Houston starts Tuesday, October 27, under cloudy skies and mild air near 70 degrees, with the city headed for an afternoon high near 82. Rain is not the main character today, though low-end rain chances return Tuesday onward; temperatures should settle near 67 overnight.
The National Weather Service Houston/Galveston says low-end rain chances return Tuesday onward, while Hoodline's forecast puts Tuesday's rain chance at 0%. East winds should stay light, around 5 mph. Compared with Monday's earlier outlook, the updated forecast brings low-end rain chances back Tuesday onward and raises the odds toward the end of the week; Hoodline's earlier forecast had Tuesday looking drier.
Wednesday Stays Warm With A Few Showers Possible
Wednesday should reach about 83 degrees with partly sunny skies. A slight chance of showers arrives after 1 p.m., especially west of I-45, where forecasters expect the best odds for isolated rain or storms. Thursday then looks like the week's cleanest bet: mostly sunny, dry and in the low to mid 80s.
Halloween Weekend Brings The Better Rain Chance
Friday stays warm near 80, but a slight chance of afternoon showers returns. Saturday's Halloween forecast calls for a high near 83, with a 30% chance of showers and thunderstorms.
After that, Houston gets another warm reset: Sunday should be mostly sunny and near 85, with early next week looking mostly sunny and highs in the mid-to-upper 80s. Overnight lows stay mild, mostly in the mid-to-upper 60s, so outdoor plans look broadly workable—but anyone planning Halloween activities should keep a backup plan for a passing shower or storm.
No land-based watches or warnings are listed for the Houston area. For now, the practical forecast is simple: light layers for the warm days, and an umbrella or weather app check heading into Friday and Saturday.
