WeatherNormal

Average monthly weather and the best time to visit US cities, from NOAA Climate Normals.

WeatherNormal is a free, answer-first weather reference for 40 US cities. For each city you can look up average high and low temperatures, monthly precipitation and snowfall, and a data-driven best time to visit — all from the official NOAA 1991–2020 U.S. Climate Normals (public domain). Climate normals are 30-year averages, so they tell you what weather is typical, not a forecast.
