Current ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System converge on a daily maximum of 27°C in Shanghai under persistent high-pressure ridging that drives subsidence warming and light southerly flow. This stable pattern, with minimal cloud cover and no significant frontal systems, aligns precisely with the market-implied probability exceeding 99 percent for the 27°C bin. Mid-May climatological normals near 24–25°C provide useful historical context, yet the current synoptic setup supports a modest above-average reading without exceeding the next threshold. Traders are monitoring the final Shanghai Meteorological Service updates and official observations from Pudong International Airport, where any unexpected increase in moisture or wind shift could realistically push the peak to 28°C or higher.
