Early September rainfall in New York City has totaled roughly 0.8 inches through the first five days, driven by initial showers that disrupted the U.S. Open, followed by a drier pattern with mostly sunny conditions and low precipitation probabilities through mid-month per National Weather Service forecasts. NOAA’s seasonal outlook favors above-normal totals for the Northeast, reflecting enhanced moisture transport and frontal activity, while current neutral-to-weak El Niño conditions may suppress Atlantic tropical cyclone tracks and associated extreme rainfall. These dynamics support the market’s tight clustering around 3–4 inches—near the 4.3-inch climatological average—with differentiation hinging on late-month steering patterns, precipitable water anomalies, and any unexpected coastal systems.

If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.
The resolution source for this market will be NOAA, specifically the figure for September 2026 when the "Monthly summarized data" for "Central Park NY" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=okx link once that figure is finalized for the whole month of September 2026.
If the relevant data is not available by December 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.
The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
