Recent forecasts from meteorological agencies point to mild autumn conditions in Beijing on October 3, with daytime highs likely between 21–24°C amid possible light rain or drizzle early in the period followed by strengthening northerly winds. These factors create the narrow spread in market-implied odds across 19–26°C, as traders weigh model outputs on cloud cover, precipitation timing, and wind-driven cooling that can suppress peak readings by 1–3°C relative to clear, calm scenarios. Official guidance notes a 3–4 level northerly breeze later in the day, which may limit afternoon warming while historical October averages near 19–22°C provide baseline context. Updated model runs and surface observations over the next 48 hours will refine resolution thresholds.
