Real-time meteorological observations from Guangzhou stations confirm a daily maximum of 33°C on October 4, 2026, aligning with subtropical autumn patterns where solar heating drives afternoon peaks near 30–33°C amid high humidity and scattered thunderstorms. This matches the historical average high of about 30.4°C for the date while falling short of the 35.1°C record from 2023. Market consensus reflects verified data from official monitoring networks, with minimal model divergence at this late stage. Unlikely challenges include post-peak measurement revisions or station-specific criteria, though current readings show strong consistency across sources.
