Current forecasts from the Hong Kong Observatory and major numerical weather models indicate a minimum temperature of 23°C for May 17, driven by persistent warm, humid maritime air under a typical early-summer pattern with easterly flow and limited nocturnal cooling. This aligns with May climatology, where average overnight lows reach 24°C amid rising sea-surface temperatures and weak pressure gradients that suppress cold advection. Trader consensus at 96.4% for 23°C reflects the tight clustering of ensemble runs showing little variability in boundary-layer conditions. A realistic challenge would require an unexpected late-season cold surge or stronger-than-forecast northerly winds, though such events become statistically rare after mid-May and would need rapid model updates to shift odds.
