Trader consensus on Polymarket reflects tight uncertainty in Shenzhen's March 25 high temperature, with models clustering around 27-28°C amid subtropical spring warmth. Leading forecasts from ECMWF and GFS ensembles project daytime peaks of 26-30°C, driven by persistent high pressure and light southerly winds enhancing urban heat island effects in this densely built port city. Recent developments include a slight cooldown from earlier monsoon influences, but low cloud cover variability introduces divergence—clear skies could push toward 30°C+, while afternoon sea breezes favor 26-27°C. Historical March averages hover near 25°C, yet anthropogenic warming and El Niño residuals tilt odds higher, explaining the razor-thin market-implied probabilities differentiating these outcomes.
