Current forecasts from the National Weather Service and other models project a minimum temperature in Austin on September 30 in the mid- to upper 70s, driven by a warm, humid air mass with southerly winds, high dew points, and overnight cloud cover or scattered showers that limit radiational cooling. This setup favors outcomes near 76–77°F while keeping the probability of dropping to 69°F or below relatively low, as persistent moisture and light winds suppress typical overnight drops. Model consensus shows limited spread in the short term, though shifts in precipitation timing or wind patterns could alter the exact low by a few degrees before resolution. Historical September averages near 63°F highlight how late-summer conditions are elevating the floor this year.
