Recent National Weather Service guidance and ensemble model consensus point to a highest temperature in the low 70s for New York City on September 29, driven by northwest flow behind a departing coastal system that delivered heavy rain and strong winds on the 27th and 28th. Clearing skies and light northwest winds of 5–10 mph should allow modest daytime heating under partly to mostly cloudy conditions, with dew points in the upper 50s limiting humidity-related moderation. Historical late-September baselines for Central Park average near 72°F, though forecast spread across runs creates the tight market clustering between 70–73°F bins. Updated model guidance and the next NWS forecast discussion remain the key near-term catalysts.
