Current forecasts from meteorological models indicate a highest temperature in Guangzhou of 29–31°C on June 15, aligning with the market’s closely matched leading outcomes around 30°C. In this subtropical monsoon climate, typical early-summer conditions feature high humidity, frequent cloud cover, and scattered showers that limit daytime heating, keeping peaks near the June average of 31°C. Recent model runs show minor variations driven by the timing and intensity of precipitation, with clearer intervals potentially allowing brief rises toward 31–32°C while sustained rain favors the lower end of the range. Official guidance from agencies like the China Meteorological Administration emphasizes these uncertainties in short-range forecasts, which traders weigh against historical June maxima.
