants in events like the MS 150 ride.
Monday and Tuesday are forecast to be the hottest days of the period, with the best chance of reaching the first official 90-degree high of 2026. Historically, Houston’s average first 90° day occurs around May 6, with the earliest recorded on February 20, 1986, and the latest on June 15.
As pre-summer settles in, residents should prepare for increasing heat and humidity, stay hydrated during outdoor activities, and remain aware of fluctuating storm chances through the early part of next week.
