Trader consensus on Polymarket strongly favors a 22°C high temperature in Shanghai at 78.1% implied probability, driven by a recent warm spell exceeding late-March climatological norms of 15–18°C highs under neutral ENSO conditions. China Meteorological Administration's morning forecast for March 30 projects 19°C amid light rain and northwest winds of 16–24 km/h, following March 29's observed high near 16°C with ongoing showers; however, ensemble models and early observations suggest potential for brief clearing and higher peaks if cloud cover thins. Historical analogs show such spring surges possible, though precipitation risks capping intensity—hourly station data from official CMA monitors will confirm the peak before midnight local time.
