Trader consensus on Polymarket shows near-certainty (100% implied probability) for an 18°C high temperature in Shanghai on March 29, 2026, anchored by real-time observational data from the China Meteorological Administration's Shanghai Meteorological Observatory at Xujiahui and Shanghai Pudong International Airport stations, which recorded midday peaks precisely at 18°C amid partly cloudy skies, mild southerly winds around 10-15 km/h, and reduced solar insolation that capped warming potential. This aligns with recent China Meteorological Administration hourly reports confirming no higher readings as evening cools temperatures below 16°C. Realistic challenges are minimal but could include a rare post-sunset data revision from quality-controlled archives or an overlooked urban heat island effect at secondary stations; final daily summaries expected within 24 hours.
