Trader consensus overwhelmingly favors a 21°C high in Shanghai today, driven by the China Meteorological Administration's (CMA) latest forecast ensemble, which projects a precise daytime maximum under partly cloudy skies, light southerly winds, and moderate humidity inhibiting further warming. Morning observations from official stations align closely with model runs, showing temperatures climbing steadily but plateauing below 22°C amid typical late-March climatological patterns—historical averages hover around 13–15°C, with this mild ridge providing the boost. Unforeseen scenarios like prolonged clear skies enhancing solar insolation or urban heat island effects at specific measurement sites could push toward 22°C, though low-level cloud persistence and evening cooldown make this unlikely; final CMA observations by midnight will resolve the market.
