Trader consensus points overwhelmingly to a 23°C low in Hong Kong on May 16, driven by the Hong Kong Observatory’s latest forecast models showing stable subtropical high pressure and light southerly flow that suppress overnight cooling. Current surface observations and ensemble guidance indicate minimum temperatures will settle near this value under clear to partly cloudy skies, consistent with typical May climatology for the region. The 0.1% odds on all other thresholds reflect the narrow uncertainty range once the diurnal cycle begins, as rapid changes would require an unforecasted cold surge or major model error. Key resolution data from official automatic weather stations will finalize the outcome by midnight local time, leaving little room for deviation under present atmospheric conditions.
