Official National Weather Service measurements from New York’s Central Park station recorded 5.31 inches of precipitation for September 2026, exceeding the 1991–2020 normal of 4.31 inches and landing squarely in the 5–6 inch range. This total, confirmed in the October 1 climate summary, reflects above-average rainfall including a late-month nor’easter that delivered over 1.5 inches in 24 hours around September 26–27, alongside scattered earlier events. Trader consensus at 100% on 5–6 inches aligns with these verified observations from the primary Central Park gauge. Only substantial post-summary revisions to the official tally or use of an alternate station with markedly different readings could realistically shift the outcome.
