Highest temperature in Istanbul on July 22?

Platform comparison

Market context

The key event is the day’s **highest temperature at Istanbul Airport**, as recorded by NOAA in Celsius, and the market settles on the range containing that peak reading once the final 22 July observations are complete. With the book currently pricing **31°C** as the clear frontrunner and **32°C** as the main alternative, the implied distribution is already tightly clustered rather than spread across a wide heat range.[1]

For context, Istanbul’s July climate usually sits around a daily high of about **29°C**, so a print in the low 30s is not exceptional for midsummer, but it is warm enough that small forecast revisions matter for range markets like this.[2] The current crowd-implied **0% YES** for the market title likely reflects wording or settlement mechanics rather than a view that warmth is impossible; the more relevant question is whether the terminal NOAA series confirms a maximum inside the expected bucket once the next day’s first data point is published.[1]

For traders, the main catalysts are the near-term weather path, the timing of the final airport observations, and any late-day adjustment in the model consensus that shifts the peak by a degree. Book depth in this sort of contract is often driven less by the weather itself than by funding frictions: low-fee deposits, fast withdrawals, and easy on-ramps such as **Klarna**, **SEPA**, or **USDC** can widen participation and improve liquidity, while slower rails tend to keep positions smaller and spreads wider.
