The condition is on the daily high at station KBOS over its local calendar day 2026-09-26 — local midnight to local midnight, daylight saving applied. It settles on the station's own record from the oracle: the extreme over the METAR observations received in the window, with the observation that produced it and its raw text. Met → YES pays, not met → NO pays. A day with a gap over six hours between observations or fewer than twelve observations is withheld: every position refunded at cost. Trading runs until the local day ends.
The station and its NOAA page are linked above. The official NWS value comes from the 1-minute ASOS record and can differ from the METAR extreme by about a degree. Settlement rules →
