Current short-range forecasts from multiple meteorological models indicate Shenzhen's minimum temperature on August 28 will likely fall in the 26–29°C range, driven by persistent cloud cover, scattered showers, and high humidity typical of subtropical late-summer conditions in the region. These factors limit daytime heating and keep overnight lows elevated compared to drier periods, consistent with historical August baselines near 25–27°C. The evenly matched 50% market-implied odds across thresholds reflect genuine uncertainty in the precise overnight minimum, as small shifts in steering winds, precipitation timing, or model consensus could push the low across key boundaries. Updated runs from agencies like the China Meteorological Administration over the next 48 hours will likely tighten the range ahead of resolution.
