Forecasts from major models indicate an afternoon peak near 28–29°C in Paris on August 27, 2026, driven by southerly flow advecting warmer air under partly to mostly cloudy skies with scattered showers or thunderstorms. This exceeds the 1991–2020 climatological average high of 24.3°C, reflecting seasonal warmth tempered by high humidity and convective cloud cover that limits strong solar heating. Model spreads arise mainly from timing and intensity of precipitation, which could suppress the maximum by several degrees or allow brief spikes above 29°C if breaks occur. Traders weigh these variables against real-time observations, producing closely matched implied probabilities for 27–29°C outcomes while assigning lower odds to 30°C+ given the unstable air mass.

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=lfpb
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.
