This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Paris-Le Bourget Airport Station in degrees Celsius on 13 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Paris-Le Bourget Airport Station, available here: https://www.wunderground.com/history/daily/fr/bonneuil-en-france/LFPB. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
Official forecasts from Météo-France and supporting models indicate a peak of 38°C in Paris on August 13 amid an ongoing heatwave, with a yellow alert active and urban heat island effects sustaining elevated readings. Afternoon temperatures are projected to reach this threshold under clear skies and southerly flow, aligning with recent model consensus that has held steady through the past 24–48 hours. Historical August baselines in the city average near 25–28°C, underscoring the anomalous intensity driving trader consensus toward 38°C at over 99% implied probability. Minor variations in exact measurement timing or localized microclimates could theoretically shift the official high, though current observations make such outcomes highly improbable before resolution.
