Official National Weather Service forecasts for Austin on October 13, 2026, center on highs in the mid-90s amid persistent southerly flow and high dew points near 75°F that support heat indices above 100°F. Model consensus from recent runs highlights partly cloudy conditions with limited mixing, keeping maximum temperatures clustered around 92–95°F rather than pushing into the upper 90s or cooling below 90°F. This aligns with the broader warm October pattern across South Texas ahead of a stronger cold front expected midweek, which has stabilized trader-implied probabilities heavily toward the 94–95°F bin at over 60% while assigning meaningful but secondary weight to 96–97°F.
