Current forecasts from the China Meteorological Administration show Shenzhen's maximum temperature on May 16 likely falling between 26°C and 28°C, with ensemble models indicating roughly equal chances across that narrow range due to variable cloud cover and light southerly winds. Subtropical spring conditions, including moderate humidity and the early influence of the East Asian monsoon, limit daytime heating while preventing sharp cooling overnight. Historical May averages near 27°C provide a baseline, yet small shifts in incoming solar radiation or urban heat island effects can tip the daily high by 1–2°C. Traders appear to price this uncertainty directly, as later model updates or afternoon observations could still nudge the final reading toward either boundary before resolution.
