Latest forecast models from agencies including the China Meteorological Administration and international services indicate Shanghai's overnight low on June 16 will likely settle at 22–23°C, driving the near-even market split between those outcomes. Persistent cloud cover and elevated humidity during the early Meiyu (plum rain) season suppress radiative cooling, keeping minimum temperatures aligned with seasonal baselines of 20–23°C rather than allowing deeper drops. Steadily rising regional temperatures and light easterly flow add modest warmth, while model consensus shows limited divergence ahead of resolution. Final official station readings will determine the exact value amid typical early-summer variability.
