Traders see closely matched odds around 25–28°C for Hong Kong’s daily minimum on July 16 because mid-July climatology features high humidity and typical overnight lows near 26–27°C, with limited variation expected absent major weather shifts. Recent model runs show scattered showers and variable cloud cover that could modestly suppress nighttime temperatures toward 25°C or allow clearer skies to hold readings near 27–28°C. Steering flow from the subtropical ridge and any distant tropical activity remain key variables that could alter radiative cooling and boundary-layer moisture. With resolution just two days away, the narrow spread in market-implied probabilities reflects ongoing uncertainty in local forecast guidance and the modest historical day-to-day fluctuation in Hong Kong summer minima.
