Official National Weather Service observations from Central Park and other NYC stations recorded a daily maximum temperature of 61–62°F on September 26, 2026, under persistent northerly flow, widespread rain, and breezy conditions that suppressed afternoon warming below seasonal normals of 72–73°F. Preliminary climatological reports issued the following day locked in this reading through standardized instrumentation and quality-controlled data, aligning precisely with the 62–63°F market bin and driving near-certain trader consensus. Any realistic shift would require post-verification corrections from the National Weather Service or adoption of an alternate station reading outside the observed range, though such revisions remain rare for temperature maxima once preliminary data are released.
