This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 24 Apr '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=LTFM To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve to "Yes" until 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.Trader consensus on Polymarket has locked in 18°C as the highest temperature in Istanbul on April 24, 2026, at virtually 100% implied probability, backed by official observations from Istanbul Airport (LTFM) METAR reports and NOAA-relayed data confirming a daytime maximum of 18°C under partly cloudy skies with light southerly winds. Turkish State Meteorological Service (MGM) daily summaries align, recording peaks in the 15–20°C range amid seasonal norms for late April, where historical highs average 16–17°C amid emerging spring warmth. This positioning reflects resolved uncertainty from pre-event forecasts predicting mild conditions below 20°C, with no significant deviations. Realistic challenges would require post-measurement revisions from MGM or supplemental station data showing a higher peak, though such adjustments are rare once validated.
