Highest temperature in Shenzhen on July 25?

Platform comparison

Market context

Shenzhen's weather on 25 July 2026 will be shaped by the South China monsoon system, which typically delivers peak summer heat to the Pearl River Delta region during late July. The city experiences its hottest conditions in this window, with afternoon temperatures regularly exceeding 33°C. Recent meteorological patterns through mid-2026 will establish the baseline for seasonal intensity, though no significant shifts have been reported in the last 48 hours that would materially alter expectations for this specific date.

Historical records from Shenzhen Bao'an International Airport Station show July temperatures clustering between 32–36°C on peak days, with occasional readings reaching 37°C during particularly intense heat waves. The 0% crowd probability suggests traders are either awaiting clearer forecast data or treating this as a calibration exercise given the distance to the settlement date. Comparable July days from the past five years provide the most reliable reference point, as they account for local urban heat island effects and airport microclimate conditions that differ from central Shenzhen readings.

The key variable traders should monitor is the positioning of the western Pacific subtropical high-pressure system in early July 2026, which determines whether monsoon moisture or drier continental air dominates the region. Tropical cyclone activity in the South China Sea during June and early July could also influence atmospheric circulation patterns. Wunderground historical data for Bao'an will be the sole settlement source, so familiarity with that station's recording methodology—particularly its sensor location and any maintenance schedules—matters for precise range selection.
