Current National Weather Service and NOAA ensemble forecasts for New York City on August 5 center afternoon highs near 80–83°F, with the spread across model runs and limited afternoon mixing under modest onshore flow driving the tight clustering around the 80–81°F and 82–83°F outcomes. Sea-breeze influences from the Atlantic and variable boundary-layer moisture introduce the main uncertainty, preventing stronger consensus on whether peaks reach the upper end of that range or stay capped by coastal cooling. Historical August normals near 83°F at Central Park provide context, but the near-term model disagreement on diurnal heating and any residual cloud cover keeps lower-probability bins like 84–85°F viable only if mixing strengthens more than currently indicated.
