Trader consensus on Polymarket has locked in 21°C as the highest temperature at Ankara's Esenboğa International Airport station with 100% implied probability, driven by the Turkish State Meteorological Service (MGM)'s latest hourly forecasts showing a midday peak of 21°C under clear skies and low 26% humidity that maximizes solar heating. Current observations as of mid-afternoon register 20.8°C with light 4 km/h winds, aligning precisely with model projections and historical late-April patterns where daily maxima typically occur between 12:00–15:00 before evening cooling to 13°C. This positioning reflects high-confidence observational data over the past 24 hours, with climatological norms averaging 17–20°C. Realistic challenges would require an anomalous late-afternoon heat burst or measurement revision, both improbable given the cooling trajectory and stable high-pressure conditions; final Wunderground station data will confirm resolution by day's end.
