**Clear skies and light northerly winds under stable high pressure have driven Paris temperatures to a peak of 27°C on September 23, 2026, aligning with National Weather Service and Météo-France observations of afternoon maxima near 27°C after morning lows around 15°C.** This outcome reflects typical late-September conditions under a building anticyclone, with minimal cloud cover allowing efficient daytime heating while preventing significant convective activity or cooling from precipitation. Historical September 23 averages hover near 20°C, but current synoptic patterns have produced conditions matching the upper end of recent analogs. Market-implied odds at 100% for exactly 27°C capture the tight clustering of official station readings around this value. Minor deviations could arise from microclimate differences between urban stations and airport references like Orly, or slight adjustments in final verified maxima, though late-day stabilization makes larger shifts 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=lfpb
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
