Persistent southwest monsoon flow and a lingering low-pressure trough maintain cloudy, humid conditions with scattered showers over Hong Kong through June 17, suppressing nighttime radiative cooling and anchoring minimum temperatures near the June climatological average of 26–27 °C. Hong Kong Observatory guidance and multi-model consensus currently favor overnight lows of 25–26 °C, consistent with the tight 39 % / 38.5 % market split between those two outcomes. Subtle differences in cloud-cover duration, shower timing, and boundary-layer moisture will determine whether the thermometer bottoms at 25 °C or 26 °C; stronger or more persistent convection would favor the lower reading, while brief clearing could allow marginally greater cooling toward 27 °C. The above-normal seasonal temperature outlook reinforces limited downside risk below 24 °C absent an unexpected steering-pattern shift. Updated HKO briefings and next model runs remain the key near-term catalysts.
