Will the maximum temperature be >91° on Aug 19, 2026?

How this settles

Resolves YES if the maximum daily temperature recorded at Boston station CLIBOS by The Weather Company meets the contract's specific threshold condition (between a range, strictly greater than, or strictly less than the threshold) for the designated date.

• Strict vs. inclusive comparison varies by variant — The 'between 74–75°F' variant is inclusive of both endpoints, the 'greater than 86°F' variant is strictly exclusive (exactly 86°F resolves NO), and the 'less than 74°F' variant is strictly exclusive (exactly 74°F resolves NO) — the operator type differs across contracts in this series and must be checked carefully.
• Sole data source: The Weather Company / CLIBOS only — Only The Weather Company's reading at station CLIBOS governs resolution; NWS, Weather Underground, or any other source showing a different temperature is irrelevant, even if widely reported.
• Integer/whole-degree recording — no rounding specified — If The Weather Company records temperatures as whole-number integers, a reading of e.g. 86.4°F could be stored as 86°F and resolve NO on a 'greater than 86°F' contract; traders should confirm how fractional degrees are handled or displayed.

These are the rules for the whole series — every contract in it settles the same way. Full KXHIGHTBOS settlement rules →
