Forecast models indicate increasing cloud cover and showers on July 26, limiting solar heating and likely capping Shenzhen's daily maximum near 29–30 °C, which explains why these outcomes hold the highest market-implied odds. Recent days have featured clearer, sunnier conditions supporting highs of 31–34 °C, but the shift to overcast skies and precipitation reduces insolation while enhancing evaporative cooling. Subtropical humidity and typical July monsoon patterns further moderate peaks, though timing of any rain bands introduces forecast spread. Traders weigh National Meteorological Center guidance and ensemble runs showing modest cooling against the risk of breaks in cloud allowing brief warming toward 32 °C or higher. Updated model outputs and radar trends over the next 48 hours will refine resolution around these thresholds.
