Traders see the highest temperature in Paris on August 28 as tightly contested around 22–24°C because ensemble forecasts from ECMWF and Météo-France show a modest high-pressure ridge over northern France with light southerly flow, but small differences in cloud cover, boundary-layer mixing, and Atlantic moisture advection could shift the daily maximum by 1–2°C. Model runs remain sensitive to exact timing of any weak frontal passage or diurnal heating peaks, keeping probabilities clustered rather than favoring extremes. Historical late-August baselines for Paris average near 23°C, so current guidance aligns with typical late-summer conditions while underscoring the narrow uncertainty range typical two days before the event.

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.
