Recent forecasts from multiple models indicate overnight lows in Guangzhou on October 6 centering near 19–20 °C, driven by northerly flow and mostly clear skies that promote radiative cooling after daytime highs around 26–28 °C. Light winds of 5–10 km/h and dew points near 10–12 °C limit further temperature drops, while the absence of significant moisture or frontal systems keeps conditions stable. Historical October averages near 22 °C provide context for the current cooler pattern, though model spreads of 1–2 °C reflect typical uncertainty in minimum temperature predictions. Final resolution will depend on official station observations, with traders closely watching any last-minute adjustments to steering patterns or cloud cover.
