Official forecasts for Guangzhou on June 9 point to a maximum of 29–30°C under cloudy to overcast skies with scattered showers or thunderstorms, which explains the market’s strong clustering around those outcomes. Persistent cloud cover and precipitation limit solar heating in this subtropical monsoon environment, where typical early-June highs reach 31–33°C under clearer conditions. Recent model runs from regional agencies show minimal disagreement on steering patterns that favor onshore flow and moisture, keeping temperatures below recent peaks earlier in the month. Traders appear to weigh the resolution criteria—daily high measured at official stations—against these stable atmospheric conditions, with limited upside risk from unexpected clearing.
