Overview
Use the National Weather Service forecast rather than monthly averages for final packing and daily decisions. In warm weather, schedule outdoor stops earlier, carry water and use air-conditioned breaks. In winter, allow extra travel time and wear footwear suited to wet or icy pavements. Weather alerts should override a fixed itinerary, particularly for families and travellers with health or mobility needs.
The National Weather Service office serving New York issues watches, warnings and advisories for hazards such as extreme heat, severe thunderstorms, flooding, winter storms and strong coastal winds. These short-range alerts describe conditions that broad monthly climate averages cannot capture, especially where underground transit, exposed bridges, airports and waterfront districts respond differently to the same system.
