National Weather Service observations at LaGuardia Airport (KLGA), the official resolution station for New York City temperature markets, recorded a maximum of 86°F on April 16, 2026, driving the market-implied 100% probability for the 86-87°F bin as traders align with verified meteorological data. This followed a record-shattering 90°F high in Central Park the prior day—surpassing the 1941 mark of 87°F—amid a persistent high-pressure ridge and warm southerly flow that elevated temperatures well above the April climatological average of around 62°F. Model forecasts from NOAA had anticipated continued warmth but with slight cooling, matching the outcome closely. While data revisions from equipment audits are exceedingly rare post-verification, any confirmed sensor anomalies could theoretically prompt a recount, though current evidence solidifies this positioning. Final monthly climate summaries from the NWS are expected soon.
