Current atmospheric conditions over Beijing, including persistent cloud cover and light rain, are sharply limiting daytime solar heating and keeping maximum temperatures at or below 25°C, which explains the market’s near-certain consensus on that outcome. Official short-range forecasts from the World Meteorological Centre Beijing and supporting model runs confirm a cooler airmass advecting across North China, with surface observations showing suppressed insolation and enhanced evaporative cooling. Historical May climatology indicates daytime highs typically reach 26–28°C under clearer skies, so the present synoptic setup represents a clear departure. Only an unexpected rapid clearing of clouds combined with stronger southerly flow could push readings into the mid-20s or higher before the daily maximum is recorded, though such a shift remains unlikely given the locked-in moisture and stable boundary layer.
