Current ensemble forecasts from the Hong Kong Observatory and global models indicate maximum temperatures on July 22 most likely in the low 30s°C, shaped by typical subtropical summer conditions including the influence of the Pacific high-pressure ridge, elevated sea surface temperatures, and variable monsoon moisture. Cloud cover, convective showers, and the urban heat island effect introduce key uncertainties that differentiate 31°C from 32°C outcomes, with limited model spread preventing stronger consensus on either side. Trader positioning around these closely matched probabilities reflects aggregated assessment of forecast revisions expected before resolution, consistent with July climatology where daily highs average near 32°C but often moderate under rain.
