- The period of record is January 1895 to December 2018. NJ State Climatologist New Jersey Geological & Water Survey

- All data are from the web page of the New Jersey State Climatologist. http://climate.rutgers.edu/stateclim/ [email protected]
- NOAA altered the way it estimates monthly statewisde precipitation and temperature. All years were reanalyzed using this procedure resulting in minor changes from previously reported http://www.njgeology.org/
