Official forecasts from the Hong Kong Observatory project a minimum temperature of 27°C on September 26, 2026, under persistent high-pressure conditions delivering mainly fine, dry, and very hot weather with light winds. This aligns with the market-implied odds favoring 26°C or 27°C, reflecting model consensus and recent observations showing overnight lows near seasonal norms of 25–27°C for late September. Stable subtropical ridge influence and sea surface temperatures around 29°C limit rapid cooling, while the absence of significant frontal systems or monsoon surges through the immediate period reinforces trader confidence in this narrow range ahead of resolution.
