**Forecast models from sources like the China Meteorological Administration and international ensembles point to a minimum temperature near 26–27°C in Shenzhen on September 27 under partly cloudy skies and light southerly winds, with highs around 32–34°C and limited nocturnal radiative cooling due to high humidity and cloud cover.** Trader positioning, however, assigns notable implied probability to cooler thresholds such as 22°C or below, reflecting awareness of short-term model spread in subtropical boundary-layer conditions, potential for localized clear-sky pockets, or subtle shifts in steering patterns that could enhance overnight cooling. With only two days until resolution and stable large-scale synoptic setup, upcoming hourly updates from regional observatories will likely tighten consensus around the observed nocturnal minimum.
