Welcome to The Ontario Weather Page Archives.

Well one of my big pet projects is finally completed. I have amassed a huge database of over 300,000 weather entries for the main weather stations in Ontario from 1994 to December 2002. This is the complete works of all data that is available for the 57 stations in Ontario. Details regarding this data are below. This information is taken from data files almost 4 gigs large. Hope you like it.

This information is posted on this site in accordance with WMO Resolution 40.The following data and products may have conditions placed on their international commercial use. They can be used within the U.S. or for non-commercial international activities without restriction. Re-distribution of these data by others must provide this same notification.

Comments about the data:
  • Missing data in Temperature, Dewpoint, Sea Level Pressure, Max Temperature and Min Temperature are marked as 9999.9
  • Missing data in Visibility, Windspeed, Max Windspeed, Gust, Snow Depth and Precipitation are marked as 9999.9
  • Many stations may not report days with no precipitation or snow depth so these are marked as 999.9 instead of 0
  • This is the complete list. If the data is not their, it is not available at this time.
  • Not all stations report all data or dates.

Search the database using the criteria in the drop-down menus below. I have set it up so that you may retrieve the information in monthly blocks only. Please choose your station and then the month and year.

Station Data Is For 2002! Station Data from 1994 to 2001 has been taken offline due to hosting space being exceeded. I am looking for someone to host this for free but not having any success.
