**Trader consensus has locked in 25°C at 100% implied probability for Guangzhou's highest temperature on April 30, driven by confirmed observational data from official meteorological stations, including Guangzhou Baiyun International Airport (ZGGG), reporting a midday peak of exactly 25°C amid persistent cloud cover, high humidity around 80-90%, and scattered showers that capped solar heating.** China Meteorological Administration records align with international sources like Weather Underground, showing no readings exceeding this threshold as evening approaches, consistent with short-range forecast models predicting subdued warming under a weak high-pressure ridge. This positioning reflects skin-in-the-game agreement on real-time measurements over prior expectations of 26-28°C averages for late April. Realistic challenges include late-reported data from remote stations revealing a higher outlier or post-day quality control revisions by the Guangzhou Central Meteorological Observatory, though such shifts are rare once daily maxima stabilize. Final resolution awaits the official daily summary.
