**Trader consensus heavily favors a 21°C low for Guangzhou on October 7, 2026, at 95.5% implied probability.** Current forecasts from multiple meteorological sources indicate clear to partly cloudy skies overnight under light northeasterly winds, with minimum temperatures expected to settle between 19–23°C. This aligns with the subtropical autumn climatology for the region, where the long-term average low for the date is approximately 22°C and recent days have shown gradual cooling from higher values earlier in the month. No active cold fronts, significant cloud cover, or precipitation are projected to alter radiative cooling rates substantially. Realistic challenges to this positioning would require an unexpected surge in northerly flow or denser low-level cloud that suppresses overnight temperature drops, though model consensus and current observations make such shifts improbable before resolution.
