Forecasts from the Shanghai Meteorological Bureau and international models converge on a daily maximum of 32°C for August 27, 2026, under partly cloudy skies with light northeast winds and possible scattered showers that limit further warming. This aligns with late-August climatology for the region, where subtropical highs typically reach 31–33°C amid high humidity. Real-time observations midday have approached but not exceeded this threshold, reinforcing trader consensus behind the 99.9% market-implied odds. Only an unanticipated surge in convective cooling or a sharp revision in official station readings could shift the outcome, though model agreement and proximity to resolution make such deviations improbable.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zspd
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
