Forecasts from sources including LUFT TIME, Worldmeteo, Met Office, and Chinese meteorological summaries project a high near 31–33°C for Guangzhou on September 5, aligning closely with the 1991–2020 climatological average of 32.7°C. Trader sentiment clusters around these values because ensemble model runs show modest spread driven by uncertainty in afternoon convective cloud cover and scattered showers, which can reduce peak solar heating by several degrees. Light winds and high humidity typical of the post-monsoon transition further limit extreme warming, while the low implied probabilities for 34°C or higher reflect the absence of strong subsidence or clear-sky conditions that historically enable records near 37°C. Updated model guidance expected within 24–48 hours will likely narrow resolution thresholds.
