This PredictPedia market is a Polymarket event titled "Lowest temperature in Munich on October 21?" It asks which temperature range will contain the lowest temperature recorded at the Munich Airport Station on 21 October 2026, measured in degrees Celsius [1]. The event is grouped under the climate category and is a set of separate temperature brackets rather than a single yes or no question [1]. The brackets in the saved sample run from a bracket for 1°C or below, through single-degree brackets from 2°C to 10°C, to a bracket for 11°C or higher [1]. The resolution source is NOAA. The rules name the lowest reading under the "Temp" column for all times on the observation day, from NOAA's Munich Airport time series [1]. Temperatures are resolved to whole degrees Celsius, so a reading such as 9°C is the level of precision used for settlement [1]. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day after that date, the rules switch to the Weather Underground Daily Observations table [1]. If no usable data exists for the observation date by that same deadline, the market resolves to the lowest bracket [1]. The timing rules are the main thing to understand. The market resolves 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 after the observation date, whichever comes first [1]. The rules also allow revisions to temperatures recorded within the market's timeframe until the first data point for the following date has been published [1]. The provider's listed end time for the event is 2026-10-21T12:00:00Z, but that field is a listing value and should be read alongside the resolution wording rather than treated as the moment settlement occurs [1]. The rules also cover erroneous data. If the resolution source publishes data that is clearly erroneous because of technical or operational error, or because of unauthorized interference, the market may stay open for up to seven calendar days (ET) from the original release while a correction is awaited [1]. If a corrected value is published in that window, that value is eligible for resolution. If not, Polymarket may issue a clarification on whether the original value can be used or whether other action is needed [1]. The Munich location itself is described in background sources. Munich is the capital and most populous city of the German state of Bavaria, and it sits on the river Isar north of the Alps [2]. That background explains the place, but it does not describe the station's historical readings or the expected weather for the date in question.
