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.
