Cloud cover and scattered rainfall expected across the Pearl River Delta on June 15 are the main drivers keeping trader focus on the 29–30°C outcomes, which together command over 65% implied probability. Official forecasts indicate a mostly cloudy day with daytime maxima limited by reduced solar radiation and evaporative cooling, consistent with early East Asian monsoon patterns that typically hold Guangzhou highs near the 30–31°C climatological average for mid-June. Recent model consensus shows limited afternoon clearing potential, while urban heat-island effects and weak southerly flow offer only modest upward support. Any late-day breaks in the overcast could push readings to 31°C, though sustained precipitation would favor the lower end of the distribution.
