Latest National Weather Service guidance and ensemble model runs point to a highest temperature in New York City on July 28 likely falling in the upper 70s to low 80s Fahrenheit, with the spread reflecting modest uncertainty in afternoon cloud cover, timing of any showers, and boundary-layer mixing. July climatology for Central Park shows average daily highs near 84 °F, but a passing weak frontal boundary and higher dew points are expected to limit full insolation and cap peak readings. Model consensus clusters around 78–81 °F, while slight differences in simulated convective initiation or sea-breeze timing create the narrow probability bands traders are pricing. Updated short-range forecasts and hourly observations tomorrow morning will further refine the exact maximum before market resolution.
