Hong Kong Observatory's latest multi-model forecasts and observational data position 29°C as the leading outcome at 49.5% market-implied probability for tomorrow's highest temperature, driven by a persistent high-pressure ridge bringing mainly sunny skies and light winds after recent showers cleared earlier this week. Current readings on April 16 show midday temperatures already reaching 27°C with low humidity around 70%, aligning with above-normal seasonal trends for April—where historical highs average 26°C but recent days like April 14 hit 29°C. The 28°C outcome at 28% reflects model uncertainty in peak afternoon heating, while 30°C or higher at 12.5% accounts for potential solar insolation boosts under clear conditions. Traders await HKO's evening update and tomorrow's hourly observations for final confirmation, as small shifts in cloud cover could tip the balance.
