Market context
Ankara has spent the past day on a cooler, unsettled track, with the latest city forecasts pointing to highs mostly in the low 20s Celsius rather than anything extreme. For Esenboğa Airport, that matters because the market resolves on the single highest reading recorded during the day, and a weak warm-up can still leave the top of the range short of the upper brackets. With the settlement window ending at noon UTC, the key question is whether morning heating is strong enough to lift the airport station into a higher band before temperatures level off.
The historical shape of May in Ankara supports the present 0% crowd view only loosely: the month is usually mild, with typical highs around the low 20s Celsius and overnight lows near 10°C, but late-May spikes do happen. Recent May forecasts for Ankara have shown daily highs in the mid-20s Celsius at the upper end, while climate summaries put the warmest days of the month below 25°C most years. In other words, an outcome in the higher temperature bands is possible, but it generally needs a clear, dry, sunny set-up rather than the more common mixed spring pattern.
Traders should watch the morning forecast updates for cloud cover, wind direction, and any shower timing around the airport. A shift to brighter conditions after sunrise would improve the chance of a stronger midday peak; lingering cloud or scattered rain would cap the day’s maximum. The relevant source is the Wunderground history page for Esenboğa Intl Airport, where the final recorded maximum is settled once the day is complete.

The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
