Recent National Weather Service and model guidance point to a highest temperature in Austin on October 3 in the upper 70s to low 80s, shaped by lingering tropical moisture from former Hurricane Polo that sustains cloud cover, scattered showers, and northeasterly flow. This pattern favors highs near 77–82°F while suppressing stronger daytime heating, consistent with trader consensus across the closely bunched 74–81°F bins. Official forecasts highlight moderate uncertainty from variable rainfall timing and model spread on cloud thickness, with NWS updates and new model runs expected to refine the outlook before resolution. Historical October averages near 82°F provide context, but current conditions tilt cooler.
