       Important Notes:

• The source of the historical data here is the NCDC GSOD (updated through 2024 as of 13 August 2025).
• The records are defined here using GMT, with the day resetting at 00GMT (7PM EST;8PM EDT).
• These records are NOT official and differ from official records that use a longer database and local (not GMT) time.
• Only cities having an NCDC GSOD recorded history of at least 35 years are shown here.
• With the additional year of data available (2024), 83 new stations (for a total of 3823) now meet the 35 year minimum record.
• In cases when there are multiple years of records for a city, the latest (most recent) year is shown above.
• Note that given the relatively short record used here (as small as 35 years), records will almost assuredly be set somewhere every day for the next several decades to centuries.
• Appreciation to R. Maue, E. Blake, and R. Remondelli, among several others, for feedback.
