Trader consensus on Polymarket heavily favors a NYC high temperature of 60-61°F (30.5% implied probability) or 58-59°F (24.5%), reflecting the latest National Weather Service forecast pinpointing 59-62°F amid a strengthening upper-level ridge ushering mild southerly flow into the Northeast. Ensemble models like GFS and ECMWF show a tight spread, with deterministic runs peaking at 60°F during afternoon hours under partly cloudy skies and light winds minimizing mixing. Differentiating these bins hinges on subtle variations in boundary layer warmth—1-2°F swings from cloud cover timing or urban heat island enhancement—against March climatology averaging 52°F but trending warmer in recent El Niño-influenced springs. Key watch: 18z model updates could shift odds if cold front accelerates.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the LaGuardia Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ny/new-york-city/KLGA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
