Current forecast models from the National Weather Service and other agencies point to an overnight low in New York City around 70–75°F for August 13, with the market’s closely clustered probabilities around 70–75°F reflecting modest uncertainty in exact minimum readings. Key differentiating factors include variable cloud cover that modulates radiative cooling rates, humidity levels influencing dew point suppression, light wind patterns limiting mixing, and the urban heat island effect that typically elevates city-center temperatures relative to surrounding areas. Normal August climatology features average lows near 70°F, and the absence of strong frontal systems or unusual steering patterns keeps outcomes tightly grouped while allowing small model revisions to shift implied probabilities ahead of the day’s official minimum observation.
