Recent meteorological observations from the Hong Kong Observatory confirm a minimum air temperature of 25°C on May 15, driven by a stable subtropical high-pressure ridge that suppressed cooler northerly flows and maintained typical early-summer conditions. Climatological baselines for mid-May show average overnight lows near 24–26°C, with this reading falling squarely within normal seasonal variability and consistent with reanalysis data from global models. The market’s near-certain outcome reflects the absence of any cold-front intrusion or anomalous radiative cooling that could produce lower readings. A realistic shift would require unexpected post-frontal clearing or measurement revisions at official stations, though current forecast verification indicates low likelihood of such changes before final data release.
