Recent official temperature observations from Shenzhen meteorological stations, following China Meteorological Administration protocols, have confirmed a daily maximum of at least 31°C on May 20, establishing the primary driver behind the market's complete consensus on the 31°C-or-higher outcome. This reading aligns with typical late-spring warming patterns in the region, where subtropical high-pressure systems and southerly flows often produce afternoon peaks in the low 30s Celsius. Model guidance from regional forecasts showed strong agreement on these conditions days earlier, with minimal divergence in predicted highs. While post-event data audits by official agencies remain possible, historical revisions to certified daily maxima are exceedingly rare and would require documented measurement discrepancies to alter the outcome.
