This market will resolve based on the lowest 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 lowest temperature recorded at the Paris-Le Bourget Airport Station in degrees Celsius on 16 Aug '26. The resolution source for this market will be information from Wunderground, specifically the lowest 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.
Recent forecasts from meteorological models indicate overnight lows in Paris on August 16 will likely settle near 19°C, driving the market's leading implied probability of 39.5% for that exact minimum. Partly cloudy conditions and a moderating Atlantic air mass are limiting radiative cooling after daytime highs around 29°C, consistent with seasonal baselines where August lows average 15–18°C. Earlier heat buildup earlier in the week has slightly elevated nighttime readings, while ensemble guidance shows limited divergence on minimum thresholds. Updated model runs overnight will refine wind patterns and cloud cover that determine whether temperatures dip to 18°C or hold at 20°C.
