Latest China Meteorological Administration forecasts and global ensemble models like GFS and ECMWF indicate Beijing's highest temperature on May 1 clustering around 26-28°C under partly cloudy skies with light southerly winds, fueling tight trader sentiment with 27°C at 38% implied probability and 28°C at 34%. This positioning stems from April's recent warming trend—yesterday's high of 24.4°C and today's projected 28°C—transitioning into early May's typical spring highs averaging 25-27°C, though model spreads reflect uncertainty in cloud cover thickness and wind persistence that could cap or boost peaks by 1-2°C. Key differentiators include ECMWF's drier outlook favoring 28°C versus GFS ensembles leaning cooler at 26°C; watch for CMA's evening update and station observations resolving the market.
