Has Austin been warmer than normal lately?
2025 averaged 71.9°F, 1.9°F above the 1991-2020 normal of 70.0°F. 5 of the 5 complete years since 2021 ran warmer than the normal.

Which places near Austin share this climate record?
11 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
