Highest temperature in Shenzhen on July 28?

Platform comparison

Market context

Shenzhen's weather on 28 July 2026 will be shaped by the tail end of the East Asian summer monsoon, with the Pearl River Delta typically experiencing peak heat and humidity during late July. The 0% crowd probability suggests traders are either uncertain about the specific temperature bands available or treating this as a straightforward seasonal forecast rather than an outlier event. Recent 24-48 hour shifts in atmospheric patterns across southern China have been modest; the region remains locked into its standard late-July thermal regime with little indication of unusual heat waves or cooling systems approaching that date.

Historical records from Shenzhen Bao'an International Airport show July highs consistently ranging between 32–35°C, with extremes occasionally touching 36–37°C during particularly intense heat episodes. The 2015 heatwave pushed temperatures to 37.4°C on 13 July, whilst more typical late-month peaks settle around 33–34°C. Current seasonal models and monsoon forecasts suggest July 2026 will track near the 30-year average rather than deviate significantly, making mid-range temperature bands statistically more probable than outlier scenarios.

Traders should monitor updates from the China Meteorological Administration and regional weather services as the date approaches, particularly any advisories regarding tropical systems or upper-level pressure patterns that could alter the standard late-July profile. The settlement window closes at midday UTC on 28 July, leaving only the morning observation window at Bao'an to determine the final reading. Current atmospheric indices show no exceptional forcing mechanisms that would push temperatures substantially above or below the historical July norm.
