Current forecasts for Chengdu on August 21, 2026, center on a daily maximum near 32–33°C, driven by typical late-summer subtropical high pressure, elevated humidity from the Sichuan Basin’s topography, and variable cloud cover or scattered showers that can limit peak insolation. Official model runs show afternoon temperatures sensitive to timing of any convective activity, with clearer skies potentially allowing brief spikes toward 34°C while rain-cooled air or thicker cloud decks cap readings at 31°C or below. Historical August averages hover around 30–32°C, and the tight clustering of market-implied odds around these values reflects trader assessment of modest day-to-day variability in steering patterns and moisture without strong signals for extreme heat or widespread cooling. Updated numerical weather prediction guidance expected in the next 24–48 hours will likely refine these probabilities.
