Highest temperature in Shanghai on August 3?

Platform comparison

Market context

Shanghai’s airport-temperature market is being priced as a near-certainty on the downside, with the crowd at 0% for a YES outcome despite mid-summer heat still being the default in the city. Forecasts around the date point to a hot, humid pattern rather than anything extreme: AccuWeather’s August view for Shanghai shows highs mostly in the low- to mid-30s Celsius, while a city forecast for 3 August calls for 35°C with showers and thunder. [1][2]

That is broadly consistent with Shanghai’s August climate, which is usually hot, sticky and often interrupted by rain, but not automatically enough to threaten the top end of the market’s range. Comparable August guides cluster around average highs near 31–32°C, yet also note occasional spikes into the mid-to-high 30s, including a cited 39°C peak on 24 August 2025. [12][14] The key point for traders is that the settlement source is Shanghai Pudong International Airport Station, so the final print depends on that specific microclimate and not the broader city forecast. [1]

The main catalysts are therefore the late updates from the airport-level forecast, any escalation in thunderstorm risk, and the day’s actual sequence of rain bands, since cloud and precipitation can cap the maximum even in a hot air mass. A recent official city forecast from Hong Kong’s observatory put Shanghai at 29–37°C with cloudy conditions, which underlines how high the ceiling remains if sun breaks through. [6] Traders should watch whether the airport station trends closer to the low 30s or whether a hotter, drier midday window develops before the settlement cut-off.
