Surface weather, by station and date
What the weather actually was, at nearly three thousand automated stations across the United States, on any day they were recording. Hour by hour, plus the same calendar date in every year on record. The longest records begin in the 1930s.

What is here
- Hourly
- Temperature, dew point, relative humidity, apparent temperature, wind speed and direction, gusts, pressure, visibility, cloud ceiling, hourly precipitation and the reported weather, as a chart and as a table, in the station’s own local time.
- Daily
- The official high, low and mean temperature, precipitation, snowfall and snow depth, peak gust, mean wind, and the phenomena observed that day: thunder, hail, fog, freezing rain, blowing snow, damaging wind.
- Every year
- That calendar date in every year the station recorded it, with the record high and low for the date, the 1991–2020 normal, the all-years mean, and where your date ranks.
- And the radar
- For dates from 1991, a link into the Level II archive at the nearest WSR-88D: the storm itself, next to the numbers it produced.
Common questions
How far back does this go?
It depends on the station. The longest airport records here begin in the 1930s and 1940s; most were in place by the 1970s. Each station states its own first and last day, and asking for a date outside that range says so rather than showing an empty table.
Are these measurements or estimates?
Measurements. Every value is a reading an instrument filed at a named place and a stated minute. Nothing here is modelled, interpolated or reconstructed, and readings that failed NOAA’s own quality checks are discarded rather than shown, which is why an occasional day is blank where the days either side of it are not.
Why is the hourly record thinner than the daily one?
They come from different archives kept for different purposes. A station can have a complete daily climate summary from the 1940s and hourly observations only from the 1970s, because the daily figures were transcribed from paper records and the hourly ones were not.
What time zone are the times in?
The station’s own local time, including the correct offset for that date. A day in January is read on standard time and a day in July on daylight time, as they were lived.
