Pronóstico: Highest temperature in Istanbul on July 9?

Platform comparison

Market context

The underlying event is the daily peak heat at Istanbul Airport on 9 July 2026, a date when Turkey’s driest, hottest month drives temperatures well above 30°C across most regions, with Istanbul’s long-term July average sitting at 27°C and 12 hours of daily sunshine. Historical data shows Istanbul rarely exceeds 30°C in early July, though extreme continental heat pushes peaks toward 26–27°C, making a 25°C outcome plausible but not dominant; the current 0% YES probability for 25°C likely reflects market overconfidence that heat will breach this threshold, given that comparable years show 27°C as the typical ceiling with low humidity [1][3].

Traders should monitor NOAA’s real-time “Temp” column updates for Istanbul Airport (site LTFM) on 9 July, as the first data point for that date will trigger resolution, and any sudden shift in Anatolian heat pressure could invalidate the 25°C bucket by pushing peaks to 26°C or higher [2]. Recent news from The Straits Times confirms Turkey’s national heat record hit 50.5°C in Silopi on 25 July, underscoring the intensity of 2026’s summer, but Istanbul’s coastal position usually moderates extremes, so the key dependency is whether a dry, high-pressure system stalls over the Aegean to amplify daytime highs beyond the 27°C average [7]. Watch for NOAA’s metric-unit table updates and any forecast revisions from AccuWeather indicating a spike above 84°F (29°C), which would directly drain probability from the 25°C outcome [9].

FAQ

Can I bet on individual matches?

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
