Latest Météo-France guidance and ECMWF ensemble forecasts converge on a Paris high temperature of 18–19°C on May 10, driving trader consensus with 18°C at 42.5% implied probability, closely trailed by 17°C (22.9%) and 19°C (18.5%). This positioning reflects a weakening high-pressure ridge over Western Europe, shifting to cooler northerly flows after earlier weekly highs of 22–25°C amid variable spring patterns, aligning closely with the mid-May climatological average of 18.3°C at Paris-Montsouris station. Narrow ensemble spreads indicate low uncertainty, with minimal convective shower risk to disrupt diurnal heating, though boundary-layer conditions add slight variability. Fresh model runs overnight and official Météo-France hourly observations will refine probabilities ahead of resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Paris-Le Bourget Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
