Recent forecasts for Guangzhou point to a daily maximum near 35–36°C on August 16 amid typical subtropical summer conditions of high humidity and scattered thunderstorms. Model guidance and local outlooks indicate passing showers that may limit full solar heating yet still allow afternoon peaks in the mid-30s, consistent with the market’s heavy weighting toward 35°C and 36°C. These probabilities reflect trader assessment of current atmospheric moisture and steering patterns that favor modest cooling relative to peak summer heat but fall short of stronger rain suppression. Historical August averages hover near 32–33°C, so the implied distribution captures the elevated baseline driven by recent regional warmth without crossing into extreme heat thresholds. Updated model runs and official briefings in the final hours before resolution remain the key variables that could shift sentiment.
