Highest temperature in Istanbul on July 9?

Platform comparison

Market context

The real-world event driving this market is the peak daytime temperature recorded at Istanbul Airport on 9 July 2026, measured in degrees Celsius by NOAA. Current crowd-implied probability sits at 0% for a "YES" resolution, suggesting traders believe the temperature will fall outside the specific range being bet on, likely because historical averages and recent forecasts point to conditions that are warm but not extreme enough to hit that threshold.

Historical data frames this probability clearly: long-term averages for Istanbul in July show daytime maximums of 27°C with low heat and humidity, while the first ten days of the month typically average 27.2°C [2][6]. Even during intense heatwaves sweeping Turkey, where national records reached 50.5°C in the south-east, Istanbul rarely exceeds 30°C in early July [1][9]. The 0% probability aligns with these patterns, as the city’s climate in early July is characterised by consistent warmth rather than the extreme spikes required to resolve a "YES" in a high-threshold range.

Traders should monitor NOAA’s daily updates for the Istanbul Airport site, specifically the "Temp" column values released after the first data point for 9 July becomes public [1]. While AccuWeather forecasts July highs between 78°F and 91°F (25.6°C–32.8°C), the 0% probability suggests the market expects temperatures to stay below the critical range, possibly due to the region’s typical low humidity and moderate coastal influence [5]. No major weather announcements are pending, but the settlement window ending 12:00 UTC on 9 July means traders must act before the final NOAA reading is confirmed [1].
