Recent forecast models from agencies like the China Meteorological Administration indicate a daily high near 29°C in Wuhan on May 22, with thundery showers possible under moderate southerly flow that could limit peak heating through cloud cover and evaporative cooling. This positions the 29°C outcome as the narrow leader in trader consensus, while the close probabilities for 28°C and 30°C reflect lingering uncertainty in how convective activity and boundary-layer moisture will influence the afternoon maximum. Historical May climatology shows typical highs of 26–28°C with standard deviations of 2–3°C, underscoring why small shifts in model guidance on timing or intensity of precipitation could readily tip the market between these adjacent thresholds.
