**Trader consensus heavily favors a 16°C low in Shanghai on October 15, 2026, at 98.5% implied probability, reflecting consistent forecasts from official meteorological sources showing overnight temperatures bottoming near that threshold under overcast skies and light southeast winds.** Current observations place daytime highs around 23–25°C with gradual cooling after sunset, aligning with typical mid-October climatology for the region and model consensus from GFS data. Minimal precipitation risk and stable pressure support steady radiative cooling without sharp drops. A realistic challenge would require an unforecasted cold-air intrusion or revised station readings falling to 15°C or below, though recent model runs show low variability in the overnight minimum.
