Trader consensus clusters tightly around 24-27°C for Shenzhen's March 21 high, driven by ensemble weather model means from ECMWF and GFS projecting 25-26°C amid persistent southerly winds advecting subtropical warmth. Recent developments include a departed cold front yesterday, allowing insolation-driven diurnal peaks, with yesterday's observed 23°C as baseline. Differentiating factors hinge on afternoon cloud cover uncertainty: clearer skies enhance solar heating to favor 26-28°C via reduced albedo, while stratus caps at 24°C by limiting shortwave radiation. Shenzhen's urban heat island boosts highs 1-2°C above rural norms, aligning with historical March 21 averages of 25°C; watch CMA's 12Z update for shifts.
