A dataset containing daily average temperatures of New York and San Francisco in 2021 as recorded by the US National Weather Service (NWS) at weather.gov.
Format
A data frame (specifically a tbl_df) with 730 rows and 3 variables:
cityNew YorkorSan FranciscodateDate in
YYYY-MM-DDformatavgAverage temperature in degrees Fahrenheit (°F) rounded to the nearest half degree
Details
It is difficult to pull data from the NWS. It does not provide the data via an API and the data it returns through its point-and-click interface isn't in plain text format! To make matters worse, you can only retrieve data from a city one month at a time.
For San Francisco, visit https://www.weather.gov/wrh/climate?wfo=mtr and choose "San Francisco City, CA", "Daily data for a month", and a month from 2021; for New York, visit https://www.weather.gov/wrh/climate?wfo=okx and choose "NY-Central Park Area", "Daily data for a month", and a month from 2021. Copy and paste the data into spreadsheet software for further processing.
