Blue Skies and Spring Heat: Austin Swelters Under 87-Degree Highs Ahead of SXSW

A Record-Challenging Wednesday in the Capital City

Austin residents and early South by Southwest (SXSW) arrivals are waking up to an unseasonably warm Wednesday, March 11, 2026. As the city prepares for one of its busiest weeks of the year, the weather is taking center stage with temperatures climbing significantly higher than the typical March average. Today’s forecast calls for a high of 87°F, a sharp contrast to the usual mid-70s often seen during the early spring season.

Morning: A Balmy and Humid Start

The morning began with exceptionally mild conditions, as overnight lows only dipped to 71°F. Humidity levels are currently peaking near 80%, a common occurrence for Central Texas mornings, which may make the early hours feel slightly muggy. However, the heavy cloud cover seen earlier this week has largely cleared, leaving behind bright, hazy skies. For those heading out for early coffee runs or setting up event stages downtown, light layers are recommended, though you will likely be shedding them before the clock strikes noon.

Afternoon: Peak Heat and Fresh Breezes

By mid-afternoon, the mercury is expected to hit the daily peak of 87°F. While the sun will be out in full force, the day won't be entirely still. A fresh breeze is expected to sweep through the area, with average wind speeds of 12 knots and occasional gusts reaching up to 31 mph. These winds should provide some much-needed relief for those walking the South Congress or Red River districts. It is important to note that the UV index is rated as "Very High" (8) today, so sunscreen and hydration are essential for anyone spending extended periods outdoors.

Evening: Perfect Conditions for Live Music

As the sun sets, the temperature will gradually descend into the mid-70s, creating an ideal atmosphere for Austin’s nightlife. Several major events are taking advantage of the clear evening skies tonight:

• BMI Presents Howdy Texas: The annual showcase at Guero’s Taco Bar on South Congress kicks off this evening, featuring artists like Magna Carda and Claire Hinkle.
• Broadway in Austin: The theatrical production of "The Great Gatsby" continues its run at the Bass Concert Hall with a 7:30 PM performance.
• Late Night Vibe: Evening temperatures will remain comfortable for outdoor patios, eventually settling back toward 71°F near midnight.

Wind and Rain Outlook

There are currently no active rain warnings for today, and the chance of precipitation remains at zero percent. However, the dry spell won't last long. A cooling trend and potential rain are on the horizon for Thursday, March 12, with forecasts suggesting a drop in temperatures to the low 70s and approximately 0.11 inches of rainfall. For today, the primary concern remains the gusty winds, so be sure to secure any loose outdoor event signage or lightweight patio furniture.
